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 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. 128
dec
+ 22
dec
for 2nd byte, and 128
dec
+ 16
dec
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. 128
dec
+ 3
dec
for 2nd byte, 128
dec
+ 5
dec
for 3rd byte).
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.
