34 n.m). Peak the alignment for maximum voltage at the remote antenna. Expected voltage
is more than +1 VDC. The adjustment should be slowly tuned through the peak, and reset at
the absolute maximum before tightening the bolts.
62 Disconnect the hand-held voltmeter and BNC test lead from the RSSI port.
63 Finger-tighten the RSSI port cap to seal the Link CX case.
64 Recheck the Link CX LEDs. See Figure 4-1 and Table 4-1 for the locations and descriptions
of the Link CX LEDs.
• When power is properly applied to the Link CX, the PWR/LCL ALARM LED will be on.
• Because the radio link has been established, the RF LINK LED should be on.
• When the DS-3 equipment is or is not transmitting data to the Link CX, the DATA LED
should be on or off, respectively.
• When the Ethernet equipment is transmitting data to the Link CX, the ENET 1 and/or
ENET 2 LEDs should be on or flashing. When the Ethernet equipment is not transmit-
ting data to the Link CX, the ENET 1 and/or ENET 2 LEDs should be off.
If any of these conditions is not true, troubleshoot the associated equipment and cables.
The Link CX is now mounted and aligned. Continue with Section 4-7 for acceptance tests.
4-6.2 Integral Antenna on a Dual Adjustable Elevation Mount
Perform Step 63 through Step 68 on the local radio. Then, repeat these steps for the remote radio. See
Figure 4-10 for the Dual Pole Mount illustration.
65 Remove the Link CX cap from the BNC connector of the remote radio. Attach the hand-held
voltmeter and BNC test lead to the test point.
66 Fine Azimuth Alignment -- Rotate the Link CX on its mounting bracket until the proper
azimuth alignment is achieved. Torque the four small azimuth locking bolts to 4 to
6 foot-pounds (5.5 to 8 n.m). Peak the alignment for maximum voltage at the remote
antenna. Expected voltage is more than +1 VDC. The adjustment should be slowly tuned
through the peak, and reset at the absolute maximum before tightening the bolts.
67 Fine Elevation Alignment -- Rotate the Link CX mounting bracket until the proper elevation
alignment is achieved. Torque the two large elevation locking bolts to 20 to 25 foot-pounds
(27 to 34 n.m). Peak the alignment for maximum voltage at the remote antenna. Expected
voltage is more than +1 VDC. The adjustment should be slowly tuned through the peak, and
reset at the absolute maximum before tightening the bolts.
Alignment for each antenna should be alternated at least twice before
confirming the final setting.
