[. . . ] When choosing a location for the GPS antenna, consider these guidelines: · · · The antenna has an unobstructed view of the sky. The antenna is safe from damage during normal vehicle operation and maintenance. The antenna is not shielded from satellite signals by metal objects or other impenetrable materials. GPS signals can penetrate plastic, glass and tinted glass (except metallized glass), fiberglass, and plexiglass materials as long as the surface is relatively dry. Since GPS satellite signals can penetrate plastic, fiberglass, and glass, the GPS antenna can also be installed on a dashboard under a sloped windshield (if the windshield is not metallized) or under a plastic fender or bumper. These alternative locations are likely to offer less satellite coverage, since the metal components of the vehicle shield the antenna from portions of the sky. For optimum performance, the GPS antenna should be mounted on a metal groundplane of at least 7. 5 cm square (3 in. x 3 in. ). I Caution ­ Do not mount the GPS antenna under a metallized glass windshield, such as those used in some vehicles for window defogging or de-icing systems. However, the GPS antenna can be mounted under a tinted-glass windshield. Disclaimer - The instructions included in this section apply to the GPS antennas sold by Trimble and may not apply to third-party products. There are many other GPS antennas available on the market which may or may not be compatible with the CrossCheck CDPD, including combined GPS/CDPD cellular antenna solutions which have not been tested or certified by Trimble. 20 CrossCheck CDPD Installation Manual Installation 2 Additional guidelines to follow include: · Mount the antenna in a horizontal position facing the sky, as shown in Figure 2. 5. If the antenna must be located in the vicinity of other antennas (radio, cellular phone), locate the GPS antenna at least 46 cm (approximately 18 in. ) away. For permanent installations, choose a location with access both above and below the antenna-mounting surface. This access is required for installing fasteners and for routing the antenna cable. Note ­ The standard length of magnetic-mount and bulkheadmount GPS antenna cables supplied by Trimble is 5 m (approximately 16 ft. ). Longer bulkhead-mount antenna cables can be prepared by the installer using the guidelines presented in Appendix A.

Make sure the wind deflector is not painted with a metallic finish. Note: Must be fiberglass Figure 2. 7 Antenna Mounted under Fiberglass Canopy Note ­ The GPS antenna may be subject to performance degradation when covered by a heavy layer of snow or ice. If these are typical conditions for your application, mount the antenna in an accessible location so snow can be easily removed. The CrossCheck CDPD can receive GPS signals from one of two types of optional Miniature Bulkhead GPS antennas, or a Miniature Magnetic GPS antenna, all available from Trimble. Follow the applicable procedure (below) to mount the GPS antenna. 24 CrossCheck CDPD Installation Manual Installation 2. 7. 1 2 Miniature BulkHead GPS Antenna with Flange (P/N 31192-00) Two cables are available for the Miniature Bulkhead Antenna with Flange: · · A straight TNC-Plug-to-SMA-Plug antenna cable (P/N 36107) A right-angle TNC-Plug-to-straight SMA-Plug antenna cable (P/N 36106) For more information, see Appendix A. Figure 2. 8 shows the Miniature Bulkhead GPS antenna mounting. Mounting Lug Gasket Cable Mounting hardware. Only two of four sets shown for clarity. Figure 2. 8 Miniature Bulkhead GPS antenna with Flange CrossCheck CDPD Installation Manual 25 2 Installation To mount the Miniature Bulkhead GPS antenna with Flange: 1. Drill holes in the mounting surface using the antenna mounting template shown in Figure 2. 9. 19 mm (3/4 in. ) 7. 6 cm (3 in. ) 3. 8 mm (5/32 in. ) Figure 2. 9 Mounting Hole Dimensions 2. Slip the antenna through the larger hole in the center of the hole pattern and rotate the antenna until the four holes in the antenna mounting flange are aligned to the hole circle. [. . . ] When one or more LED indicators are on or blinking, the power is on. CrossCheck CDPD Installation Manual 57 3 3. 2. 2 Operation LED Power-On Sequence When the CrossCheck CDPD's ignition input and power inputs are activated: · · The LEDs blink once. Both turn off for approximately 5 seconds. The GPS LED is on for approximately 2 seconds, then blinks until the first position fix is computed. The CDPD LED blinks until the unit is registered with a CDPD network, at which point the CDPD LED turns on. 3. 2. 3 GPS and CDPD LED States Table 3. 1 identifies the GPS LED states.
