Introducing the PLA4215

1.1 Overview

This chapter introduces the main applications and features of the PLA4215 HomePlug AV compliant powerline adapter.

This chapter introduces the main applications and features of the PLA4215 HomePlug AV compliant powerline adapter.

In this User's Guide the electrical wiring network is referred to as the "powerline network". The HomePlug AV standard specifies how network devices communicate using standard electrical wiring.

1.2 Expand Your Network with the PLA4215

The PLA4215 plugs into an ordinary power outlet to easily extend a cable or DSL broadband connection or existing Ethernet (LAN) network to any other electrical outlet in any room of a house, all without the need for any new cabling. Devices can securely communicate with each other at high data transfer rates. The PLA4215 uses 128-bit Advanced Encryption Standard (AES) to ensure safe transfer of information.

Figure 1 Expand Your Network with the PLA4215

Connect your PLA4215 to an Internet gateway such as a modem and plug it into an ordinary power outlet in your home. Plug a second PLA4215 into another power outlet and connect a computer to the PLA4215 for Internet access. Your network can be further expanded by plugging additional PLA4215s into other outlets in your home and connecting other computers or network devices (for example, a printer) to them. With a power socket, the PLA4215 can provide power to another device or connect to a power strip that allows more electrical devices, such as a printer or computer to be plugged.

Refer to your Quick Start Guide for hardware connection information.

1.3 Ways to Manage the PLA4215

Use the ENCRYPT button to add powerline devices to your powerline network if they have this button. See Chapter 3 on page 21 for instructions on using the ENCRYPT feature.

Use the PLA42xx Series Configuration Utility (or utility, for short) to manage the PLA4215. See Section 2.2 on page 14 for instructions on installing the utility.

Note: This User's Guide describes the latest version utility. This utility is only compatible with a PLA4215 which has the latest firmware installed. If you don't already have them, download the latest firmware and utility from the ZyXEL website.

1.4 Security

Since your powerline network may extend outside your premises, it is important to set up security on your PLA4215.

1.4.1 Passwords

You use two types of passwords in the HomePlug AV powerline network. The following table describes the differences between the passwords.

Table 1 Password Summary

PASSWORD DESCRIPTION
Network Name	All powerline adapters that follow the HomePlug AV standard are shipped with the same powerline network name “HomePlugAV”. Change the network name via the PLA42xx Series Configuration Utility to create a private network. See Section 4.3 on page 27.
DAK (Data Access Key) Password	In order to manage the powerline adapters on your powerline network you must enter the adapters’ DAK password in the PLA42xx Series Configuration Utility. This password is printed on the powerline adapter itself.You don’t need to add the password for the powerline adapter directly connected to the computer running the configuration utility (local powerline adapter), you only have to add the remote powerline adapters' passwords (those on your circuit, but not directly connected to your computer).

1.4.2 Setting Up Security

The ENCRYPT feature automatically sets up security on your powerline network. Use this feature if your powerline devices have the ENCRYPT button.

If your devices do not have the ENCRYPT button, use the PLA42xx Series Configuration Utility to set up security on the PLA4215. Although the PLA4215 is a "plug-and-play" network expanding solution there are several reasons for enabling security on the powerline network in your home.

1 It's easy and only requires you to change a network name.

2 It's a good idea to ensure privacy of your communication. When you use the PLA4215 and other powerline adapters, the electrical wiring in your home becomes an extension of your Ethernet network. Your network traffic flows freely within the electrical circuit of your home and is bounded in most cases by a power meter.

Without security (encryption) your information is accessible to anyone using a powerline adapter on the same electrical circuit. In some cases, a circuit can be shared by more than one household.

To prevent compromising your network security, you can create a private network. A private network uses a secret password (Network Name) to make sure that only permitted powerline adapters can communicate in your network. See Section 4.3 on page 27 for information on setting up a private network.

3 You may need to change the Network Name to create multiple powerline networks. See the next section for more information on how to set up a multiple network.

