Thanks for the feedback folks. I see the C130J model has a panel on the center console with the 4 trim indicators in an edge lit panel, rather than 4 2" gauges like the older models. Still a little confused about the 3 signals from the transmitter to the indicator. If it was a synchro, those might be s1 s2 s3 400hz ac. If it was just a meter movement, I could see gnd and 0-5V or something. We were trying to respond to a request for quote for the new style 4 indicators in a panel (spare parts for foreign sales or ??), and thats why I was wondering what the signal from the position transmitter was.
