VM-4H2 - Overview
To select the operation mode, set the DIP-switches as follows:
Programming
mode
HDCP Input
(MAC mode)
Force RGB
Lock Default
EDID
DIP
1
2
3
4
OFF (up)
Normal mode
HDCP enabled
Force RGB
EDID not locked
ON (down) Enable programming HDCP disabled
Normal mode
EDID locked
The
VM-4H2
toggles between “Normal” and “Force RGB” modes.
In “Force RGB” mode, the read EDID is rewritten to identify only RGB support.
•
To force RGB, set DIP 3 OFF (up)
•
After setting Force RGB mode you must re-acquire the EDID to update the
Force RGB change
Powering on the device identifies the mode as follows:
•
In “Normal mode” (meaning no forcing RGB), the LEDs flash once
•
In “Force RGB mode”, the LEDS flash four times.
Note: Force RGB modifies the EDID saved on the input to not support YUV format.
In case of a pink display, use the Force RGB mode.

LED Indications
The input and output LEDs turn on only when there is an input signal and an active
output device connected.
Flashing LEDs indicate the following states:

Flashes twice quickly, repeatedly
HDCP signal on input.
Output device does not support HDCP
Flashes slowly, repeatedly

Output device does not support HDCP
and has invalid EDID
