Kramer Protocol
45
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the VS-
7588YC, the reply to the request to send the first suffix would be (HEX codes):
7D
D9
C3
81 (i.e. ASCII for “Y”; ASCII for “C”).
NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For example, if
six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code
3E
82
81
82 (ie. request the number of outputs)
would be HEX codes
7E
82
90
82
ie. 16 outputs
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 21, 22, 25 and 26 is sent using instruction 42 – which is sent prior to the
instruction. For example, to request the audio gain value of right input # 9, send hex codes
2A
84
80
81
and then send HEX codes
19
89
81
81.
To set MIX mode, send hex codes
2A 81 84 81
and then send HEX codes
16
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
10
83
84
81
If input 7 is detected as valid, then the unit will send HEX codes
10
87
85
81.
