2. 2 Part No. 004-3282-004 TRANSMIT OUTPUT LEVEL The transmit carrier level to th e transceiver is factory preset for 400 mVrms. This input level is required by a Dataradio transceiver connected to the mo dem. 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 e quipment connected to the RS- 232 jack to transmit a continuous data signal. If no equipment is connected to th e jack, configur e 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 wh enever the modem has power and the microcontroller U220 is operating correctly. The other red LED will be solid red whenever the modem is transmitting.

1. 1 Part No. 004-3282-004 DL-3282 MODEM SETUP INSTRUCTIONS INTERCONNECT CABLE INSTALLATION This modem requires a power source with an operating voltage range of 7 - 16 Vdc. Note: A transceiver may require a more restrictive operating range . * See Figures 4 and 5 for pinout details. The 3282 interfaces with user equipment through the DB- 25 RS232 connector. See Figure 1 for pinout details . DEFAULT FACTORY SETTINGS Normal Conventional Bell 202 Half Duplex Active High Squelch FSK Audio 240 ms RTS to CTS Delay 100 mS Soft Carrier Turnoff debounce time Transmit Input Level (pre-set for 400 mVrms) The factory default setting for the RTS to CTS delay time is set to the maximum delay for compatibility with a wide range of products. When used with DRL synthesized radios (DL-3400 and JSLM/RNet) a s horter delay time (30ms) may be used (refer to Tables 2 through 4 and Figure 3). Follow steps a through c under setup switch S101. RECEIVE INPUT LEVEL For proper operation of the mo dem, the carrier level from the transceiver should be 35 mVrms -1mVrms (or 99 mVp- p - 2.8 mVp-p). DRL transceivers (DL-3400) are factory adjusted to provide a data level output to the modem of 707 mVrms (or 2 V p-p). The data level output to the modem when used with the DRL JSLM/RNet is 212 mVrms + 17.5 mVrms (or 0.6 V p-p + 0.05 V p-p). ADJUSTMENTS There are two adjustments on the modem board. These adjustments have been set at the factory and may require further adjustment in the field for your application. DIP Switch S101 Transmit Level Adjust R400 Figure 2 DIP SWITCH S101 (DEFAULT SETTINGS) SETUP SWITCH S101 a. To access S101 and make othe r adjustments, remove the modem board from the housing by removing the 2 screws on the RS-232 connector, the corner screws from the op- posite end of the housing, and the top cover screw. Slide the modem board out. b. Set the switches as indicat ed in Tables 3 and 4 (0=Off, 1=On). c. Re-install the modem board in the housing unless performing adjustments described in the following two sections.
