Addressing
Addresses can be used to route a data message to the desired destination or to separate two
parallel networks from each other. In networks with repeaters it is usually necessary to use
addresses to prevent data messages from ending up in loops formed by repeaters. In case of
setting the “Message Routing” function in use, Tx/
Rx addresses are ignored by the modem.
Modem allows the use of individual addresses both for reception and transmission. Addresses
can be switched on separately, or simultaneously, in both data transfer directions.
The radio modem contains two transmission and two reception addresses, which are knows as
the primary address and secondary address. The primary address is used whenever data from
the serial interface is transmitted. At the receiving end, the radio modem will receive using
either of the two receive addresses.
Secondary transmit address is only used in repeater applications.
Radio modems configured to function as repeaters, will repeat data messages using either the
primary or secondary address, depending upon which address was used during the reception of
the data message.
If only one address pair is needed in a network, both addresses must be set the same (TX1 = TX2
and RX1 = RX2).
It is also possible to transfer the received address onto the serial interface.
