KRAMER: SIMPLE CREATIVE TECHNOLOGY
Kramer Protocol
54
NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the
instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output
greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine
is being programmed via the front panel. Reception of this code by the switcher is not valid.
NOTE 10 – This code is reserved for internal use.
NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the
machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to
the request to send the audio machine name would be (HEX codes):
7D
96
90
81 (i.e. 22dec for 2nd byte, and 16dec for 3rd byte).
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version number.
Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the
decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to
send the version number would be (HEX codes):
7D
83
85
81 (i.e. 3dec for 2nd byte, 5dec for 3rd byte).
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.
