Frequently Asked Questions - OMX-07HMHM0001 Ocean Matrix

How do I switch a specific input to a specific output?

Use the front panel: press the Output button (1-4) then press the Input button (1-4). Alternatively, use the remote control by pressing the desired Output then Input. You can also use the web GUI or RS232 commands.

Can I use this matrix with mixed 4K and 1080p displays?

Yes, the OMX-07HMHM0001 supports downscaling. It can simultaneously display 4K content to a 4K monitor and downscale the same content to 1080p for a 1080p monitor.

How do I extract audio from HDMI to analog or SPDIF?

Go to the Audio menu on the front panel. Select De-Embed, then choose the output (1-4 or All). Turn On or Off the audio extraction for that output. When on, the analog and SPDIF outputs will carry the audio from the selected HDMI input.

How do I set up EDID for an input?

From the main menu, navigate to EDID. Select the input (1-4 or All). Choose a default EDID (e.g., Default1: 4K60 444 with HDR) or a user EDID. The selected EDID will be applied to that input for optimal compatibility.

How do I control the matrix via RS232?

Connect the RS232 cable. Use a serial terminal with settings: 115200 baud (default), 8 data bits, no parity, 1 stop bit. Commands start with # and include a space between command head, parameter, and target. For example, to switch input 1 to output 1, send #sw i1 o1 (refer to command list in manual).

How do I access the web GUI?

Connect the matrix to your network via Ethernet. Set your computer to a static IP in the same subnet (e.g., 192.168.1.x). Open a browser and enter the default IP: 192.168.1.168. Login with username admin and password 123456. You can then control switching, audio, EDID, network, and system settings.

How do I use presets?

From the front panel, navigate to Preset menu. You can Save the current video, audio, EDID, and system settings as a preset (1-8). To Call (recall) a preset, select it and press Enter. To Clear a preset, choose it and confirm.

What does the LOCK button do?

The LOCK button on the front panel locks all other buttons to prevent accidental changes. Press and hold LOCK to lock; repeat to unlock. When locked, the LCD will indicate the lock status.

How do I perform a factory reset?

Go to Setup > Factory. Choose Common to reset video, audio, EDID, and settings (but not network or presets). Choose All to reset everything including network, presets, and device name. Confirm with Yes.

What should I do if there is no video output?

First, check all HDMI connections and ensure source devices are powered on. Verify the power supply is connected and the matrix is on. Check EDID settings (try Default1). If using a 4K source with a 1080p display, ensure downscaling is active. Try a factory reset if needed.
