Frequently Asked Questions - NPort 6650-32-48V Moxa

How do I assign an IP address to the NPort 6650-32-48V?

Use the NPort Search Utility (Windows) to discover the device on your network and assign a static IP, or configure via DHCP. Alternatively, access the serial console with factory default settings (192.168.127.254).

What serial port modes are supported?

The device supports Real COM, TCP Server, TCP Client, UDP, and RFC2217 modes. Each of the 32 ports can be configured independently.

Can I use the NPort with both RS-232 and RS-422/485 devices?

Yes, each serial port can be individually configured for RS-232, RS-422, or 2-wire/4-wire RS-485 via DIP switches or software settings.

How do I recover the factory default settings?

Press and hold the Reset button on the front panel for 5 seconds while powering on, or use the Reset to Default option in the web interface.

What are the power requirements?

The 48V model requires a 48 VDC power supply. Connect to the terminal block; ensure proper polarity. Power consumption is typically 35 W maximum.

How many Ethernet ports are available?

It features two Gigabit Ethernet ports (RJ45) for redundant network connections or separate LAN/WAN links.

Does the device support secure communications?

Yes, it supports SSL/TLS for encrypted web access, SSH for secure console, and HTTPS for secure configuration. Also supports IP address filtering.

What is the operating temperature range?

The NPort 6650-32-48V operates reliably from 0°C to 60°C (32°F to 140°F), suitable for industrial environments.

How do I update the firmware?

Download the latest firmware from the Moxa website, then upload via the web interface (Maintenance > Firmware Upgrade) or use the NPort Search Utility.

Can I mount the device in a standard 19-inch rack?

Yes, it comes with rackmount brackets and fits a 1U (44 mm) rack space. The width is 440 mm (19 inches).

Overview

The NPort 6600 series of serial device servers includes 8-port, 16-port, and 32-port models for connecting larger numbers of serial devices to Ethernet. Some applications now also require better security when transmitting data through a network. The NPort 6600 series of device servers use DES, 3DES, and AES data encryption to provide secure network communication.

Press the Reset button continuously for 5 second to load factory defaults: Use a pointed object to press the reset button. Release the button after the Ready LED stops blinking.

RS-485 adjustable pull up/down resistor (150/1 KΩ)

The NPort 6650 has 3 DIP Switches associated with each serial port for configuring the pull up/down resistors for RS-485 applications. The switches are located in a recess on the bottom of the NPort 6650. To access the switches, first remove the panel covering the recess.

DIP-Switches

SW	1	2	3
	Pull Up	Pull Down	Terminator
ON	1 KΩ	1 KΩ	120 Ω
OFF	150 KΩ	150 KΩ	-

NOTE For RS-232 applications, all DIP Switches for the port should be set to the OFF position.

Rack Mounting

Use four screws to attach the NPort 6610/6650 to a standard rack.

Hardware Installation Procedure

STEP 1: Connect the NPort 6600 device server to a suitable power source. AC models: Connect the 100 to 240 VAC power cord to the NPort 6600's power input.

DC models: Connect the terminal block to a battery.

STEP 2: Connect the NPort 6600 series to a network. Use a standard straight-through Ethernet cable to connect to a hub or switch. Use a cross-over Ethernet cable when connecting to your computer's Ethernet port (e.g., when setting up or testing the NPort 6600 server).

STEP 3: Connect the NPort 6600's serial ports to your serial devices.

Software Installation Information

For the NPort's configuration, the default IP address of the NPort is 192.168.127.254. You may log in with the account name admin and password moxa to change any settings to meet your network topology (e.g., IP address) or serial device (e.g., serial parameters).

For software installation, download the relative utilities from Moxa's website:

https://www.moxa.com/support/support_home.aspx?isSearchShow=1

• Download the NPort Windows Driver Manager and install it as the driver to run with Real COM mode of the NPort Series.
• Execute NPort Windows Driver Manager; then map the virtual COM ports on your Windows platform.
• You may refer to Pin Assignment Async RS-232 port section to loop back pin 4 and pin 5 for the RS-232 interface to carry out a self test on the device.
• Use HyperTerminal or a similar program (you may download Moxa's program, called PComm Lite) to test whether the device is good or not.
