McCain ATC NEMA Controller – User Manual
Version 1.0
APPENDIX E: CONNECTOR’S DETAILS, OPTIONAL CONNECTOR BOXES
The ATC NEMA controller is a TS2 Type 1 controller that can be converted to a TS2 Type two controller by
adding an optional connector box in order to support the functionality of the A, B, C connectors of the TS1
standard plus the special configuration D connector.
Currently there are two optional boxes, the Standard McCain connector Box and the Traconex compatible box.
The only one difference between them is the special configuration D connector.
Below is listed the pin assignment for each connector.