1.5 Multiple Networks

Multiple powerline networks can coexist on a single powerline circuit. You might want to implement multiple powerline networks in a small office environment where you have two separate Ethernet networks.

1 Connect one powerline adapter to a router or switch on the first Ethernet network and assign a Network Name (for example "Password1") to this powerline adapter. Add additional powerline adapters to your network by plugging them into your powerline outlets and assigning them "Password1". This completes the configuration of your first powerline network.

2 Connect another powerline adapter to a router or switch on the second Ethernet network and assign a different Network Name (for example "Password2") to this powerline adapter. Again, add additional powerline adapters and assign them "Password2".

You now have two private networks on your powerline circuit. Information is not shared between the two networks as only powerline adapters with the same Network Name can communicate with each other.

This chapter guides you through the installation of the configuration utility for your PLA4215.

2.1 Overview of the Installation Process

The installation of the configuration utility does the following:

1 Checks for and installs Microsoft's .NET Framework version 2.0 software on your computer. This software is necessary for the installation of the PLA42xx Series Configuration Utility. If you already have .NET Framework version 2.0 installed on your computer this step will be skipped.

2.3 Low Power Mode

Your PLA4215 is a certified green product. It goes into Low Power mode when there is no Ethernet connection.

When you plug the PLA4215 into an electric socket, it waits for an Ethernet connection. When no connection is detected after sixty (60) seconds, the Power LED blinks indicating that it is going into Low Power mode.

The same process occurs when you disconnect the PLA4215 from a previously working Ethernet connection. Sixty (60) seconds after disconnecting the Ethernet cable, the PLA4215's Power LED blinks signalling that it is going into Low Power mode.

The Ethernet and HomePlug LEDs are turned off in Low Power mode.

While in Low Power mode, you cannot use the ENCRYPT button. To enable the ENCRYPT button again, you have to connect the PLA4215's Ethernet cable to a computer/notebook or modem/router first. The PLA4215 wakes up from Low Power mode and you can start using the ENCRYPT button.

Low Power mode is enabled by default.

PART II

Technical Reference

The ENCRYPT Button

Use the ENCRYPT button to automatically set up a secure powerline connection between your powerline devices.

3.1 ENCRYPT Button Overview

The ENCRYPT button allows you to set up a secure powerline connection with other HomePlug AV compliant powerline devices which also support the ENCRYPT feature. No other powerline setting changes are required to connect.

You can use the ENCRYPT button to:

• set up a new powerline network
• separate an existing powerline network into multiple networks

3.2 Set Up a HomePlug AV Network with ENCRYPT

You can connect a number of devices on a powerline network, but you can use the ENCRYPT button on only two devices at a time.

Place a powerline device close to another powerline device so you have time to set up each one. After you set up the first powerline device, you have 120 seconds to set up the second powerline device.

You can disconnect them from your computer or modem (or other networking equipment) if you need to move them close to each other, but the powerline devices need to be plugged into power outlets.

Note: Because your PLA4215 goes into Low Power mode, it must be connected to a networking equipment for the ENCRYPT button to work. Refer to Section 2.3 on page 16 for more details.

Follow the steps below to set up your HomePlug AV Network:

1 Press the ENCRYPT button at the rear of your powerline device for more than 10 seconds until the power (⏻) light flashes. This resets the network name to a random value and removes your device from any network it may belong to.

2 Press the ENCRYPT button at the side of your powerline device for 1\~2 seconds. The power (💡) light will blink as the powerline device tries to set up a connection.

    B --> D["Time: within 2 minutes"]
    D --> E["Hourglass with directional arrow and red/green indicators"]

Note: The ENCRYPT button's location varies for each Powerline model.

3 Repeat step 2 in this section for the other powerline device you wish to connect. This must be done within 120 seconds of pressing the ENCRYPT button on the PLA4215.

Note: Check the lights on the two powerline devices. The power ( ) and HomePlug ( ) lights should be blinking while the devices are connecting. Several times all lights blink simultaneously and the HomePlug ( ) light also shows red. Wait for about one minute while your powerline devices connect.

