Which Multiplexer ?

Over a year ago I searched high and low for the “perfect” multiplexer and readers of this blog will know that I selected the Brookhouse from New Zealand in the end {more of that in this post from last year}.

Configuration for nearly all these units is by using Hyperterminal or similar software – so you had better find out how to do that!. {see my posting on this program here}

This is a new unit from on sale at Marine Electronic Service Ltd for £194 inc VAT.

Eissing SB2006– 1x input NMEA0183 / RS-422 isolated

– 3x input NMEA0183 / RS-422 isolated

– 1x output NMEA0183 / RS-422 isolated

– 1x COM port (RS-422 level)
– power supply for external equipment

You should note that RS422 is not RS232 or RS232C which is the “older” and slower PC comms port standard – but nevertheless make sure that the laptop you want to connect to supports RS422 as its serial connection…{see my post here on the subject}.

I cant vouch for its operation since I am very happy with my Brookhouse. But you may want to compare the two if you are about to take the step of trying to integrate AIS and other slower NMEA instruments into your chart plotter or laptop. {See my posting here on the Brookhouse}
