3.2.1.3.4 Counters Tab
Figure 14: Counters Tab (BU/DWL-1800B Units)
Figure 15: Counters Tab (RB/DWL-1800R Units)
Using the Counters windows, you can view a wide range of performance data at
both sides of the link. For RB units, you can monitor the received signal strength
through the RSSI (Received Signal Strength Indication) bar indicator at the bottom
of the window. This RSSI bar can be used to optimize antenna alignment and
improve link quality.

- Point to multipoint 12
- Point to point 12
- Rooftop installation 12
- Antenna polarization 13
- Antenna polarization must be the same at both ends of the link in most applications the preferred orientation is vertical polarization which is best for above ground propagation 13
- Cell size is determined by the maximum possible distance between the dwl 1800b and a dwl 1800r unit for open outdoor areas with an unobstructed line of sight between the bu dwl 1800b and the dwl 1800r units the suggested maximum distance is up to 6 miles 10km where etsi is the regulatory domain and 15 miles 25 km where fcc is the regulatory domain 13
- Cell size link distance 13
- Central offices 13
- Outdoor installations must have a clear line of sight between antennas solid obstacles such as buildings or hills can prevent the establishment of a link while partial obstacles such as trees or traffic can reduce range extended coaxial cables can cause an increase in signal loss and a reduction in range 13
- Precautions 13
- Specific range tables guidelines and information about extended cables can be obtained from your local dealer or the 13
- Using outdoor range tables 13
- Compliance with radio regulations 14
- Installing the outdoor unit 14
- Connect one end of the grounding cable to the ground terminal and connect the other end to a good ground connection 16
- Connecting the ground and antenna cables 16
- Connecting the indoor to outdoor cable 16
- Grooves pointing outwards these grooves are intended to allow fastening of the screws with a screwdriver 16
- Is located on the bottom panel of the outdoor unit 16
- Note when inserting the open ended screws make sure to insert them with the 16
- Remove the two screws holding the waterproof seal to the outdoor unit and remove the waterproof seal 2 unscrew the top nut from the waterproof seal 16
- The ground terminal marked 16
- Installing the indoor unit 17
- After connecting the outdoor unit to the indoor unit using the indoor to outdoor cable connect the power cord to the unit s ac socket located on the bottom panel shown in figure 7 connect the other end of the power cord to the ac mains after verifying that the unit is rated for the voltage in the country of use the ac rating is indicated on the bottom panel of the indoor unit 18
- Antenna alignment 19
- 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 19