If the power ( ⏻ ) light does not blink when you press ENCRYPT, you have probably pressed the ENCRYPT button for too long. Try again, pressing the ENCRYPT button for 1\~2 seconds.

If the HomePlug ( lights on both powerline devices do not light up, the powerline devices are not connected. Repeat steps 2 and 3 in this section. If that doesn't work, see the Troubleshooting in Section 6.5 on page 51 for suggestions.

4 To add more powerline devices to your network, press the ENCRYPT button on device C (shown below) for more than 10 seconds until the power (light flashes.

5 Then repeat steps 2 and 3 in this section using any powerline device (A or B) you have connected using ENCRYPT and the powerline device you want to connect (C). You must use the ENCRYPT button on both devices.

6 If you disconnected your computer or modem (or any other networking product connected to your powerline device) in step of this section, you can now reconnect them.

This sets up your powerline network between your powerline devices.

3.3 Setting Up Multiple Networks

You can use the ENCRYPT button to set up multiple powerline networks using your existing powerline network.

For example, you have already set up a powerline network in your home (A) which accesses a printer (B). Now you want a separate powerline network connection from your laptop to your printer (C).

1 Click the ENCRYPT button on (A) for more than 10 seconds until the power (☐) light flashes. This disconnects (A) from (B).
2 Click the ENCRYPT button on (A) and (C) for 1\~2 seconds and within two minutes of each other.
3 Wait for about one minute while (A) and (C) connect.
4 Check the LEDs on both (A) and (C). When the power (⏻) and HomePlug (⏻) lights stop blinking and the power ( lightning shines steadily, the devices are connected.

    style B fill:#ccf,stroke:#333
    style C fill:#cfc,stroke:#333

Congratulations. You now have two separate powerline networks as shown above.

If the HomePlug ( lights on both powerline devices do not light up, the powerline devices are not connected. Repeat the connection process, making certain you press the ENCRYPT buttons for the correct time and within two minutes of each other. If that does not work see Section 6.5 on page 51 for suggestions.

3.4 ENCRYPT Button Behavior

The following table summarizes the actions that occur when the ENCRYPT button is pressed for specific lengths of time.

Table 2 Time ENCRYPT Button is Pressed and Action

TIME ACTION POWER LIGHT BEHAVIOR			HOMEPLUG LIGHT BEHAVIOR
less than 3 seconds	The device joins a network. It shares the same network name as other devices on the network.	The power ( Light blinks until the device is connected. This may take a minute.	The HomePlug ( Light turns on if your device is connected to another powerline device or a powerline network.
more than 10 seconds	The device leaves any network it is associated with and its network name assumes a random value.	The power ( Light blinks several times and then shines steadily.	The HomePlug ( Light blinks red one time and then turns off when it disconnects from the powerline network.

See Troubleshooting in Chapter 6 on page 51 for suggestions on problems with the ENCRYPT button and the lights.

The Configuration Utility

4.1 Overview

This chapter shows you how to use the Configuration Utility (or Utility) to secure, manage and set up Quality of Service (QoS) on your powerline network.

The PLA4215 is designed as a plug-and-play network expanding solution. This means that once you complete your hardware connections, the PLA4215s in your network (without additional configuration) are able to communicate with each other by sending and receiving information over your home's electrical wiring (A).

Figure 11 Example Network Setup

    style B fill:#ccf,stroke:#333
    style C fill:#cfc,stroke:#333
    style D fill:#fcc,stroke:#333

All HomePlug AV compliant powerline adapters within range can join your network. The range varies depending on the quality of your home's wiring.

Note: See Section 4.1.1 on page 26 for more information on enhancing your powerline network security.

4.1.1 Powerline Network Security

When the PLA4215s communicate with each other, they use encryption to protect the information that is sent in the powerline network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. The HomePlug AV standard uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline adapters.

