6221 Radio

Description...

The two-way radio telemetry package uses a programmable FM transceiver. The frequency shift
keying (FSK) radio modem is mounted on the DCP main circuit board. Modulation meets CCITT
v.32 specifications at 1200 baud. Signal lines include transmitted audio (TXA), receive audio
(RXA) and push-to-talk (PPT, active low open protector). The radio is factory-installed in the 6200
DCP and the FSK modem is installed only on systems ordered with the radio option.

The separate base station radio (P/N 6250) incorporates both the radio and modem into a single
package for use at the base station.
