timeout does not apply.
3. To set the analog diversity delay:
Command Response
TR X.XXXXXXXXX[PASSCODE]
(valid passcode and argument)
DELAY: X.XXXXXXXXX
(invalid passcode)
[no error message is issued]
In the above table:
X.XXXXXXXXX
= the delay time or ?. Acceptable values are
0.000015625 to 8.192 for the 8-second board and
0.000015625 to 16.384 for the 16-second board
(10 total digits) in increments of 0.000015625
?
returns the current delay time.
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 8600 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 8600 when the on-air transmission chain is swapped.
•
If a non-existent control value, and/or an invalid passcode is entered, the 8600
will ignore the command.
•
You can apply this command anytime after the 8600 boots up. The 30-minute
timeout does not apply.
4. To change the polarity of the analog FM processing’s output:
Command Response
FM XXXXXXXX[PASSCODE]
(valid passcode and argument)
FM POLARITY is set to XXXXXXXX
(invalid passcode)
[no error message is issued]
In the above table:
XXXXXXXX
=
POSITIVE, NEGATIVE, OR ?
;
?
returns the current polarity
PASSCODE = ANY VALID PASSCODE
.

For an explanation of why this can be useful, see step 8 on page 2-29).
•
If a non-existent control value and/or an invalid passcode is entered, the 8600
will ignore the command.
