The MiniPlex-41BT is the first Bluetooth enabled NMEA multiplexer, offering 4 galvanically isolated NMEA inputs, 2 NMEA outputs, a Bluetooth and an RS-232 interface.
The
MiniPlex-41BT communicates with a computer
or a PDA through its' Bluetooth interface
for computerized navigation. No cables need
to be attached. Just placing your laptop at
the chart table, or just being on board for
that matter, is enough to communicate with
your navigation system.
Both NMEA outputs (talker ports) allow
distribution of the NMEA data to up to eight
instruments.

The RS-232 port normally only outputs the received NMEA data from the multiplexer. It can be switched to bi-directional mode, in which case the RS-232 port becomes the 'master' port to connect to a computer. The Bluetooth interface will then only send NMEA data, not receive it. This is a useful configuration when a fixed computer is permanently connected, while a PDA with a Bluetooth interface is used as a slave system or a repeater. |
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 datagrams on a RayMarine®
network into NMEA sentences.
