Appendix C
Network Connector Pin Assignments
This appendix assumes the network cable system has been installed using the
appropriate A-B Data Highway Plus instruction manual.
The faceplate of the Data Highway Plus Interface module contains a Phoenix
Combicon connector for connection to the Data Highway Plus network. Each
station is connected to the Data Highway Plus network trunk-line using a drop-line
constructed of Belden 9463 twin-axial cable (or equivalent).
The connector has 6 pins, which are numbered from the bottom. The bottom bin is
pin 1; the top pin is pin 6. Pin 1 is internally connected to 4, pin 2 to pin 5, and pin
3 to pin 6. Any connections to pins 1, 2 or 3 could also be made to 4, 5 or 6
respectively.
The CLEAR wire of the twin-axial cable should be connected to Pin 1 or 4 (bottom
pin or pin 4) of the Phoenix connector, the DRAIN (bare) wire to Pin 2 or 5 and the
BLUE wire to Pin 3 or 6. The color wire that is at the top on the three pin
connector on the A-B device is the color you connect to pin 1 on the connector on
the Data Highway Plus Interface module faceplate. See the figure below.