For the powerline adapters to communicate with each other they all need to use the same network name. This network name allows the powerline adapters to understand the encrypted information sent in the powerline network.

By default the PLA4215s are all configured with the network name HomePlugAV, this allows you to simply plug the devices in and not worry about setting up security. If you want to enhance the security on your powerline network, you can change the network name on the powerline adapters you want to allow to communicate in your powerline network.

4.1.2 Device Access Key (DAK)

In order to manage the powerline adapters on your powerline network you must enter the adapters' password in the PLA42xx Series Configuration Utility. This password is called the DAK (Device Access Key) password. This password is printed on the powerline adapter itself.

You don't need to enter the DAK password for the powerline adapter directly connected to the computer running the utility (local powerline adapter), you only have to add the remote powerline adapters' passwords (those in your powerline network, but not directly connected to your computer).

4.2 Starting the Configuration Utility

To launch the PLA42xx Series Configuration Utility simply double click on the configuration icon on your desktop.

Figure 12 PLA42xx Series Configuration Utility Icon

The following table describes the labels in this screen.

Table 3 Configuration Screen

LABEL DESCRIPTION
Network Topology	Use this to select which powerline network information is displayed. Different powerline networks are identified by the Ethernet interface (network card) connected directly to the PLA4215. Typically there is only one connection, however, if your computer has two network cards and both are connected to a powerline device then you have two powerline networks.
The fields described below are used to identify the powerline adapters recognized on the powerline network. The configuration utility automatically updates this information every 10 seconds. Click Scan to refresh the information in these fields (immediately).Note: Only devices which share the same network name are displayed in this table.
Site This field displaysLocal, if it is identifying the powerline adapter directly connected to the computer running the configuration utility.Remote, if it is a powerline adapter in your powerline network but not directly connected to the computer running the configuration utility.
MAC Address	This is a read-only field which shows the MAC address of the powerline adapter you are configuring. You can find the MAC address of your PLA4215 displayed on a sticker on the bottom of your device.
DAK Password	DAK (Device Access Key) password is used to verify that you are authorized to perform changes on a remote device. You can find the DAK password printed on a sticker on the bottom of your PLA4215.Select the remote powerline adapter you want to manage by clicking the MAC address which corresponds to it in the MAC Address column. Enter the DAK Password value and click Save.Note: You must enter the DAK Password value exactly as it is printed on the label (all caps and with dashes “-”).
Network Name (NMK)	The default network name (sometimes called a network password or network membership key (NMK)) of the PLA4215 is “HomePlugAV”. HomePlug compatible devices use the same network name to recognize and communicate with each other over the powerline network. If you change the network name of one device on the network, it will no longer be recognized as part of that network.If you change the network name, make sure you change the network name for all of the powerline adapters that you want to be part of your powerline network.The network name can be from 8 to 64 characters in length, using “A”~“Z”, “a”~“z”, “0”~“9”; spaces are not allowed.
Set NMK to this device	Select this to apply the NMK (entered in the field above) as the network name for the powerline adapter directly connected to the computer running the configuration utility.
Set NMK to all devices	Select this to apply the NMK (entered in the field above) as the network name for all powerline adapter detected by the utility.
Save	Click this to apply your changes. The new Network Name is applied to the selected powerline adapter.Note: You must enter the correct DAK password for the selected powerline adapter before you can make changes to it.

4.4 Firmware Screen

Use the Firmware screen to update the firmware on the PLA4215 directly connected to the computer running the configuration utility.

Firmware is the software which is embedded in the PLA4215. This software contains processing instructions for how the PLA4215 sends and receives information in a secure way.

Parameter Information Block (PIB) is similar to firmware. It contains the most basic operating instructions for the PLA4215 such as how to power up and how to load the firmware.

You can check the ZyXEL website for firmware upgrades for your PLA4215.

Note: If you have upgraded the firmware, make sure you also upgrade the PLA42xx Series Configuration Utility. Older version utilities are not compatible with PLA4215s using the latest firmware.

The following table describes the labels in this screen.

