GPS RECEIVER GP-320B
SAFETY INSTRUCTIONS CAUTION NOTICE Confirm that the power supply voltage is compatible with the voltage rating of the equipment. No one navigation device should ever be solely relied upon for the navigation of a vessel. Connection to the wrong power supply can cause fire or damage the equipment. Always confirm position against all available aids to navigation, for safety of vessel and crew.

SYSTEM OVERVIEW The GP-320B is a GPS receiver with WAAS (Wide Area Augmentation System) capability. WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based Augmentation System) navigation system. An SBAS provider furnishes GPS signal corrections to SBAS users, for even better position accuracy, typically better than three meters.

1. MOUNTING Mounting considerations Follow the guidelines below to choose a suitable mounting location for the antenna unit. • The antenna may be mounted three ways: screwed into a pipe (local supply), fixed to a post with the optional mast mounting kit, or screwed into an optional mounting base. For fixing by the post or pipe, it is recommended to use stays to prevent damage to the GPS receiver. • Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS signal.
2. WIRING This unit outputs position and speed to external equipment. NavNet equipment, Multi Display RD-30 and Echo Sounder LS-6100 can be connected directly. For connection to other equipment, use a junction box (local supply) which has seven terminals. The antenna cable is 10 meters long. If the distance between the antenna unit and the display monitor is more than 10 meters, use the optional cable assy. (10 m). Up to four extension cables can be connected serially.
Connecting to Multi Display RD-30 WAAS is not operative in this installation.
Connecting to other equipment Remove the connector from the antenna cable and attach crimp-on lugs or similar terminals to the cable’s cores. Connect the cores to the junction box as below. Antenna Cable 10 m *: RS-422 signal can be received by using current loop.

4. TROUBLESHOOTING, BATTERY Troubleshooting If the message “No position data” appears on the display of NavNet equipment, there may be a problem with the GPS receiver. Turn off the power and then check the following points: 1) Check for objects around the antenna which may interfere with reception. 2) Check that the antenna cable is firmly fastened. 3) If extension cable(s) are used, check for water leakage at junction point(s). 4) Check the antenna cable for damage. 5) Check the antenna for damage.
