Instead, the entire computer was documented in a few big books of Boolean algebra equations, liberally annotated, with pinouts. These computers were among the first to have no drawn schematics, primarily because the stack of drawings would have been 20-feet high and impossible to maintain as modifications and improvements were made. Back then I was a mainframe computer technician charged with keeping several new generation room-sized computers functioning-yup, you calculated right, I was 19, it's a long story. And yes, that would have been true.up until about 1970. What, you say? Everyone knows a schematic is the way it's done.

A few hours into the project about half the electronics on the boat were having a sulk and not talking to the other half, and I was becoming increasingly confused and frustrated as I changed wiring and software settings only to fix one thing but break another.Īfter staring into space for a while-really hope my mouth was not hanging open as at my age this is a look to avoid at all costs-I realized that the answer to this was to stop changing wiring and settings and instead plan and document the new network first.Īnd that's what this article is about, an easy way to:

The relatively simple NMEA 2000 network on the McCurdy & Rhodes 56 with the new autopilot and compass added.Īnd, further, when we added the plotter I documented the simple NMEA 2000 network in Martron's excellent N2K Builder.

Particularly since we have always kept our NMEA 0183 network well organized with multi-conductor cables from each unit routed into a central patch panel (see photo at top of article) that Phyllis built, documented and labeled-she turns being organized into an art form. After all, I'm an electronics technician by trade and I have been messing with boat networks for 35 years.

Still, after getting the new kit installed and working, I was confident that getting the networks integrated would be easy and take half an hour or so. The new brain also came with a new digital compass and needed to be controlled by the B&G Plotter we installed a couple of years back in anticipation of just this scenario, all NMEA 2000. Wouldn't you know it, as soon as we put our McCurdy and Rhodes cutter on the market last summer, the Simrad/Robertson autopilot brain that had been reliable for over 20 years and at least 100,000 miles decided to turn its little electronic toes to the air.Īnd, of course, the new B&G brain I selected-mainly because it is a successor to the old one and therefore compatible with the existing bomb-proof drive comprising a Simrad hydraulic pump and massive ram-is all NMEA 2000, while the old brain was a combination of proprietary connections (Simrad Robnet) and NMEA 0183. Multi-conductor cables are run from here to all areas on the boat with navigation and/or communications equipment so changes and additions can easily be made.
