TRANSMIT OUTPUT LEVEL
The transmit carrier level to the transceiver is factory preset
for 400 mVrms. This input level is required by a Dataradio
transceiver connected to the modem. To change the factory
input level, follow steps d through g:
d. If necessary, remove the modem board from the housing
as described in Step a.
e. Configure the telemetry equipment connected to the RS-
232 jack to transmit a continuous data signal. If no
equipment is connected to the jack, configure S101 with
switches 1 and 7 ON. Then move switch 6 to ON to key-up
the modem. The modem will transmit a continuous
alternating space/mark tone from U230.

f. Monitor the AC voltage at TP400, J102. Adjust R400 for
400 mVrms if using a DRL telemetry transceiver. If
another transceiver is used, adjust R400 as required. J103
pin 5 has a resistor that will drop the Tx output level to
40 mVrms when connected to the DRL JSLM / RNet.
g. Re-install the modem board in the housing.
3282 LEDS
The 3282 has 2 LEDs (CR220) that are visible through the
adjustment hole in the case closest to the 10 pin connector.
One LED will flash green whenever the modem has power
and the microcontroller U220 is operating correctly. The
other red LED will be solid red whenever the modem is
transmitting.
