KRAMER: SIMPLE CREATIVE TECHNOLOGY
Kramer Protocol 2000
38
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 11
– For machines where the video and / or audio parameter is programmable.
NOTE 12
– Under normal conditions, the machine's present status is saved each time a change is made. The "power-down"
save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save function is set.
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 (i.e. request the number of outputs)
would be HEX codes
7E
82
90
82 i.e. 16 outputs
NOTE 15
– When the OVR bit (4th byte) is set, then the “video” commands have universal meaning. For example,
instruction 1 (SWITCH VIDEO) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in
“FOLLOW” mode, it will perform any “video” instruction.
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 17
– For clean switching of RGBHV video, the “seamless switching” option may be used. The blanking period for the
transition of the RGB sources may be set in this case, in steps of 25 milliseconds.
For example, to set for 350ms blanking time (14 steps), send HEX codes
07
8E
A0
81
NOTE 18
– Delayed execution allows switching after a delay dictated by RS-232. To do this, the user sends instruction 7
with the “Set for delayed switch” option (64dec) before sending the switch command (instruction 1) or pressing via front
panel. The switch is not executed (unless timed-out) until the “Execute delayed switch” code is sent, or the “Set for delayed
switch” code is sent again. (The mode is automatically cancelled after implementation of the switch if the “execute”
command is used).
For example, to connect input 4 to output 3 after a delay, send HEX codes
07
80
C0
81
(set for delayed switch)
01
84
83
81
(switch code)
then, after the required delay, send HEX codes
07
80
C1
81
(execute delayed switch)
to implement the switch.
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.
