Visor Pinout

The Gooseman asks: “Do you have a pinout/circuit diagram for making a cable to go from Visor toRS232? I’m thinking of a “straight” serial cable with adaptors for RJ-45, crossover, gender-bending etc….”

What I’ve found so far: Acroname Inc. PPRK Visor Support says that you’ll have to add a chip.

Here’s another page with pinouts, too.
