6.Connect the 10BaseT connector to the network. The 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 90 meters.

2.5.1 Configuring Parameters

Before aligning the antenna, certain key parameters must be configured to enable connectivity with linked units.

See Unit Configuration Mode on page 209 for more information.

2.5.2 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 DWL-1800 units, have a narrow beamwidth 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 DWL-1800R unit.

To align the antenna:

1. Confirm that the units at both ends of the link are receiving power.
