VP-4x4K - Kramer Protocol

NOTE 16 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the

OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte.

The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.

NOTE 24 – Further information needed in instructions 22 and 25, is sent using instruction 42 – which is sent prior to the

instruction. For example, to request the audio gain value of output # 9, send hex codes

and then send HEX codes

81.

To set input gain change mode, send hex codes

2A 80 80 81

and then send HEX code

NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a

change in the state of an input (in real-time).

For example, if input 3 is detected as invalid, the unit will send the HEX codes

If input 7 is detected as valid, then the unit will send HEX codes
