When locking an unlocked output, the specified password is recorded by the router as the
lock password for that output. When unlocking a locked output, the specified password is
compared by the router to the lock password for the output. If they match, or if the
specified password is the administrator password, the output is unlocked, else it remains
locked. Attempting to lock an already-locked output, or unlock an already-unlocked
output, has no effect on the lock state of that output.
Whenever a take is done, the router checks to see if the specified output for the take has
been locked. If so, the current password of the control port that sent the take request (as
set with the “K” command) is compared to the outputs lock password. If they match, the
take
is allowed, but if not, the take has no effect. The administrator password may NOT
be used in lieu of the outputs lock password to do a take,
so if a controlling device sends
the administrator password in a “K” command, that will not permit the device to reroute
locked outputs (but it can use the administrator password to unlock locked outputs using
the “B” command).
Output lockouts apply on all levels. On virtual-mapped routers, a level may be left out of a
lockout by making sure the level is unmapped for the destination being locked.
As with all router configuration parameters, the output lockout data is stored in non-
volatile storage and thus is retained across router power-ups. When a router is first
initialized at the factory, all outputs are set to be unlocked.
This command provides the same functionality as the “G OUTPUT_LOCK” command.
This command, which was added at router software version V5.06, is preferred over that
command. Note that the output lock version number is not present in this command.
Since output lock status changes frequently, it is not really useful to cache output lock
status for outputs, so the output lock version number is not really useful.
For example, to request whether or not output 21 is locked:
** B21,0,0 !!
The response might be:
** B21,0,0 OK !!
indicating that output 21 is NOT locked. Or, the response might be:
** B21,6741,1 OK !!
indicating that output 21 is locked with password 6741. To clear this lockout:
** B21,6741,0 !!
To lock output 96 using password 439:
** B96,439,1 !!
If successful, the response would be:
** B96,439,1 OK !!
If output 122 becomes locked using password 235, the following change report would be
sent by the router:
** B122,235,1 !!