Table 4 Network Info Screen

LABEL DESCRIPTION
Adapter This field	Identifies which powerline network information is displayed. Different powerline networks are identified by the Ethernet interface (network card) connected directly to the PLA4215. Typically there is only one connection, however, if your computer has two network cards and both are connected to a PLA4215, then you have two powerline networks.
Central Coordinator MAC	The Central Coordinator of the powerline network is the powerline adapter which keeps track of which devices are part of the network as well as synchronizes communication within the powerline network. If the Central Coordinator is removed from the powerline network then another powerline adapter takes its place. This field displays the MAC address of the PLA4215 which is the Central Coordinator of the powerline network. The powerline adapters in your powerline network automatically select the Central Coordinator.
The information provided in the following table reflects transmission rate information about the powerline adapters which communicate in your powerline network.The powerline adapters listed in this table are all the powerline adapters in your powerline network except the powerline adapter selected in theConfigurationpage of the configuration utility. In other words, if theLocalpowerline adapter is selected in theConfigurationscreen, then this table will display the rates of transmission from the powerline adapter connected to the computer running the configuration utility to all theRemotepowerline adapters.
Site This field displays:Local, if it is the PLA4215 directly connected to the computer running the configuration utility.Remote, if it is a PLA4215 in your powerline network but not directly connected to the computer running the configuration utility.
MAC Address	This field displays the MAC address of your powerline adapter. The MAC address of your powerline adapter can be found by looking at the label on your device. It consists of six pairs of hexadecimal characters (hexadecimal characters are “0-9” and “a-f”). In the case of the PLA4215, this label is on the bottom of the device.
Transmit Rate (Mbps)	This field displays how fast information is sent from the powerline adapter selected in theConfigurationscreen to this powerline adapter. The rate is given in the following format: “application data transmission rate / raw data transmission rate”. Application data reflects more accurately how fast devices are transmitting application relevant traffic (for example Internet Protocol (IP) traffic). Raw data refers to the whole payload of the packets transmitted across the powerline network.
Receive Rate (Mbps)	This field displays how fast information is received from the powerline adapter selected in theConfigurationscreen to this powerline adapter. The rate is given in the following format: “application data transmission rate / raw data transmission rate”. Application data reflects more accurately how fast devices are transmitting application relevant traffic (for example Internet Protocol (IP) traffic). Raw data refers to the whole payload of the packets transmitted across the powerline network.

4.6 Advanced Screen

Note: This feature is only available with the latest version utility. Go to the ZyXEL website to download the latest utility and firmware for your ZyXEL HomePlug AV adapter.

You can configure the powerline adapters on your network to give priority to network traffic depending on its importance. When you set the priority of a powerline adapter, you set how quickly

messages FROM your powerline adapter are sent in your powerline network. Transmissions TO your powerline adapter do not receive any priority.

For example, if you have a file server on your home network to deliver music and movie files to computers in your home, you should set the priority of the powerline adapter connected to this server to Medium. If video traffic is delivered too slowly, quality problems may occur.

On the other hand, a powerline adapter attached to a printer should have a low priority setting since the slow delivery of messages will not affect the print job.

Similarly, if you want to prioritize any downloads from the Internet, set the priority on the powerline adapter attached to your Internet gateway to High.

Allocate priority settings based on application type as follows.

Table 5 Priority Settings

PRIORITY LEVEL APPLICATION
High Voice Application
Medium Video and Audio	Applications
Normal Data Applications
Low Data Applications

The figure below shows an example powerline home network connected to the Internet.

• Device A is a printer and does not handle traffic with high importance, so the powerline adapter connected to it can be set to low priority.
• Device B is a file server, delivering audio or movie files to other users on the network. The powerline adapter attached to it should have a medium setting.
• Device C, a home computer which connects to the Internet, can receive a normal priority setting as it usually sends simple requests for data. For example, when you surf the Internet, your computer sends requests to open web pages.
• Device D is a modem attached to the Internet. It should receive a high priority setting if you want faster downloading through your network.

