19.11 INSTALLING A BH TIMING SLAVE
To install the Canopy BHS, perform the following steps:
Procedure 35: Installing the BHS
1. If this is a 20-Mbps BH, set the Modulation Scheme parameter in the
Configuration web page of the BHM to 10 Mbps (for easier course aiming).
2. Remove power from the BHS.
3. Choose the best mounting location for your particular application.
4. Optionally, attach the BHS to the arm of the Canopy Passive Reflector dish
assembly as shown in Figure 111.
RECOMMENDATION:
The arm is molded to receive and properly aim the module relative to the
aim of the dish. Stainless steel hose clamps should be used for the
attachment.
5. Align the BHS as follows:
a. Move the module to where the link will be unobstructed by the radio horizon
and no objects penetrate the Fresnel zone. (The Canopy System Calculator
page AntennaElevationCalcPage.xls
automatically calculates the minimum
antenna elevation that is required to extend the radio horizon to the other end
of the link. The Canopy System Calculator page FresnelZoneCalcPage.xls
automatically calculates the Fresnel zone clearance that is required between
the visual line of sight and the top of a high-elevation object.)
b. Use a local map, compass, and/or GPS device as needed to determine the
direction to the BHS.
c. Apply the appropriate degree of downward or upward tilt. (The Canopy
System Calculator page DowntiltCalcPage.xls
automatically calculates the
angle of antenna downward tilt that is required.)
6. Using stainless steel hose clamps or equivalent fasteners, lock the BHS into
position.
7. Remove the base cover of the BHS. (See Figure 47 on Page 132.)
8. Connect the DC power converter to the BHM and then to an AC power source.
RESULT: When power is applied to a Canopy module or the unit is reset on the
web-based interface, the module requires approximately 25 seconds to boot.
During this interval, self-tests and other diagnostics are being performed.
9. Connect the module to an Ethernet port on a computing device.
