instantaneous reading as you move the antenna. In Normal mode, the RSSI reading has a delay, so you
must stop moving the antenna and wait before taking your reading. The RSSI port is a female BNC
connector on the bridge housing (see Figure 5).
The RSSI voltage increases linearly with signal level as shown in Table 5.
Note A larger RSSI voltage reading indicates a stronger signal.
The voltage varies from 0 to 2.7 volts for signals between –90 and –20 dBm, respectively. The accuracy
over temp
erature and component variations is ± 4 dB. To obtain RSSI readings, you can use any
convenient voltmeter connected to the RSSI port using a cable with a male BNC connector.
Grounding the Bridge
The bridge must be grounded before you connect power. Your grounding installation must comply
with national and local electrical codes. Follow these steps to ground the bridge to a suitable building
ground.
Step 1 Find a suitable building grounding point as close to the bridge as possible.
Step 2 Conn
ect a user-supplied ground wire to the building grounding point. The wire should be a
minimum of #14AWG assuming a circuit length of 25 ft (30.5 cm). Consult your local
electrical codes for additional information.
Step 3 Route
the ground wire to the bridge.
