7.1 Aligning the Antenna Using a DVM
1. Connect the technician cable to the Monitor port on the bottom panel of the
Outdoor unit.
2. Connect a DVM (Digital Voltmeter) to the two wires in the technician cable.
3. Move the antenna left and/or right until you reach the point of maximum RSSI
reading. RSSI readout range is 1.50 to 3.30 volts (the higher the better). Make
sure that all the time, the front of the antenna faces the general direction of the
Base Station so as not to use the back lobe rather than the front lobe of the
antenna for tuning.
4. For proper operation the RSSI reading should be at least 2 volts. If maximal
reading is lower try to improve it through placing the antenna higher or in a
different location.
Note: The DVM reading might be inaccurate due to possible reception of
energy from other devices transmitting energy in the 2.4GHz ISM band.
When in doubt, verify performance using the Print-Per-Hop Statistics
that is based on measurement of the desired signal only.
7.2 Aligning the Antenna Using the Site Survey Menu
1. To use the Site Survey menu configure the ESSID parameter (refer to
Section 8.4).
2. Connect the terminal to the Outdoor unit using the technician cable.
3. From the main menu type 3 to access the Site Survey menu. Type 3 to access
the Print Per-Hop Statistics selection screen. Type 1 to display RSSI readouts
per frequency. In order to update the screen press Enter twice.
