Nmea 2000 And Simnet Devices; Iec61162-1/2 (Nmea 0183) Devices - Simrad GN70 Operator And Installation Manual

NMEA 2000 and SimNet devices

NMEA 2000 devices can be connected to the CAN bus providing they are NMEA 2000
certified, meet the CE, FCC regulations and do not exceed the load specification.
NMEA 2000 devices and SimNet devices with Micro-C connectors connects directly to the
CAN bus backbone using drop cables and Micro-C T-joiners.
¼ Note:
It is recommended to use a gateway when connecting non-Simrad units to the CAN
bus backbone.
Devices with SimNet connectors only must be connected using a SimNet to Micro-C adapter
cable.

IEC61162-1/2 (NMEA 0183) Devices

Connects to:
The MX610JB board includes 4 NMEA Port terminals, while the MX612JB unit has 12 NMEA
port terminals.
¼ Note:
Ports 3, 7 and 11 are high speed ports.

(NMEA0183)
DEVICES
RX1
The green LED at each NMEA port terminal will flash when serial data is received.
The MX61xJB board uses the serial RS422 (IEC 61162-1/2) standard and can be configured
in the GN70/MX61x display for different baud rates, up to 38,400 baud (default baud rate is
4800). Sentence output by the GN70/MX61x can be individually turned on or off. The default
NMEA sentence setting is off.
¼ Note:
Limit the number of NMEA sentences turned on to eight (8) per port. Although the
junction box allows you to turn on more than eight and will output all messages you turn on,
the MX61x JB memory can only retain up to 8 sentences per port when power is turned off.
