Miniplex 41BT
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 can be used in the same way
as the Bluetooth interface. Data from the instruments is available on both
interfaces simultaneously. Data from connected computers is received on
both interfaces, combined and sent to the NMEA Output.
This is very useful when a fixed computer is permanently connected to the
RS-232 port, while a PDA with a Bluetooth interface is used as a portable
system or a repeater. When the multiplexer is set to Hub mode, it will
even pass information from the computer to the PDA and vice versa. |

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
ouput. |
| 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.
