IMPORTANT
The MCC-545C 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 higher schedule number).
4.2.7 Setting Timeout Duration
There is one programmable time limit for the I/O port input on the MCC-545C. MCC
recommends using the pre-programmed default timeout parameter. If you choose to change the
timeout the time limits may be set by entering the number of seconds, from 0 to 32767. Enter a 0
to turn off the time limit.
Command Description
STT,secs The Set Teleprinter Timeout command sets the time limit for characters at the
maintenance terminal. 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 frequency synthesized system:
SYNTH,ON
You can then display/set the TX and RX frequencies using the following command:
FREQ{UENCIES{,aaaa,bbbb}}
where: aaaa = Tx Frequency (e.g., 4053 for 40.53 MHz)
bbbb = Rx Frequency (e.g., 4153 for 41.53 MHz)
