Connecting with NMEA 0183 devices
V3100 supports two NMEA 0183 ports and external silent mode
switch with its 12-pin data cable. The default NMEA 0183 baud rates
are 38400-bps (high speed) and 4800-bps (low speed). The baud
rates can be changed with the provided configuration tool. Typically
the high-speed setting is primarily for chartplotter connection, while
the low-speed setting can be used for NMEA 0183 compatible
instruments.
The NMEA 0183 ports support a multiplexer function. Received
NMEA 0183 data from both ports will be multiplexed and forwarded
to all output ports as well as USB.

Warning: During installation you may have to peel off some
wires to make the appropriate connections. After completing
the installation, please cover all exposed wires with a rubber-
vulcanized tape to prevent the devices from malfunctioning or
short-circuit.
