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.
