F.3 INCORPORATING THE RF300 AND

THE RF95A

The RF300 is similar to the RF100 and RF200
radios. The 100/200 series uses a Crystal to
generate the carrier frequency and were
manufactured by EF Johnson. The RF300
radios digitally synthesize the carrier frequency
and are manufactured by Dataradio COR Ltd.
(DRL). The DRL radio is modified to work with
the RF95A. RF300 radios can have their carrier
frequency changed using a PC, the RS232 port
and the appropriate software. There are limits
to how far the frequency can be changed.
Contact CSI to purchase a copy of the software.
See Table F-2 for more information.

The RF95A is very similar to the RF95. The
RF95A strobes power to the radio. This is done
to conserve battery life. The RF300 radios will
work with the RF95 but will use three times
more quiescent current without the power
strobe, approximately 100 mA. The RF95A
also uses different communications techniques
which benefit the RF300 radios. A RF95A will
work anywhere the RF95 works provided the
correct cable is used, Table F-3.
