@Jim Van Every posted:I'm using a mth 4000 transformer and a tiu Rev Il. I want to use my cab-1 controller and box. I just got the revised cable 1050 (truly a crappy fit) ,and ran a ground to the track. No response, no green light. Help! I'm confused. Thanks for your time
Problems with the above.
#1 Green light is the power status light on the TMCC command base- Implies your power adapter is not plugged in or working.
#2 "I just got the revised cable 1050 " , problem is, typos aside, should be an MTH 50-1032 or the older cable version was 50-1007. All this cable does is connect the command base serial port to the TIU serial port so that the TIU can send TMCC formatted commands to the base. It's a one way communications TIU to base.
I would go back to basics first. Follow the basic TMCC and DCS at the same time diagram, then once you get that working, THEN worry about the 50-1032 serial data cable.
@CAPPilot did a great job with this diagrams https://ogrforum.com/topic/151...3#151069472633553813
Edit, realized that showed a TIU in passive mode- too complicated.
This edit I did based largely on previous drawings above and modified.