- Although device E receives audio or movie files, it does not send a lot of traffic, so the powerline adaptor attached to it can be set to a low priority.

- If you want to access any of your new powerline networks using the PLA42xx Series Configuration Utility, change the Network Name on your local adapter to the network name for the network you want to access. The adapters on that network will then display in the adapter table, allowing you to select and configure each one.

5.6 Troubleshooting

The HomePlug (▲) LED (light) should light up on your adapter when it successfully connects to other adapters on your network. If it does not, try the following measures.

- Make sure the adapter is plugged in to a power socket and the power socket is turned on.

• Check you have entered the correct network name for your network.
• Check your powerline adapter is connected to the same electrical circuit as other powerline adapters on your network.

LEDs and Troubleshooting

This chapter describes the behavior of the LEDs (lights) and offers some suggestions to solve problems you might encounter.

6.1 LEDs

The following sections describes the lights on the PLA4215.

The following figure is the front panel of the PLA4215. Use the lights to determine if the PLA4215 is behaving normally or if there are some problems on your powerline network.

Figure 34 PLA4215 Lights

		Green/ Amber/ Red	Blinking The PLA4215 is communicating with another powerline adapter. Data is being transmitted and/or received. Blinking at the same time as the POWER light indicates an unsuccessful connection if you have used the ENCRYPT button.
			Off The HomePlug port does not detect another powerline adapter.
ETHERNET		Green On	The ETHERNET port is on and ready and the PLA4215 detects a device connected to it.
			Blinking The PLA4215 is communicating with a networking device connected to it.
			Off The PLA4215 does not detect any devices connected to its ETHERNET port.

6.2 Power and Light Problems

The PLA4215 does not turn on. None of the lights turn on.

1 Make sure you are using the power cord included with the PLA4215.
2 Make sure the power cord is connected to the PLA4215 and plugged in to an appropriate power source. Make sure the power source is turned on.

3 Disconnect and re-connect the power cord to the PLA4215.

4 Remove the powerline adapter from the outlet. Then connect an electrical device that you know works into the same power outlet. This checks the status of the power outlet.

5 If the problem continues, contact the vendor.

The ETHERNET light does not turn on.

1 Check the hardware connections. See the Quick Start Guide.

2 Inspect your cables for damage. Contact the vendor to replace any damaged cables.

3 Check the Ethernet adapter on your computer and make sure it's enabled and working properly.

4 If the PLA4215 is connected to an Ethernet switch or router, make sure the device is working correctly, and that the LAN network is working and configured correctly as well.

The HomePlug light does not turn on.

1 Check all PLA4215s on your network have the latest firmware installed. PLA4215s with the latest firmware cannot communicate with PLA4215s using earlier versions of the firmware. Go to Section 4.4 on page 29 for instructions on installing the latest firmware.

2 Use the PLA42xx Series Configuration Utility to detect all other HomePlug devices on your powerline network. Make sure that the network name (sometimes called the network password) is the same on all of your powerline adapters. See Section 4.3 on page 27 for instructions on checking the network name.

3 Check the DAK password and MAC address for all powerline adapters are typed correctly in the utility. See Section 4.3 on page 27 for instructions on checking the DAK and MAC address.

4 Make sure that all your powerline adapters are HomePlug AV compliant. Check the package it came in or ask your vendor. This PLA4215 can not detect earlier versions of HomePlug powerline adapters such as HomePlug 1.0 or 1.0.1. (Although they can coexist on the same electrical wiring without interfering with each other.)

5 Make sure that the powerline adapters on your network are all on the same electrical wiring. Connect another powerline adapter into an outlet close to your PLA4215's power outlet. They are probably now on the same electrical wiring. Check the HomePlug light. If it now lights up your powerline adapter was probably previously on separate electrical wiring. Ask an electrician for more information on the electrical wiring in your building.

