Assigning a Device Address (ID Mode)

You can use the ID Pushbutton in conjunction with the ID (Identify) Mode feature in 

NetLinx Studio. A momentary press of the ID Pushbutton assigns a device address to 

the switcher (which must be bound to the Master). You must first place the device in ID 

Mode in NetLinx Studio or the momentary press will be ignored.

NOTE: The latest version of NetLinx Studio is available to download and install from 

www.amx.com. Refer to the NetLinx Studio online help for instructions on using the 

application.

Perform these steps to assign a device address:
1.

Check to be sure DIP switch #3 on the switcher is set to ON.

2.

In NetLinx Studio’s OnLine Tree, select the Master to which the switcher is bound.

3.

From the Diagnostic menu, select 

Device Addressing

. The Device Addressing 

dialog box opens.

4.

In the ID Mode section, enter the Device and System numbers that you want 

assigned to the device in the appropriate text boxes.

5.

Click 

Start Identify Mode

 to place the named system in ID Mode. The button 

changes to “Cancel Identify Mode” (click to cancel ID Mode). The text box below 

the button displays a “Waiting...Press Cancel to Quit” message.

NOTE: When in ID Mode, the entire system is put on hold while it waits for an event from 

any NetLinx device in the named system (e.g., pressing the ID Pushbutton on the 

switcher). The device that generates the first event is the device that will be “identified.”

6.

Briefly press and release the ID Pushbutton on the switcher. The switcher will 

exhibit the following behavior:

• Respond with an ID Mode address response.
• Report its old address offline.
• Report its new address online.

The Online Tree will refresh to display the new device address for the switcher.

NOTE: NetLinx Studio (v3.3 or later) provides the ability to auto-increment IP Addresses 

and Hostnames as well as Device and System Numbers. Refer to the NetLinx Studio online 

help for details.

Restore the Factory Firmware Image and Factory Default Parameters

During power up

 – if you hold the ID Pushbutton until the STATUS and LINK/ACT LEDs 

toggle back and forth in unison approximately 30 times (10 slow, 20 fast) and then 

release the pushbutton when the LEDs turn solid, the switcher’s factory firmware image 

will be restored. This procedure affects both the firmware version and the parameters.
Perform these steps to restore the factory firmware image and factory default 

parameters:
1.

Press and hold the ID Pushbutton while plugging in the power connector. Start 

counting when the STATUS and LINK/ACT LEDs begin to flash in unison, not when 

the power connector is inserted.

2.

After the LEDs complete the following sequence, release the ID Pushbutton:

• Once the switcher has started booting up, all LEDs flash in unison at the rate of 

once per second.

• After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.
• After 10 seconds of flashing at the increased rate, all LEDs turn on solid.

3.

Upon release of the ID Pushbutton, the switcher executes the following actions:

• Restores itself to its factory firmware image.
• Resets to factory default parameters.

4.

Once all actions in Step 3 are completed, the LEDs all turn off, indicating the 

switcher is ready to reboot.

The switcher automatically reboots to complete the process.

Important Twisted Pair Cabling Requirements and Recommendations

The following requirements and recommendations apply to cabling DXLink (RJ-45) 

connectors:

• DXLink cable runs require shielded category cable (STP) of Cat6 (or better).
• DXLink twisted pair cable runs for DXLink equipment shall only be run within a 

common building.*

• DXLink delivers 10.2 Gb/s throughput over shielded category cable. Based on this 

bandwidth requirement, we recommend following industry standard practices 

designed for 10 Gigabit Ethernet when designing and installing the cable 

infrastructure.

• The cables should be no longer than necessary to reach the end-points. We 

recommend terminating the cable to the actual distance required rather than 

leaving any excess cable in a service loop.

For more details and helpful cabling information, reference the white paper titled 

"Cabling for Success with DXLink" available at 

www.amx.com

 or contact your AMX 

representative.
* "Common building" is defined as: Where the walls of the structure(s) are physically 

connected and the structure(s) share a single ground reference.
