19.8 VERIFYING AN AP-SM LINK
To verify the AP-SM link after the SM has been installed, perform the following steps.
Procedure 33: Verifying system performance
1. Access the web-based interface for the AP (by opening http://<ip-address
>,
where <ip-address> is the address of the individual module).
2. In the menu on the left-hand side of the web page, click on GPS Status.
3. Verify in the Satellites Tracked field that the AP is seeing and tracking satellites.
(To generate the timing pulse, the module must track at least 4 satellites.)
4. Verify that the Antenna Status field displays the value OK.
5. Access the Status Page of the SM.
6. Verify that the SM is still registered to the AP.
7. Access the Configuration page of the SM.
8. Note the frequency that is selected in the Custom RF Frequency Scan
Selection List field.
9. Access the Configuration page of the AP.
10. Verify that the frequency that is selected in the RF Frequency Carrier field is the
same as noted above.
11. Access the AP Eval Data page of the SM.
12. Verify that the AP is shown in the Sector ID field.

19.9 INSTALLING A REFLECTOR DISH
The internal patch antenna of the module illuminates the Canopy Passive Reflector Dish
from an offset position. The module support tube provides the proper angle for this offset.
19.9.1 Both Modules Mounted at Same Elevation
For cases where you are mounting the other module in the link is mounted at the same
elevation, fasten the mounting hardware leg of the support tube vertical for each module.
When the hardware leg is in this position
◦ the reflector dish has an obvious downward tilt.
◦ the module leg of the support tube is not vertical.
For a mount to a non-vertical structure such as a tapered tower, use a plumb line to
ensure that the hardware leg is vertical when fastened. Proper dish, tube, and module
positions for a link in this case are illustrated in Figure 108.
