Frequently Asked Questions - AT-HDR-SW-52 Atlona

How do I enable Auto Switching on the AT-HDR-SW-52?

Auto Switching is available only in Mirrored mode. Log in to the web server, go to A/V Settings, set Switching Mode to Mirrored, then toggle Auto Switch mode to ON.

What is the difference between Mirrored and Matrix modes?

In Mirrored mode, the same source is routed to both HDMI outputs. In Matrix mode, each output can independently select any input. Auto Switching is only available in Mirrored mode; in Matrix mode, analog audio follows HDMI Output 2.

How can I downscale 4K content to 1080p?

Enable the Scaler feature for each HDMI output in the web server under A/V Settings > Scaler. Set the toggle to ON. Note that the scaler only downscales resolution, not frame rate, and HDR formats cannot be downscaled.

What audio formats are supported for de-embedding via the analog L/R output?

The L/R output supports de-embedding of two-channel LPCM audio only. Balanced or unbalanced wiring is possible using the included 5-pin captive screw connector.

How do I set a static IP address?

You can set a static IP via the web server: go to System, toggle IP Mode to STATIC IP, enter IP, Netmask, and Gateway, then click Save. Alternatively, use RS-232/Telnet with the IPStatic command.

Can I lock the front panel buttons?

Yes. In the web server under System, click the Lock toggle to LOCK. This prevents accidental button presses. To unlock, toggle back to UNLOCK.

How do I capture and store a display's EDID?

Connect the display to an HDMI output. In the web server under EDID, go to EDID Saved, select the corresponding output from the drop-down, and click Save. The captured EDID appears in the input EDID lists.

What are the default login credentials for the web server?

The first time you access the web server, you must register a username and password. The password must be at least 8 characters with one uppercase, one lowercase, and one number. After registration, use those credentials to log in.

How do I perform a factory reset?

Two methods: via web server, go to System and click Factory Default; or via front panel, press and hold both POWER and INPUT buttons for 15 seconds until LEDs turn on then off.

Can I update the firmware using a USB connection?

IP Configuration

The AT-HDR-SW-52 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-HDR-SW-52 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/16. If this occurs, refer to Automatic Private IP Addressing (APIPA) Mode (page 14).

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.

NOTE: When switching between DHCP and static IP mode, the AT-HDR-SW-52 will retain the last assigned IP address until it is changed manually (static IP mode) or assigned a new IP address by the DHCP server.

Using the Front Panel

1. Make sure the AT-HDR-SW-52 is powered.
2. Connect an Ethernet cable between the LAN port of the AT-HDR-SW-52 and the Local Area Network (LAN).
3. Press and hold the POWER button for approximately 15 seconds. Release the POWER button once all the front-panel LED indicators begin to flash. The number of flashes will indicate the currently selected IP mode. Refer to the table, below.

Device Operation

Notes on Scaling

The following section provides important information about how the AT-HDR-SW-52 processes 4K (UHD) video signals.

• The HDMI OUT ports support up to 4K @ 60 Hz, 12-bit, with HDR.
- If the source is 4K, and the output port is connected to a 1080p (not 4K-capable) display, then the output will be down-scaled as follows:

Input Output
4K @ 24 Hz 1080p @ 24 Hz
4K @ 30 Hz 1080p @ 30 Hz
4K @ 60 Hz, 4:2:0 1080p @ 60 Hz, YUV/RGB 4:4:4

• HDR / Dolby Vision / HLG formats cannot be downscaled to 1080p.

- The internal scaler will be bypassed if the connected display supports the resolution and timing information from the source device.

Audio Management

The AT-HDR-SW-52 provides volume control and independent audio muting. Audio muting can be controlled on the L/R and HDMI OUT ports. To de-embed the source audio to the L/R port, connect the included 5-pin captive screw connector to the L/R port. De-embedding audio is restricted to two-channel Linear PCM formats.

EDID Management

Before a source can send picture and sound to a display device, the source reads the EDID (Extended Display Identification Data) stored in the display. The EDID contains information about what type of video and audio formats are supported by the display. The AT-HDR-SW-52 can use either the downstream EDID (from the display/sink) or use a built-in EDID preset. EDID data can also be stored in any of eight EDID presets. This section will cover each of the following topics:

• Using the Downstream EDID
• EDID Presets
- Storing EDID Data

Using the Downstream EDID

By default, the AT-HDR-SW-52 will read the EDID from the display device. The term “downstream” is used to describe any device that receives a signal from another device. For example, if a Blu-ray player is connected to a display, the display is said to be “downstream” of the Blu-ray player.
