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 resets according to the present power-down settings.
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it performs 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) switches input 5 to output 8. If the user switched
input 1 to output 7 via the front panel keypad, then the switcher sends HEX codes:
41
81 87 83
to the PC.
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 and higher are 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 HEX codes
4B
80 81 85
NOTE 5 – For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte.
Similarly, for the OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte.
Note also, that on some machines the sync source is not software selectable, but is selected using
switches, jumpers, etc!
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 returns 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
0A
FE 80 81 (i.e. request VIS setting, with INPUT set as 126dec)
would be HEX codes
4A
FE 81 81 (i.e. VIS setting = 1, which is defined as VIS from input #1).
NOTE 7 – Setting OUTPUT to 0 returns the VIS source setting as defined in instruction #7. Setting to 1
returns the input # or output # of the sync source (for the case where the VIS source is set as 6 or as 7 in
instruction #7). Setting to 2 returns the vertical sync frequency (0 for no input sync, 50 for PAL, 60 for
NTSC, 127 for error).
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.
