Frequently Asked Questions - AT-OME-RX31 Atlona

How do I change the IP mode on the AT-OME-RX31?

Press and hold the IP MODE button on the front panel for 5 seconds until the LED blinks. It will blink 2 times for Static IP mode, then 4 times for DHCP mode. The default static IP is 192.168.1.254 with subnet 255.255.0.0 and gateway 192.168.1.1.

How can I access the webGUI?

Connect an Ethernet cable from the LAN port to your network. Press the DEVICE IP button on the front panel to display the IP address on the connected display. Open a web browser and enter that IP address. Log in with username admin and password Atlona.

How do I control my display via CEC?

In the webGUI, go to Display > CEC. You can send Power On/Off or Volume commands. Also enable Display Auto Power under System Settings to automatically turn the display on/off based on signal presence.

What are the mounting options?

The unit includes two mounting brackets and four screws. Remove the top case screws on the sides, align the brackets, and secure them with the same screws. Then mount the unit using the oval holes on the brackets. Brackets can be inverted for under-table mounting.

How do I reset the unit to factory defaults?

Press and hold the RESET button on the front panel for 5 seconds until the LED blinks. This will reset all settings, including IP mode, back to factory defaults.

Can I update the firmware?

Yes. Download the latest firmware from https://atlona.com/product/AT-OME-RX31/. In the webGUI, go to System > Firmware update, click Choose File to select the firmware file, then click Update.

How do I use the trigger I/O for occupancy sensing?

Connect a voltage-controlled device (e.g., occupancy sensor) to the TRIGGER I/O port using the included 4-pin captive screw. Voltage range is 3 to 30 V DC. The unit can wake from standby or power the display when occupancy is detected. Configure in webGUI under System > Trigger.

How do I output analog audio?

Connect an audio DSP or amplifier to the AUDIO OUT port using the provided 5-pin captive screw connector. The output supports balanced/unbalanced stereo. For unbalanced, jumper the negative and ground pins. Audio levels and EQ can be adjusted in the webGUI under Audio.

What EDID settings are available?

In the webGUI, go to EDID. You can select from default (highest common resolution), 4 internal EDIDs, or a previously saved EDID. To save an EDID from the output, select the output memory slot and click Save to make it available.

How do I test HDBaseT cable quality?

In the webGUI, go to HDBT. Select the HDBaseT input to test, then click Start. The test will display TX/RX version, TMDS clock, cable length, video BER, and per-pair cable quality. Pass/Fail results help diagnose cable issues.
