MX-FR Series Modular Matrix Frames – User's Manual 103
Setting the Parameters
The signal type is set to DVI, the other parameters have not been changed. 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 Legend.
