STEP 1—CONNECT THE ANTENNA PORTS
Figure 2-3
is a drawing of a tabletop arrangement. Connect the antenna
ports of each transceiver as shown through attenuators and an RF power
divider. This provides for stable communications between each radio,
while preventing interference to nearby electronic equipment.

Figure 2-3. Typical Setup for Tabletop Radio Testing
NOTE:
It is very important to use attenuation between radios in the test
setup. The amount of attenuation required depends on the
number of radios being tested and the desired signal strength
(Received Signal Strength Indicator, or 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 (100 mW) is
recommended. This can be set via the radio menu (
Main Menu >
Radio Configuration > RF Output Power Setpoint
).
STEP 2—MEASURE AND CONNECT DC POWER
The power applied to transceivers (AP and Remotes) must be within
6–30 Vdc and be capable of continuously providing a minimum of 11 W
(typical power consumption is 800 mA at 13.8 Vdc for the AP and
600 mA at 13.8 Vdc for Remotes).
A power connector with screw terminals is provided with each radio.
Strip the wire leads to 6 mm (0.25 in.). Observe proper polarity, as
shown in
Figure 2-4 on Page 20
, with the positive lead (

) on the left.
NOTE:
It takes about 30 sec for the AP transceiver to power up and be
ready for operation. The Remote requires approximately 5 sec
to power up.
