and other operational parameters and then use the "Save" command to write them to CPM. As
soon as the parameters are entered they take effect.
CAUTION
Once the software is rebooted or is restarted due to a SW crash, power cycle, operator
BOOT, all changes will be lost unless they were previously saved in CPM.
5.4 Sending and Receiving Messages
The MRC-565 is a packet data radio and therefore enables an operator to send and receive
messages to all units within the network.
The messages may be entered from an operator terminal that is connected to the MNT PORT of
the MRC-565. There are three basic message types: (1) free-form text messages, (2) canned
messages and (3) commands. The general format for all messages is shown below:
MESSAGE, R , dest 1, dest 2, …dest n
where: R = Message priority; A is highest, Z is lowest.
dest = ID of the station(s) to which the message will be sent.
The message text is then entered and edited in the TEXT EDIT BUFFER. They are then
transferred to one or more TX QUEUE buffers for transmission to the designated destinations.
The diagram below depicts the general flow of messages within the MRC-565 software and the
various commands associated with each step in the process.
