MX-FR Series Modular Matrix Frames – User's Manual 130
Timing Parameters
The system continuously measures the parameters of the signals. The answer consists of 16 data bytes
and every data byte is represented as a two-digit hexadecimal number. The parameters could be useful for
advanced debugging processes.
Supported Boards

The signal type is set to DVI, the other parameters have not been changed. The second, third, and fourth
parameters are 'x' in all cases (because of compatibility reasons). Use the 'x' character to keep the actual
value of a parameter. The response contains the new settings in the <OUT_SET> block; see the details in the
Parameters section.
Parameters
<> block
Format: G<a><b><c><d><e>
Parameter Description Parameter Values
<a> Sink is connected
0 = no attached sink device
1 = sink device is present
<b> Signal type
0 = DVI signal is transmitted
1 = HDMI signal is transmitted (no deep color)
2 = HDMI signal is transmitted (deep color, 30 bit)
3 = HDMI signal is transmitted (deep color, 36 bit)
<c> Signal validity
0 = No valid signal is routed to the port
1 = Valid video signal is present
<d> HDCP state
0 = HDCP encryption is disabled
1 = HDCP encryption is active
<e> Hotplug detection
0 = Hotplug detect signal is low
1 = Hotplug detect signal is high
Example: G11101 #hdcp
Sink device is attached and HDMI signal is routed to the port. HDCP is disabled and hotplug is detected.
