• Replace the base cover on all of the backhaul modules.
Alignment
• If the backhaul modules are not utilizing passive reflectors, then visually align the units.
• If the backhaul modules are utilizing passive reflectors then visually align if possible or utilize
compass headings and initiate step 1 in the following process:
1. Lock down timing master module
2. On the timing slave module, utilize RSSI only mode of alignment web page:
• Choose the frequency to monitor from the pick list (this would be the same
frequency that the backhaul timing master module is transmitting on)
• Click the radio button to highlight “Enable” on RSSI Only mode
• Click “Enable Aiming Mode”
The module will now report back the level of RF energy present at that specific
frequency. To refresh the screen, click the
Enable Aiming Mode button as appropriate
or configure the web page auto-refresh option. The minimum RSSI level for a link is
greater than 700.
3. When RSSI value is above minimum, disable RSSI Only mode and monitor the Status
web page:
a. Watch for “Syncing”, then “Registering”, then “Registered”. When the unit is
registered, move on to Step 4.
4. While monitoring RSSI and Jitter, at the incrementally move the timing slave module in
the vertical plane. Observe where the values are at their best and lock down the unit.
Now, incrementally move the timing slave module in the horizontal plane. Observe
where the values are at their best and lock down the unit. Alignment is complete when
reported values are at their best and the unit is registered.
5. If necessary, incrementally move the timing master module a couple (2-3) degrees and
go back to Step 1.
