After quite a bit of searching I've been unable to locate anything they're currently selling that is configurable over serial. They do make a 4 channel controller that can be configured over CAN but it's awfully pricey.
Thinking I'm going to buy one of these gauge setups - they appear to be quite a bit cheaper for the same functionality as the "inline" setups. I would assume this is because the electronics for the gauges don't need to be weather resistant.
