Here is the deal. The 4 terminal TX wiring is pretty obvious. (I have a unit with the 4 terminal to compare with)
The 6 terminal I have ohmed out and it is not obvious! Pins 1 to 3 and 2 to 4 (.5 Ohms) appear to be the 120VAC windings and hooking them in parallel should do the trick. As wired for 240 VAC 1 to 3 and 2 to 4 are in series which makes sense. However when the 4 terminal is wired for 240VAC a wire comes off the input center tap to provide 120VAC to some circuits in the unit. The 6 terminal when wired for 240VAC has an extra wire connected to pin 8. Pin 8 to 1 and pin 9 to 2 show .2 Ohms so they look like maybe taps for a different input voltage slightly different from 120VAC. The problem there is that the wire to pin 8 which would logically go to the center tap as above goes to this pin 8 tap which makes no sense! Of course it could have been miswired when I got it! All the manuals I can find by Goggling show the 4 pin TX! Was hoping someone might have a unit with the 6 pin TX wired for 120VAC so they could advise me!
