Introduction

WELCOME

Thank you for choosing the ADDERLink® XD641 (single head) or XD642 (dual head) extender modules. Using either fiber optic or CATx links, these compact modules allow you to extend KVM connections over long distances from a host computer (see Transmission distances when using fiber on the right).

The high-grade screening employed within the metal cased enclosures, particularly when combined with the immunity from interference of the fiber optic links.

AdderLink XD64x extender modules provide support for:

• High quality single- or dual- digital video (up to 4K 4096 x 2160 @60Hz),
• USB keyboard and mouse plus two other USB devices (up to USB 2.0),
• An RS232 serial device at speeds up to 115200 baud,
- Mono microphone,
- Stereo speakers,
• Line-level audio in/out connections.

The ADDERLink extender modules are totally transparent in operation, leaving you free to use your computer as though you're still sitting next to it.

Transmission distances when using fiber

The choice of fiber used with the ADDERLink XD64x modules has a considerable effect on the distance over which operation can take place. Using multi-mode fiber you can achieve distances up to 400m (1,312 feet); whereas, by using single-mode fiber (and accompanying SFP+ modules), the achievable maximum distance is increased to 4km (2.5 miles):

Distance	Fiber type	Fiber color code	SFP+ module
70m	OM1 (TIA-492AAAA)	Orange	SFP-MM-LC-10G
150m	OM2 (TIA-492AAAB)	Orange	SFP-MM-LC-10G
380m	OM3 (TIA-492AAAC)	Aqua	SFP-MM-LC-10G
400m	OM4 (TIA-492AAAC)	Aqua	SFP-MM-LC-10G
4km	OS1 (TIA-492C000)	Yellow	SFP-SM-LC-10G
	OS2 (TIA-492E000)	Yellow	SFP-SM-LC-10G

Note: Adder supplied SFP+ modules are recommended. If using alternatives, ensure that they are 10G SFP+ parts with LC connectors.

CATx Link Cable Recommendations

Due to the high data bandwidth required between the transmitter and receiver, ADDERLink XD600 series modules are highly dependent upon good quality CATx cable links. Video performance is particularly reliant on high speed communication channels.

The main factors that affect link quality are:

• The length and type of CATx cable used,
- The number, length and type of intermediate patch connections,
• The quality of the cable terminations.

CAT6 is recommended for CATx extensions, with a gauge (thickness) of at least 23AWG. Up to 5Gb/s of data may be transmitted, so the cable must be rated for at least 5GBase-T or 250MHz.

Patch links affect performance. For each additional break/patch within a run, the overall maximum extension is likely to be reduced. The amount will be dependent upon the nature of the patch panel. For best results, patch cables should be of type CAT6 and be less than 2 meters in length.

Use of CAT7 cables is not recommended. There is no associated ANSI/TIA specification for CAT7 resulting in a wide range of cable quality available, particularly with regard to shield grounding.

Do not place the products in contact with equipment whose surface temperature exceeds 40 degrees Centigrade.

Linking

ADDERLink XD641 and XD642 units can be linked using either:

• CATx (see below), or

- Fiber (see next page)

When fiber is used there are no limits to the resolutions that can be transferred, up to the maximum 4K (4096 x 2160); when a CATx link is used, the maximum resolution for dual head installations on XD642 models will be WQXGA (2560 x 1600).

Fiber CATx

ADDERLink XD641 Single head at 4K maximum Single head at 4K maximum

ADDERLink XD642

Dual head at 4K maximum

Single head at 4K maximum

Dual head at WQXGA maximum

Distances up to 4km

Distances up to 100m

CATx link

The CATx ports on each module (labeled Link A) allow you to create direct links of up to 50m (when using CAT5e) or 100m (when using CAT6). In order to work in CATx mode, the SFP+ fiber modules must be removed from their sockets.

Note: The CATx ports are not network ports and should not be connected to network switches or computer ports.

To make the CATx link

Connect a CATx (CAT 5e or 6 as required) cable between the Link A ports on the transmitter (front panel) and the receiver (rear panel):

2 In operation, ensure that both indicators on the CATx connectors are green. See right.

CATx status indicators

The status indicators on the CATx port connector of each module provide further status information when a CATx link is in use:

Simple diagram of a network switch or socket with two green ports and three terminal lines (no text or labels)

* The CATx LINK LED will be either yellow or green, depending upon the connector manufacturer used. There is no difference in functionality.

