3.1 OVERVIEW

It is convenient to set up a tabletop network that can be used to verify
the basic operation of the transceivers and give you a chance to experi-
ment with network designs, configurations or network equipment in a
convenient location. This test can be performed with any number of
radios.
NOTE: It is important to use a "Network Name" that is different from
any currently in use in your area during the testing period. This
will eliminate unnecessary disruption of traffic on the existing
network while you become familiar with the transceiver or
evaluate variations of unit operating parameters.
To simulate data traffic over the radio network, connect a PC or LAN to
the Ethernet port of the Access Point and PING each transceiver several
times.
3.2 STEP 1—INSTALL THE ANTENNA
CABLING
Figure 3-1 is a drawing of the tabletop arrangement. Connect the
antenna ports of each transceiver as shown. This will provide stable
radio communications between each unit while preventing interference
to nearby electronic equipment from a large number of co-located units.

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 –50 dBm be applied to any transceiver in
the test setup. An RF power output level of +20 dBm is recom-
mended. (See "Radio Configuration Menu" on Page
