DESCRIPTION
The R.F. Solutions low cost Wireless Modem provides a reliable serial data communications link that can be
used for many data communications applications. The RF Modem is very simple to use and provides an
RS232 ‘invisible link’ up to 9600 baud.
Each Modem may be configured to be either a ‘Master’ or ‘Slave’ to be used in a wireless network. Up to 127
‘slaves’ may be controlled by a single ‘Master’ Modem.
Packetising and encrypting the data as well as error checking with full acknowledgement for all data
transmitted achieve highly reliable communication.
The RF Modem is supplied with an RS232 cable to connect the host and requires only a 9-12Vdc power
supply.