Fiber optic link

Each pair of AdderLink XD64x modules require optional SFP+ fiber optic modules of your choice (single or multi-mode). The fiber optic cable used must match the SFP+ type and also be of a suitable type for the distance being covered. See Transmission distances for details.

To make the fiber optic link

IMPORTANT: Ensure the power supply is off/disconnected before inserting or removing an SFP+ module.

1 Remove an SFP+ module from its protective packing and insert it fully into the empty slot on the AdderLink XD641. The XD641 transmitter slot is located on the front panel; the XD641 receiver slot is situated on the rear panel:

2 Repeat for the other SFP+ module on the other XD641.
3 For each SFP+ module, remove the black rubber insert that protects the sensors.
4 If fitted, remove the dual inserts that protect the fiber optic connectors.
5 Insert the fiber optic connectors into the SFP+ module so that they click into place:

6 Repeat steps 4 and 5 at the other end.

Note: In order to maintain a high level of confidence in the fiber optic link, it is recommended that Adder supplied SFP+s are used: (SFP-MM-LC-10G or SFP-SM-LC-10G).

To remove an SFP+ module

If fitted, remove the dual fiber optic connectors from the SFP+ module (press in the release tab of the fiber optic connectors to disengage them).
2 Unclip the small extraction lever and open it out (this action releases a locking tab and also provides a grip point).

3 Gently pull on the extraction lever to withdraw the SFP+ module from the slot.
4 If the SFP+ module and/or fiber optic connector will remain unused for any period of time, be sure to fit the protective inserts to keep the optical interfaces clean.

Receiver video display(s)

Two DisplayPort sockets are provided on the rear panel of each receiver module. On XD641 models, the signal from port 1 is duplicated on port 2. On XD642 models, ports 1 and 2 operate independently to supply the signals introduced to video ports 1 and 2 on the transmitter.

Note: On XD642 models, dual video displays at 4K resolution are not possible using a CATx link

- fiber must be used. However, dual WQXGA resolutions are possible using CATx.

3 Connect the power cord to a nearby mains supply socket.

To disconnect the power adapter

I Isolate the power adapter from the mains supply.
2 Grasp the outer body of the power adapter plug where it connects with the module.
3 Gently pull the body of the outer plug away from the module. As the body of the plug slides back, it will release from the socket and you can fully withdraw the whole plug.

Gently pull back the plug outer body to release the lock

IMPORTANT: Please read and adhere to the electrical safety information given within the supplied safety leaflet. In particular, do not use an unearthed power socket or extension cable.

Note: Both the modules and the power supplies generate heat when in operation and will become warm to the touch. Do not enclose them or place them in locations where air cannot circulate to cool the equipment. Do not operate the equipment in ambient temperatures exceeding 40 degrees Centigrade. Do not place the products in contact with equipment whose surface temperature exceeds 40 degrees Centigrade.

Configuration

ACCESSING THE DASHBOARD

AdderLink XD64x modules generally configure themselves automatically, collecting EDID information from the attached monitor(s) and passing the details to the host computer. Unless an issue is encountered, the modules will begin working together correctly as soon as they are connected. The front panel indicators provide the primary source of status information, however, there is also a Dashboard popup which provides certain other details on the primary console display.

To access the dashboard

Using your console keyboard attached to the receiver module, press (and release) the Ctrl key three times in quick succession (either of the keyboard's Ctrl keys can be used). In response, the three keyboard indicators will all flash, once per second.
2 Press the numeric key 1 located above the main section of the keyboard (not the numeric keypad).

The Dashboard will be displayed, similar to this:

The example above shows a configuration that is working correctly.

If the communication link was working correctly, but the video signal was lost, it might report as follows:

If the communication link was missing then the dashboard would report the issue similar to this:

To exit the dashboard

- Press (and release) the Ctrl key three times in quick succession and then press the numeric key I located above the main section of the keyboard (not the numeric keypad).

CHOOSING THE DUAL HEAD MODE (XD642 models only)

When the CATx link is used to connect the transmitter and receiver modules, the available bandwidth is reduced. On XD642 models, if dual high resolution video displays are used, you can determine how the available bandwidth is shared between them. Two modes are available:

• Balanced mode - Shares the available video bandwidth equally between the two video displays, regardless of the EDIDs being reported by them, e.g. 1920x1200 each on video displays that would ordinarily request a native mode of 2560x1600.
• Priority mode - The primary video port will take priority, allowing it to display resolutions up to 4K, as reported by its EDID. The remaining bandwidth will be assigned to the second video head.

