Message Tag
The number set as a Message Tag will be transmitted at the start of each data string. It will be
passed to the host at the receiving station to indicate the source of the data.
The function is disabled by setting the Message Tag to 0000
TX Priority
With TX Priority set N the modem will monitor the RF Carrier frequency before transmitting.
This is to prevent data collisions. If it is being used then a random number delay timer is
started and the transmission is attempted again when this times out.
If the TX Priority is set to Y then data will be immediately transmitted regardless of whether
there is an RF Carrier detected or not. This is used in environments with large amounts of RF
emissions.
FEC
The Forward Error Correction algorithm puts redundant bytes into the data string so that it can
correct the data at the receiving modem.
Packetise Data
The Packetised Data option is set to Y and the ID number of the destination modem is set in
the Set Repeater Path. This could be a single ID number for a back to back system or multiple
