VS-88FO - Kramer Protocol 2000
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 using the front panel. Reception of this code by the switcher is not valid.
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 machine name
would be (HEX codes):
7D
96
90
81 (i.e. 128
dec
+ 22
dec
for 2
nd
byte, and 128
dec
+ 16
dec
for 3
rd
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. 128
dec
+ 3
dec
for 2
nd
byte, 128
dec
+ 5
dec
for 3
rd
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. 128
dec
+ ASCII for “Y”; 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 (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 (4
th
byte) is set, then the “video” commands have universal meaning.
For example, instruction 1 (SWITCH VIDEO) will cause all units (including 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 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 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.
