4.3.5 Sending Canned Messages
The MCC-545C may be placed into a canned message mode for automatic transmission of a
repetitive message to an assigned neighboring station. In the canned message mode no more
than 25 messages may be placed into the Tx Queue at one time. You may either send an edited
text message or a message that is randomly generated from the alphabet.
To enter a canned message generated from the alphabet, enter:
CANMSG,id,msg length{,min.queue depth}
where “id” is the neighboring station ID, the message length is from 1 to 3000 characters and the
queue depth is from 1 to 25. The default queue depth is 5. Additional canned messages will be
injected if the number of canned messages in the queue falls below the minimum queue depth.
To enter an edited canned message, enter:
CANMSG,id
where “id” is the neighboring station’s ID. After composing your message press the [ESC] key.
The MCC-545C will automatically route up to 25 copies of the canned message to the
destination station.
Each canned message will be acknowledged by the selected neighboring station. No end-to-end
acknowledgement will be received.
To terminate the mode, enter:
CANMSG OFF,id
Canned messages are normally not printed at destination station. To print canned messages as
they are received, enter:
CANMSG MODE,PRINT
To turn off the print mode, enter:
CANMSG MODE,NO PRINT
4.3.6 Receiving Messages
When a new message is received it is announced by the following display:
hh:mm:ss RECEIVING name:sss TXT sss/nn FROM name ROUTED TO: name
The MCC-545C then generates an ACK of the message packet and transmits the ACK to the
neighbor from whom the message was received:
