MRC-565 Packet Data Radio Operations & Maintenance
where: type = INTERVAL or TIME (I or T)
time = hours:minutes:seconds
OFFSET,hh:mm:ss = time offset from specified timeframe (optional)
command = any MRC-565 command (with parameters)
command = any MRC-565 command (with parameters)
To remove command event(s) from the schedule list, enter:
SCHED,DEL,xxx
where: xxx = ALL (erases entire schedule)
or
= schedule list number (removes single scheduled event from the schedule list)
= schedule list number (removes single scheduled event from 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).
5.3.3 Setting Timeout Duration
There is one programmable time limit for the I/O port input on the MRC-565. MRC
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.

5.3.4 Defining Data Relays
The ambient noise conditions at a remote station site may sometimes be excessive and a poor
communication path to the Master Station will result particularly if the remote station is
operating in a meteor burst mode. To overcome this problem, another MRC-565 may be placed
in a nearby quiet location and used as relay station between the MRC-565 at the noisy site and its
master station. When used as a relay, the MRC-565 will concentrate the data reports it receives
from one or more neighboring remote sites and forwards the data to the Master Station.
In this mode, the MRC-565 must be defined as a Master Station. The relay will then receive
Group data reports from other MRC-565 units located in noisy or un secure locations and
repackage them and forward them to the Master Station. A relay can handle sixteen GROUP
reports. These reports can be in any combination; i.e., four groups from each of four Remote
units, one group from each of sixteen Remote units or any combination in between. Substitution
