NMEA IN and NMEA OUT

After a day of plumbing yesterday, we are on to a day of wiring today.  We started by running new wire between the electrical panel and the new tiller pilot at the stern of the C'est la Vie. Then on to disconnecting the GPS and pulling those wires into the electrical panel.  The inside of the electrical panel is pictured below.

With all the wiring lead to the panel, we then installed the new network block that I discussed in the May 29th post.  The network block is the green and grey rectangle in the upper right the electrical panel pictured above.

When we correctly connect the GPS, autopilot, VHFs together in the block they should all communicate using the language known as NMEA 0183.  The conversation is a bit one sided as NMEA 0183 will allow the GPS to talk while the other devices listen.  Sound simple enough?  Well figuring out which wires to link together from each device and tracking down all the various wires is requiring some additional research...

GASP!... that is right we are actually reading the manuals.  I sure hope this works...