To choose the dual head mode

Using your console keyboard attached to the receiver module, press (and release) the Ctrl key three times in quick succession (either of the keyboard's Ctrl keys can be used). In response, the three keyboard indicators will all flash, once per second.
2 Press the numeric key located above the main section of the keyboard (not the numeric keypad) which represents the required mode:

• 6 for Balanced mode,

- 7 for Priority mode.

The current mode will be displayed on the Dashboard next to the link speed, eg BAL 5G, PRI 5G.

Note: If you do not press any key within five seconds, or press any key other than the digits 1, 6 or 7 (or once you have successfully chosen an action), the keyboard will revert to normal operation. To use another hotkey function, repeat the whole procedure described above.

The color of the Dashboard's Link Quality indicator matches the front panel LNK indicator:

• Red 0-25% quality
- Amber 25-50% quality
• Yellow 50-75% quality
• Green 75-100% quality

RESETTING A MODULE

On the left side of the front panel of each module, you will find a small reset hole which is used to invoke special functions.

To reset a module

I Use a thin implement, such as a straightened paperclip to press and release the button concealed behind the small hole. The PWR indicator will show red.

After a few seconds, the indicator will change from red to green to show that the reset procedure is complete.

UPGRADING FIRMWARE

Firmware upgrades are periodically made available for products via the Adder website (www.adder.com). Use this procedure to upgrade the firmware in both ADDERLink XD64x extenders. Note: Upgrades require roughly 6 minutes to complete.

To upgrade the firmware

Download the appropriate firmware upgrade file from the Downloads section of the ADDERLink XD64x product page within the Adder website. Copy the upgrade file to an empty (but FAT32-formatted) USB memory stick.

2 Ensure that the transmitter and receiver are linked and powered on. Also check that there are no USB drives inserted in the receiver module's ports.

3 On the receiver, press and hold a thin implement, such as a straightened paperclip, in the reset hole until the receiver's STS indicator flashes red/blue. The receiver is now in upgrade mode.

4 Wait for the LNK indicator to turn green, signifying that the link has been established. Video from the transmitter should be displayed and the STS indicator will continue to flash red/blue.

5 Insert the memory stick containing the upgrade file into the front panel left USB port.

The upgrade should begin and both units will flash their STS indicators red/

green to show the upgrade process is in progress. Following a successful upgrade, both units will automatically reboot and run the new firmware. The STS indicator will show green for a copper connection and blue for fiber.

Display the Dashboard (see page 18) to view the upgrade progress. The Status field will display a message if an error occurs. In an error situation, it may be necessary to reboot the modules to use the existing firmware version.

Operation

The AdderLink XD64x modules are designed to be transparent in operation; all peripherals should respond exactly as they would when situated next to your host computer.

INDICATORS

The transmitter and receiver modules contain various indicators to provide you with status information. Both modules have four red indicators on their front panels.

Status indicators

The multicolor status indicators on the front panels of each module mostly behave in the same manner at the same time:

PWR

This indicator shows red while the module is performing its initial boot procedure and changes to green when ready. The indicator will flash red if a problem is encountered - remove power and re-apply to see if the problem persists.

STS

This indicator shows which link-type is being used:

• Alternating red/blue - Upgrade mode
• Alternating red/green - Upgrade in progress
• Blue - Fiber 10G link in use
• Green - CATx 5G link in use
• Amber - Warning, see
Dashboard for details (page 18)
- Red - Error, see Dashboard for details (page 18)

VID

This indicator shows the status of the video connections:

• Off - no video displays
connected
• Red - displays connected, no video on any display
• Amber - displays connected, video only on one (XD642 only)
• Green - displays connected, all have video

LNK

This indicator shows the status of the link between the transmitter and receiver modules:

• Off - no link
  • Red - 0-25% quality
  • Amber - 25-50% quality
• Yellow - 50-75% quality
  • Green - 75-100% quality

CATx status indicators

The status indicators on the CATx port connector of each module provide further status information when a CATx link is in use:

LINK

This indicator will be green or yellow*

CATx link between the transmitter and receiver modules.

SPEED

This indicator signals whether the speed of the CATx link is sufficient:

• Amber - link speed is below the necessary 5Gbit/sec. Check the CATx cable link for problems.
• Green - link speed is ok.
