NMEA DATA COMBINER (MULTIPLEXER) 

KW909-FMKW909 data combiner for the Keep it simplified s-VDR SVDR VDR voyage data recorder

IN, 8 channels NMEA 0183
OUT, combined data.
4800 or 38,400

The KW909 connects to 8 NMEA 0183 talkers and combines their data on to one line. Applications are getting the data from several instruments into ECDIS, radar or data logger, via its one data input port.

The unit does not care what data is put through, it just stores and forwards it on a first in first out basis. The unit may be called a multiplexer or integrator. As such it is ideal for creating a data highway for a ship.

Attention has to be given to possible overload of the output channel, as it impossible to pass more than 480 characters per second through it at the NMEA 0183 4800 rate. Answer, switch the output to 38400. To special order a data filter interface may be what is required.

INPUT:
8 NMEA 0183 ports. 4800 baud.
Accepts $ or ! header. LF terminator is used to detect end of sentence. 
One port can switch to 38400.
OUTPUT:
NMEA 0183, 5v level, 5 mA, RS422, RS232 compatible.
Data on a first-message-in, first-message-out principle.
Data is discarded in event of overload of inputs.
POWER ETC:
9 to 32 v DC at 200 mA.
Black texture coat aluminium diecast box 222 x 146 x 55 mm for indoor bulkhead mounting.
Fitted with compression glands. Single pcb.
Leds on data in and out and bicolour status led indicating output channel loading.
