PASSCODE = ANY VALID PASSCODE
.

This command is useful when a station has two transmission chains (typically
main and backup) that require different diversity delay settings. We recommend
first using 5518 PC Remote to set the correct delays for the main and backup
chains. When you have found the correct delay for each transmission chain, write
down the delay times that PC Remote displays. Then program these into “main”
and “standby” batch files that, when executed, send the appropriate TR com-
mand to the 5518 when the on-air transmission chain is swapped.

If a non-existent control value, and/or an invalid passcode is entered, the 5518
will ignore the command.
4. To select the analog or digital input as the audio source:
Note: When the input is set to
D
IGITAL and no valid digital signal is present at the
input, the setting of the
DI A
NALOG
F
ALLBACK control will determine whether the
Optimod automatically switches to its analog input. See step 27 on page 2-20.
Command Response
IN X[PASSCODE]
(valid passcode and argument)
INPUT: [ANALOG, DIGITAL, DIGITAL
J17] (for each output)
(invalid passcode)
[no error message is issued]
IN [PASSCODE]?

Returns active Input.
In the above table:
X = A, D, J17
where A = analog input, D = digital input, and J17 = Digital
J.17.
PASSCODE = ANY VALID PASSCODE
.

? returns the active input setting.

If a non-existent control value and/or an invalid passcode is entered, the 5518
will ignore the command.
