This is a multipart series of design, prototype and build of a small multiplexing system for UTV's. Initially this will replace lighting and winch relays with solid state control. In this part 3, I go over the base software using OSX with the STM8.

RZR Mini Multiplexing Part 1 – A Smart Solid State Relay for Lightbar, Winch, and anything else on a UTV.

RZR Mini Multiplexing Part 1. This is a multipart series of design, prototype and build of a small multiplexing system for UTV's. Initially this will replace lighting and winch relays with solid state control. The goal is to replace the traditional use of a relay in the rzr for winch and lighting control. Later I will integrate this with canbus work for speed and gear info from the Polaris RZR to turn on reverse lights based on gear selection and turn on rock lights at low speed.

Motorola R2210B/HS Service T/R Part 3.

I purchased a non-working Motorola R2210B/HS service monitor just to take a look and see if it was repairable.   In Part 3, I fix and test all the issues found and end up with a working service monitor.
