The radio modem will
transfer all received
data to the RS-232 -
interface.
Reception addressing has
been set OFF.
The radio modem will
consider the characters of
the address as a part of the
data and will send all the
characters to the RS-232
interface.
Reception addressing has
been set ON but there is no
address in the data packet.
Data will appear on the RS-
232 interface ONLY if the
first 2 bytes of the data
match either of its own RX
address. The radio modem
will remove those 2
characters of data.
13.2.1
Connection between two points
When forming a connection between two points it is recommended that both the reception and
transmission addresses are identical in both radio modems. This is the easiest way to control
addresses and the risk caused by interference from other systems operating in the same area is
minimal.
Example: by setting all addresses of both radio modems to a value ´1234´, they will accept only
those messages which contain this address, and they will use this same value when transmitting
data.
If the channel is reserved for use only by the single network, or if the terminal devices are
responsible for addressing, it is not necessary to use addressing in the radio modems.
