NOTES on the above table:
NOTE 1
- When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is
sent to the switchers, it will reset according to the present power-down settings.
NOTE 2
- These are bi-directional definitions. That is, if the switcher receives the code, it will perform the
instruction; and if the instruction is performed (due to a keystroke operation on the front panel), then these codes are
sent. For example, if the HEX code
01
85
88
83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to
output 7 via the front panel keypad, then the switcher will send to the PC:
41
81
87
83
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher
replies by sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION
bit is set high).
NOTE 3
- SETUP # 0 is the present setting. SETUP # 1 to SETUP # 15 is the settings saved in the switcher's memory,
(i.e. those used for Store and Recall).
NOTE 4
- The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent
are returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11
are as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is
breakaway setting, then the reply to the HEX code
0B
80
80
85
would be
4B
80
81
85
NOTE 6
– If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with
OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid
instruction code).
If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this
function, even for the case that the function is not defined. For example, for a video switcher which always switches
during the VIS of input #1, (and its VIS setting cannot be programmed otherwise), the reply to the HEX code
4A
FE
80
81 (i.e. request VIS setting, with INPUT set as 126
dec
)
Would be
4A
FE
81
81 (i.e. VIS setting = 3, which is defined as VIS from input #1).
NOTE 7
– Setting OUTPUT to 0 will return the VIS source setting as defined in instruction #7.
NOTE 8
- The reply to the "REQUEST WHETHER SETUP IS DEFINED" is as in TYPE 3 above, except that here
the OUTPUT is assigned with the value 0 if the setup is not defined; or 1 if it is defined.
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 15, 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.
