6.
Connect the 10BaseT ETHERNET connector (marked
cable connection should be straight Ethernet if connecting the indoor unit to a
Hub and a crossed cable if connecting it directly to a PC Network Interface
Card (NIC).
NOTE:
The length of the Ethernet cable connecting the indoor unit to the user's equipment, together with the
length of the indoor-to-outdoor cable, should not exceed 100 meters.

Configuring Parameters

Before aligning the antenna, certain key parameters must be configured to enable
connectivity with linked units.
See Unit Configuration Mode on page 3-3 for more information.

Antenna Alignment

Usually, low gain antennas do not require alignment due to their very wide
radiation pattern. High gain antennas, including the integral antenna of DS.11
units, have a narrow beam-width necessitating an alignment procedure in order to
optimize the link.
Check the antenna alignment by using the RSSI bar on the bottom panel of the
RB-DS.11 unit.
To align the antenna:
1.
Confirm that the units at both ends of the link are receiving power.
2.
Synchronize the units by aligning the antennas at the base and remote sites
until maximum signal quality is obtained. Check the signal quality Received
Signal Strength Indication (RSSI) bar on the bottom panel of the RB-DS.11.
The first LED lights red to indicate that the unit is working. The remaining
nine LEDs light green to indicate the signal strength. The stronger the signal
the more LEDs are lit. Rotate the antenna slowly to the left or right using
small increments until you reach the point of maximum RSSI reading. Make
sure that at all times the front of the antenna faces the general direction of the
BU-DS.11.
