Kramer Protocol 2000
29
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 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 2,
the machine sends its name. The reply is the decimal value of the INPUT and OUTPUT. For
VS-121HCA
, the reply to the
request to send the audio machine name would be (HEX codes):
7D
81
95
81 (i.e. 128
dec
+ 1
dec
for 2
nd
byte, and 128
dec
+ 15
dec
for 3rd byte).
If the request for identification is sent with the INPUT set as 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. 128
dec
+ 3
dec
for 2nd byte, 128
dec
+ 5
dec
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 the
VS-121HCA
,
the reply to the request to send the first suffix would be (HEX codes):
7D
C8
C3
81 (i.e. 128
dec
+ ASCII for “H”; 128
dec
+ 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 26
– After this instruction is sent with OUTPUT defined OFF, the unit will not send reply to the protocol commands.
In order to return to working with REPLY, this instruction must be sent with OUTPUT defined ON. In cases where there is
hardware control of the REPLY, (eg a DIP-switch to disable replying), this instruction is only valid when the hardware
REPLY is set ON.
