Frequently Asked Questions - AT-UHD-SW-52ED Atlona

How do I connect the AT-UHD-SW-52ED to my sources and display?

Connect up to five HDMI sources to ports HDMI IN 1–5. Connect an HDMI cable from the HDMI OUT port to a display. For extended distance, connect a CAT5e/6/7 cable from the HDBaseT OUT to a compatible receiver or HDBaseT display. Optionally, connect balanced audio, IR, RS-232, and LAN for control. Use the included 48V DC power supply.

How do I switch between inputs?

Press and release the INPUT button on the front panel to cycle through HDMI inputs 1–5. Alternatively, use the built-in web server (go to Settings > Video Settings > Source) or send commands via Telnet/API. Auto-switching is enabled by default and will automatically select the last connected source.

How do I update the firmware?

You can update firmware via the web server or USB interface. For web server: log in, go to Update page, choose the firmware file, and click Upload. For USB: download firmware, disconnect power, connect USB cable to FW port, hold INPUT button while reconnecting power, release after 5 seconds, then copy firmware file to the USB UPDATE drive that appears.

How do I reset the unit to factory defaults?

There are two methods: (1) Using the web server: log in, go to Settings, and click the Reset button next to Factory Default. (2) Using the front panel: select any input from 2 to 5, then simultaneously press and hold INPUT and POWER buttons for 15 seconds until the input indicator switches to HDMI 1.

What is HDBaseT and how does it work with this switcher?

HDBaseT technology transmits HDMI audio/video, Ethernet, control (IR/RS-232), and power (PoE) over a single CAT5e/6/7 cable up to 330 ft (100 m) at 1080p. The AT-UHD-SW-52ED has a dedicated HDBaseT OUT port. Connect it to an HDBaseT receiver (e.g., AT-UHD-EX-100CE-RX) or an HDBaseT display. PoE eliminates the need for a separate power supply at the receiver.

How do I set a static IP address?

Log into the web server (default: 192.168.1.254 if DHCP fails), go to Network Setup, turn DHCP off, then enter the desired IP Address, Subnet, and Gateway. Click Save Setting. Alternatively, press and hold the INPUT button on the front panel for 15 seconds; the POWER LED will flash 4 times, and the unit will use the default static IP: 192.168.1.254 with subnet 255.255.0.0.

Can I output audio independently from the video?

Yes. The switcher provides balanced analog audio (L/R) and S/PDIF (RCA) outputs. Audio can be de-embedded from the HDMI source. Analog audio is always downmixed to PCM 2.0 stereo. S/PDIF supports PCM 2.0, Dolby Digital, and DTS. Audio muting can be set independently for HDMI, HDBaseT, and analog outputs via the web server (Settings > Audio Settings).

How do I configure the EDID for compatibility?

Log into the web server and go to the EDID page. Select an EDID preset for each input (e.g., STD for universal, ATL 2160P 2CH for 4K, etc.). You can also capture EDID from a connected display and store it in one of 8 memory locations (Output 1/2 > save to MEM_1–8). This helps ensure sources output the correct resolution and audio format.

Can I control the switcher remotely?

Yes. The unit supports multiple control methods: built-in web server (HTTP), Telnet, RS-232 (via 3-pin captive screw), and IR. The LAN port provides network access. CEC control is also available (limited compatibility). For custom integration, refer to the AT-UHD-SW-52ED API documentation.

How do I mount the AT-UHD-SW-52ED in a rack?

The switcher comes with rack-mount brackets. For a single unit, attach the short rack ear to one side and the long rack ear to the other using the provided screws. For dual side-by-side installation, attach the mounting plate to the bottom of two units, then add rack ears (sold separately). The unit can also be mounted under a flat surface (e.g., table) using the mounting plates.

* Consumer Electronics Control (CEC): Atlona has confirmed proper CEC functionality with several current models of Samsung, Panasonic, and Sony displays. However, it is not guaranteed that CEC will work with all displays. Many manufacturers do not support the CEC “off” command, and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure defined in HDMI 1.2a. It is recommended that dealers request an evaluation product from Atlona, before designing a system using the CEC protocol. If this is not possible, then other control methods will need to be considered, in order to control displays using Atlona products.
