Figure 2-3 DGPS MAX Interface
Refer to Appendix B for further interface information when operating in
the DGPS MAX with various correction sources.
For successful communications, the baud rate of the DGPS MAX serial
ports must be set to match that of the devices to which they are
connected. Refer to Section 4.6.7.1 and Section 4.7.2 for instructions
related to setting the DGPS MAX baud rates.
2.4 Installing the CDA-2MAX Antenna
The location chosen for installation of the CDA-2MAX antenna will
influence the overall performance of the DGPS MAX receiver. When
installing the antenna:
n
Choose a location with a clear, unobstructed view of the sky. This is
important for GPS, WAAS, and OmniSTAR signal reception.
n
Choose a location that is at least three feet away from all forms of
transmitting antennas, communications, and electronic equipment. This will
reduce the amount of noise present at the antenna, improving beacon
receiver performance.
n
The position calculated by the DGPS MAX is measured to the center of the
CDA-2MAX antenna. Install the antenna in the best location for your
application, such as the center line of your vehicle or vessel.
