The NGW-1 range allows NMEA 0183 electronic equipment to be connected to a vessel’s NMEA 2000 network.
NMEA 2000 to NMEA 0183 Gateway - NGW-1 Connecting to the NMEA 2000 Network Actisense supplies a pre-fitted four-core screened cable for the NMEA 2000 connection, fitted with a male micro-fit connector. Simply connect the cable to the network backbone using a T-peice connector. NMEA 2000 Networks NMEA 2000 Minimum Network Requirements NMEA 2000 devices will only communication with each other when connected to a powered and correctly terminated NMEA 2000 network.
Connecting a Standard NMEA 0183 Device Actisense supplies a pre-fitted four-core screened cable for connecting devices that comply to the NMEA 0183 specification. Actisense ISO-Drive output circuitry and OPTO input circuitry allows many different types of device to be connected without the need for configuration. Voltage levels are managed automatically as well as accepting both differential and ground referenced connections safely.
NMEA 2000 to NMEA 0183 Gateway - NGW-1 Connecting to an RS232 (PC) Port The NGW-1 can be connected to a PC communications (RS232) port using the supplied cable and a connector with the following specification: 1. A minimum of 3-cores are required in a shielded cable. Higher quality cable will naturally yield higher performance/ higher Signal-to-Noise Ratio (SNR). Most typical cables have two twisted pairs inside. In this case, use one pair for the TX line and one for the RX line.
Connecting a Custom Cable It is possible to replace the supplied cables with custom cables for different applications. The cables are connected inside the case using screw terminals so that it is easy to swap out the existing cable for one more suited to the installation requirements. A spare cable gland is supplied for strain relief and splash proofing. Opening the NGW-1 Case To open a NGW-1 case, remove the two screws in the base of the unit, then carefully lift off the top of the case.
NMEA 2000 to NMEA 0183 Gateway - NGW-1 Configuring the NGW-1 There are currently only a few configuration options available with the NGW-1. All of which are provided in the NMEA Reader software package www.actisense.com/NGW-1/Downloads.php. The configuration options in NMEA Reader are explained in this manual, for more in depth instructions for using the program download the Reader Manual on the link above.
Troubleshooting Guide This guide will concentrate on all relevant troubleshooting issues, that may arise on your NGW-1. Therefore, the cables between the NGW-1 hardware and any other devices should be checked as a matter of course, before continuing with this guide. Status LEDs The NGW-1 hardware has two bright LEDs that can be seen through the case to indicate when data is received from either the NMEA 0183 device or an NMEA 2000 network connection.
