NOTE: It is very important to use attenuation between all units in the

test setup. The amount of attenuation required will depend on

the number of units being tested and the desired signal strength

(RSSI) at each transceiver during the test. In no case should a

signal greater than –30 dBm be applied to any transceiver in

the test setup. A transmit RF power output level of +20 dBm is

recommended. (See “Radio Conﬁguration Menu” on

Page 40.)

2.3 STEP 2—MEASURE & CONNECT

DC POWER

The power applied to transceivers must be within 6–30 Vdc and be

capable of continuously providing a minimum of 11 Watts. (Typical

power consumption is: 800 mA @ 13.8 Vdc (AP) and 600mA @13.8

Vdc (Remote). A power connector with screw-terminals is provided

with each unit. Strip the wire leads to 6 mm (0.25"). Be sure to observe

proper polarity as shown in Figure 2-5 with the positive lead (+) on the

left.

NOTE: It will take about 30 seconds for the AP transceiver to power

up and be ready for operation. The Remote requires approxi-

mately 5 seconds.

The transceiver must be used only with nega-

tive-ground systems. Make sure the polarity of the

power source is correct. The unit is protected from

reverse polarity by an internal diode and fuse.
