Title: WMS 550 Touchscreen Post by: idylewild1 on November 20, 2013, 11:57:45 PM I'm upgrading a WMS 550 to an LCD monitor. Need help wiring the touchscreen. The 550 has five wires 3 yellow and 2 black. Need info on how to wire to a 3m controller. Thanks for any help.

For reference the yellow wire next to the black in the molex is yellow/brown and the other one is yellow/black. The DB9 should be a standard serial port (ground, TX, and RX) if your 3M controller does not already have the db9 on it.
