The MiniPlex-41 is
our basic model
NMEA multiplexer, offering 4
galvanically isolated NMEA inputs, 2 NMEA
outputs and one RS-232 interface.
The MiniPlex-41 can be connected to a
computer through the RS-232 interface for
computerized navigation. Stand-alone
operation is also possible, in which case
the RS-232 interface is only used to
configure the MiniPlex-41. This
configuration is stored permanently.
The two NMEA outputs (talker ports)
allow distribution of the NMEA data to up
to eight instruments.
|
|
The MiniPlex-41 is completely
transparent to NMEA data. Incoming data is
simply stored and forwarded as complete
NMEA sentences to the connected
instruments and/or PC. |
Operating modes
The MiniPlex-41 has three
modes of operation, which affect the routing
of NMEA data:
|
| Server: |
Data received on the
NMEA inputs is sent to the computer.
Data received from the computer is sent
to an NMEA output. |
| Hub: |
All received data (on
the NMEA inputs and from the
computer) is sent to an NMEA output.
|
| Auto: |
Automatic selection
between Server and Hub
mode. This is a useful feature for
people who have a GPS and an autopilot
connected to the multiplexer, and
sometimes wish to sail without taking
their laptop on board. When the laptop
is not connected, the multiplexer is in
Hub mode and crosstrack- and
waypoint information from the GPS is
directly sent to the autopilot. When the
laptop is connected and sending data,
the multiplexer automatically switches
to Server mode and the autopilot
will receive crosstrack- and waypoint
data from the laptop instead.
This mode also serves as an emergency
backup: when the laptop or computer
crashes, the multiplexer will fall back
to Hub mode after a timeout of 10
seconds. |

Seatalk®
Conversion
When the
SeaTalk -> NMEA option is selected,
NMEA In 4 becomes a SeaTalk®
compatible input, offering conversion of
the most common SeaTalk data on a
Raymarine® network into NMEA
sentences.
