CEN-GWEXERs are a two-way radiofrequency (RF) transceivers that allow Crestron infinetEX and Extended Range wireless devices to communicate with the control processor over Ethernet. They are for Crestron wireless systems what DIN-CENCN-2s are for wired Cresnet systems.

For SHOWRUNNER™ installations, the IP address of the CEN-GWEXER does not matter as long as it is in the same range as the processor and does not conflict with any other devices on the network. Instead, CEN-GWEXERs are identified to the processor via their IP-ID. Note that which infinetEX devices are landed at which CEN-GWEXER matters, and if devices are moved between CEN-GWEXERs then the configuration will need to be updated (see below). Chief Integrations typically provides an SRTakeoff.xlsx spreadsheet with an IP Table tab that lists all the CEN-GWEXER IP-IDs in the program. If no takeoff is provided, then the processor's IP table can be checked by running the ipt -t command from the processor after the configuration is loaded. DIN-CENCN-2's will typically have IP-IDs in the "Cx" range.

top light will blink slowly a few times and then hold solid or start blinking rapidly
if rapid blinking, cancel acquire and make sure that rf gateway is in acquire mode and device is in range then repeat to put device into acquire mode

Moving/Removing Devices (Unacquiring Devices)

When a wireless Crestron device is acquired to a new gateway using the typical acquiring process described above, it will automatically forget the previously connected gateway. The gateway itself, however, must manually "forget" the previously connected device before a newly acquired and addressed device will function correctly. This is necessary whether the originally connected device is moved or if the originally corrected device has failed and is being replaced. 

To unacquire a device from a gateway, it is necessary to run the below commands, replacing "[TSID]" with either the 4-byte hexadecimal TSID of a single device or "all" to forget all previously acquired devices. Devices do not need to be online in order to be acquired (e.g., a failed device can still be unacquired using this method). While only one of these commands needs to be run per device, it is not documented which command (ending in "0" or "1") is required for each model, so it is generally advisable to run both commands for each device to be unacquired:

• unacquirebytsid [TSID] 0
• unacquirebytsid [TSID] 1

Once all of the necessary TSIDs have been unacquired, use the reboot command to reboot the gateway and complete the unacquire process.
