NMEA 2000 to NMEA 0183 Gateway - NGW-1
Page 5© 2013 Active Research Limited
Connecting to the NMEA 2000 Network
Actisense supplies a pre-tted four-core screened cable for the NMEA 2000 connection, tted with a male micro-t
connector. Simply connect the cable to the network backbone using a T-peice connector.
NMEA 2000 Networks
NMEA 2000 devices will only communication with each
other when connected to a powered and correctly
terminated NMEA 2000 network. It is not enough to simply
connect two NMEA 2000 devices directly together.
All networks need to be powered and terminated correctly
to allow data to be transmitted on the network. T-Peices
are needed to connect each device to the network.
Additional cable lengths can be used between any of the
connectors to extend the length of the network.
NMEA 2000 Minimum Network Requirements
All NMEA 2000 networks require 12 VDC to be supplied.
• 1 x Power-T
• 2 x Terminating Resistors
• 2 x T-Peices (one per connected device)
All the required network parts are supplied by Actisense
www.actisense.com/A2K.
Note: Refer to “Status LEDs” on page 10 for LED
behaviour.
Connecting to a SeatalkNG Network
The NGW-1-STNG is a standard NGW-1-ISO unit with the addition of a Seatalk
NG
to NMEA 2000 adapter cable supplied
in the box. Connect the adapter between the NMEA 2000 cable of the NGW-1 and the Seatalk
NG
backbone. Seatalk
NG
,
like NMEA 2000, requires a fully functional network to connect devices together. It is not possible to connect the NGW-1
directly to a Seatalk
NG
device without a powered and terminated network being present. Refer to your Raymarine
®
product manual for instructions on creating your Seatalk
NG
network.
USB Driver Installation
Windows 7 will automatically install the drivers from
Windows Update (an active Internet connection is
required). If the PC is not connected to the Internet, the
‘Update Driver Software’ option in Device Manager will
need to be used to install the USB drivers manually.
Windows versions that use the ‘Found New Hardware
Wizard’ should be directed to automatically search for the
best driver. Include ‘Search Windows Update’ or ensure
the Actisense CD is inserted.
For other operating systems and step-by-step guides refer
to the ‘USB Install Manual’ at
www.actisense.com/NGW-1/Downloads.php.
Windows Port Number Conguration
The port number for the NGW-1 can be found in Windows
‘Control Panel->System->Device Manager’ under ‘Ports
(COM & LPT)’. Find the NGW-1 in the list for the USB
variant. When using a USB to serial converter cable you
will see the name of the converter cable with no reference
to the NGW-1. If you have connected to an RS232 port on
the PC this will be listed as a ‘Communications Port’, again
with no reference to the NGW-1.
To change this number, double click the NGW-1 and select
the ‘Port Settings’ tab. Click the ‘Advanced’ button and
change the port number to the one required.
Connecting to a USB Port
Simply connect the USB cable on the NGW-1 to the PC port and install the drivers. A USB to serial converter cable can
be used to connect the non USB variants to a PC USB port. For wiring the converter cable refer to “Connecting to an
RS232 (PC) Port” on page 7.
Note: Refer to “Status LEDs” on page 10 for LED behaviour.