6 If your powerline network is using coaxial cable, check all powerline adapters are on the same coaxial cable.

7 If your powerline network is using electrical wiring (not coaxial cable), check you do not have a power meter between powerline adapters. Powerline signals cannot pass this.

The POWER and HomePlug light blink at the same time.

- You have pressed the ENCRYPT button for more than three seconds. Try setting up a connection again, this time pressing the ENCRYPT buttons on both devices for less than three seconds.

6.3 Configuration Utility Problems

The PLA42xx Series Configuration Utility displays an error during installation.

- Make sure your computer is using Windows XP or Windows Vista (32-bit) operating system. At the time of writing, this is the only compatible operating system for the configuration utility.

The PLA42xx Series Configuration Utility does not display all or any of my devices.

• Inspect the LEDs on your PLA4215 and make sure that the ETHERNET and HomePlug LEDs are on or blinking. See Section 6.1 on page 47 for troubleshooting LED related problems.
• Check all ZyxEL HomePlug AV devices on your network have the latest firmware installed. The latest utility cannot communicate with PLA4215s using earlier versions of the firmware. Go to Section 4.4 on page 29 for instructions on installing the latest firmware.
• Check you are using the latest version utility. Earlier version utilities cannot communicate with PLA4215s using the latest firmware. If you do not have the latest utility, download it from the ZyXEL website.
• If the device is not a ZyXEL device, then the DAK and Network Name will be greyed out.
• If you are running another tool such as the Firmware Detection Tool, the Utility will not detect your local device.

6.4 Powerline Problems

The signal on my powerline network is weak.

1 Your powerline adapters may be connected to electrical surge protectors. Connect them to standard power outlets.
2 Your powerline adapters may be located close to large appliances such as refrigerators or air-conditioners that cause interference with the powerline signal. Move the adapters further away from such appliances to reduce interference.

3 Your powerline adapters may be placed close to electrical devices such as electrical insect-killers which produce radio waves. These may interfere with the powerline signals. Move the adapters further away from such electrical devices.
4 Your wiring may be old and/or low quality or with a long wiring path.

6.5 ENCRYPT Button Problems

This section applies only to PLA4215s with the ENCRYPT button.

The HomePlug light is already on, but I haven't pressed the ENCRYPT button yet.

Your device has already connected to another powerline device. Press the ENCRYPT button for more than 10 seconds to release the connection.

The POWER light does not blink when I press the ENCRYPT button.

• Check the device is on.
• Press the ENCRYPT button again, making certain you have pressed the button for more than one second and less than three seconds.
• The POWER light on some powerline devices do not blink as part of the ENCRYPT process. Check your powerline device is a PLA4215.
• For PLA4215, you cannot use the ENCRYPT button when it is in Low Power mode. Connect the PLA4215 to a computer/router then try again.

The POWER light blinks two times quickly then pauses, before repeating.

The ENCRYPT process has failed. Press the ENCRYPT button on both devices for more than 10 seconds, then try to reconnect.

The POWER lights on both devices blink when I press the ENCRYPT buttons, but the HomePlug light does not turn on.

• Ensure you have pressed the ENCRYPT button on both devices.
• Wait for about a minute while the devices set up a connection.
• If that does not work, try again with both devices connected to a power strip next to each other. If they now connect, then the devices were not on the same electrical circuit before.

The POWER lights on both devices blink, then many lights blink and the HomePlug light blinks red.

Do not worry, the connection process is proceeding normally.

The POWER lights on both devices finished blinking, but only one device's HomePlug light is on.

One device may have connected to a third powerline device. To check device A is connected to device B and not another device, disconnect device B from its power source. Device A's HomePlug (▲) light will turn off if the connection is with Device B. Press the ENCRYPT button on both devices for more than 10 seconds, then try to reconnect, pressing the ENCRYPT button for less than 3 seconds on both devices.

I pressed the ENCRYPT button for more than 10 seconds, but the HomePlug light is still on.

The HomePlug light is on, indicating it is still connected to another powerline device. Try again, pressing the ENCRYPT button for more than 10 seconds.
