3 While viewing the multimeter, sweep the IFU vertically by pointing the
IFU all the way up and then down. The measured voltage of the
multimeter displays a succession of peak signals as the IFU moves.
Specifically, the signal displays a “small” peak, a relatively higher peak,
and then redisplays the “small” peak. When the higher peak occurs, note
the approximate position of the IFU and the corresponding voltage value.
The peak voltage should be approximately 3 Vdc.
4 Move the IFU to the higher peak position as indicated by the multimeter
display.
5 Tighten the four vertical screws on the IFU mounting bracket.
6 Loosen the horizontal alignment nut on the IFU mounting bracket.
7 Sweep the IFU from the far left to the far right. The measured voltage of
the multimeter displays a succession of peak signals as the IFU moves.
When the higher peak occurs, note the approximate position of the
IFUand the corresponding voltage value.
8 Move the IFU to the higher peak position as indicated by the multimeter
display.
9 Tighten the horizontal alignment nut on the IFU mounting bracket.
10 Access the IFU Link Manager application and enable Adaptive Transmit
Power Control for both the near-end and the far-end IFUs (refer to IFU
Link Manager online help).
11 Record the minimum, maximum, and actual RSSI levels set for the IFU in
Table A-4 on page A-2 and Table A-6 on page A-3.
12 Turn off the laptop computers, disconnect the test cables, and replace the
protective caps on the IFU test connectors.
13 Secure all IFU cabling with UV-rated tie-wraps. Continue to tie wrap the
cables every 18 inches until they enter the building.
NOTE: Refer to your project manager or liaison for commissioning
procedures applicable to your network.
