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

range of products. When used with DRL synthesized radios

(DL-3400 and JSLM/RNet) a shorter 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 modem, 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.

SETUP SWITCH S101

a. To access S101 and make other 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 indicated 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.
