16-18mA at 24 volts. A diagnostic LED indicates the operation mode of the NDC-3, if any faults have been detected, or the peak load currently on any one of the NMEA inputs. Very tough Polycarbonate case is certified to IP66 (classified as “totally protected against dust and protection... -
Page 6: Connecting Devices Together
Actisense™ Connecting devices together The basics NMEA data is transmitted from an information source such as GPS, depth sounder, gyro compass etc. These data sending devices are called “Talkers”. Equipment receiving this information such as a chart- plotter, radar or NMEA display is called a “Listener”. Unfortunately, only one Talker can be connected on to a single NMEA 0183 system at any one time. -
Page 7: Connections
Connections The NMEA Data Combiner (NDC-3) has screw-terminal “Phoenix” type external connections for: - 1. Four NMEA 0183 inputs. All NMEA 0183 inputs are of the differential opto- isolated type and use the unique Actisense™ low current drain circuitry (2mA @ 2.0v) to conform in full with the NMEA 0183 marine electronic device network communication standard, and are flexible enough... -
Page 8: Connecting To Nmea Devices
NMEA 0183 device output specifications. Please determine (from device manufacturer’s information) if the device(s) required to be connected to the Actisense™ NDC-3 conforms in full to the NMEA 0183 network communication standard. If it does not, the flexible Actisense™ NDC-3 inputs should still be capable of interfacing with the device, though this is not guaranteed. -

3. The TX of the NDC-3 should be connected to the RX of the computer (standard D-type, pin 2) and the NDC-3 RX should be connected to the TX of the computer (pin 3). -
Page 10: Troubleshooting Guide
Troubleshooting guide This guide will concentrate on all relevant troubleshooting issues above simple cable connection faults. Therefore, the cables between the NDC-3 hardware and any other devices should be checked as a matter of course, before continuing with this guide. -
