Frequently Asked Questions - AT-UHD-SW-51 Atlona

How do I change the EDID for a specific input?

Log into the web server, go to the EDID page, and select a preset from the drop-down list next to the desired input. You can also store a custom EDID by capturing it from the display using the memory slots (MEM_1 to MEM_8).

What is the default IP address of the AT-UHD-SW-51?

By default, the unit uses DHCP. If no DHCP server is found, it falls back to Auto IP (169.254.x.x). The static IP (when enabled) defaults to 192.168.1.254 with subnet 255.255.0.0 and gateway 192.168.1.1.

How can I reset the switcher to factory defaults?

You can reset via the web server (Settings page > Factory Reset) or via front panel: power on, select any input from 2-5, then press and hold both INPUT and POWER for 15 seconds until the input indicator switches to HDMI 1.

Does the AT-UHD-SW-51 support 4K at 60Hz?

Yes, it supports 4K/UHD at 60 Hz with 4:2:0 chroma subsampling (8-bit). Higher resolutions up to 4096x2160 are supported at reduced refresh rates or with 4:2:0 only.

How do I update the firmware?

Download the firmware from atlona.com. Update via the web server (Update page) or using a USB mini-B cable: disconnect power, hold INPUT while reconnecting power, then copy the firmware file to the USB UPDATE drive that appears.

Can I control the switcher via RS-232?

Yes, the unit has a 3-pin captive screw RS-232 port. It can be used for direct control or bidirectional pass-through. Default baud rate settings are configurable via the web server.

How do I enable or disable auto-switching?

Log into the web server, go to Settings, and set the Auto Switch drop-down to On (enable) or Off (disable). Auto-switching is enabled by default.

What audio formats can be de-embedded?

The analog audio output (RCA) outputs downmixed 2-channel PCM. The S/PDIF output can carry PCM 2.0, Dolby Digital, and DTS Digital Surround (up to 5.1). ARC is supported from the HDMI display to S/PDIF.

What is the warranty period?

New hardware products purchased after June 1, 2013, have a 10-year limited warranty. For products purchased before that date, the warranty is 3 years. Refurbished/discontinued products have a 3-year warranty.

How do I mount the AT-UHD-SW-51 in a rack?

Attach the included rack ears using the screws on the sides. For a single unit, use one short and one long ear. For two units side-by-side, attach the mounting plate to the bottom, then install rack ears on the outer sides.

IP Configuration

The AT-UHD-SW-51 is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available), will automatically assign an IP address to the unit. If the AT-UHD-SW-51 is unable to detect a DHCP server within 15 seconds, then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx.

Use an IP scanner, along with the MAC address on the bottom of the unit, to identify the unit on the network. If a static IP address is desired, the unit can be switched to static IP mode. The default static IP address is 192.168.1.254.

Setting the IP Address using the Web Server

The AT-UHD-SW-51 can be set to either DHCP or static IP mode. If changing the IP mode through the built-in web server, the IP address of the AT-UHD-SW-51 must be known. By default, the AT-UHD-SW-51 is set to DHCP mode and will automatically be assigned an IP address by a DHCP server. Refer to the Changing the Network IP Mode (page 18) for more information.

Auto IP (APIPA) Mode

If the AT-UHD-SW-51 is unable to detect a DHCP server within 15 seconds, then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx. If this occurs, connect the AT-UHD-SW-51 to a computer running Microsoft Windows® and follow the procedure below.

1. Click Start > Settings > Control Panel > Network and Sharing Center.
2. Click Change adapter settings.
3. Right-click on the adapter that is used to establish a wired connection to the network, and select Properties from the context menu.
4. Under the Ethernet Properties dialog box, select Internet Protocol Version 4 and then click the Properties button.
5. Click the Use the following IP address radio button.

IMPORTANT: Before continuing, write down the current IP settings in order to restore them, later. If Obtain an IP address automatically and Obtain DNS server automatically are selected, then this step is not required.

1. Enter the desired static IP address or the IP address provided by the network administrator. If the PC does not require Internet access or if a statically-assigned IP address is being used, then an IP address of 169.254.xxx.xxx can be entered.
2. Set the subnet mask to 255.255.0.0.
3. Click the OK button then close all Control Panel windows.

EDID Management

Before a source can send picture and sound to a display device, the source reads the EDID (Extended Display Identification Data) structure, which is stored in the display. The EDID contains information about what type of video and audio formats are supported by the display. The AT-UHD-SW-51 can use either the downstream EDID (from the display/sink), and stored, or use a built-in EDID preset.

• EDID Presets
- Storing EDID Data
