3.5. CONNECTING THE DRX
This section describes the installation requirements for cables from and to the DRX.
Access to, and connection of all cables should be performed by a qualified installer.
3.5.1. Power Supply
The DRX should use a clean power supply. For best performance use a DC battery supply
or as a secondary alternative it is recommended to use a low noise converter.
CAUTION: A noisy power supply will have direct impact on system
performance.
3.5.2. Connectors and Components
This section identifies the various connectors exposed on the DRX.

CAUTION: All serial cables from sensors on RS-232, RS-422 or NMEA 0183
should be direct with no splitters or interface boxes, unless supplied by
WASSP. Failure to do this will result in compromised mapping performance
due to potential timing issues.
