Operations Manual

OPERATIONS 4-9
O&M of the MCC-545B PACKET DATA RADIO
12/2000
NOTE
The scheduler ignores certain 545B commands due to their interactive nature. The MESSAGE
command is currently the only ignored command
To remove command event(s) from the schedule list:
SCHED,DEL,xxx
where: xxx = ALL (erases entire schedule)
or
= schedule list number (removes single scheduled event from schedule list)
IMPORTANT
The 545B currently supports up to 50 scheduled command events. The schedule list will be
erased if the system software re-boots (not to be confused with power failure recovery, which
will preserve the schedule list).
You can schedule several command events to trigger at the same time; however, you cannot
force one command to execute before or after another. After assigning command events to the
schedule, the order of commands displayed in the schedule list is the order in which the events
will trigger for any given trigger time (i.e., an event with a low schedule number occurs before
an event with a high schedule number).
4.2.7 Setting Timeout Duration
There is one programmable time limit for I/O port input on the 545B. MCC recommends using
the given default timeout parameter. If you choose to change the timeout, use the following
command. Time limits are set by entering the number of seconds, from 0 to 32767. Enter a 0 to
turn off the time limit.
Command Description

Default is 60 seconds (1 minute).
4.2.8 Setting Frequencies
The FREQUENCIES command is used in systems using synthesized frequencies only (see
Section 2.7.4). To enable setting frequencies, you must first enter the following command to
identify the system as a synthesized frequency system:
