Appendix B: Y1157A Cable Assembly Instructions
The Y1157A is a 10- pin ribbon connector to 9- pin D- Sub cable kit which contains materials to build four cables.
The key to building the cables correctly is to understand the orientation of the socket pins on the distribution boards and the pin number orientation of the cable connectors. This orientation is shown in Figure B- 1. When using the D- sub connector, always refer to the pin orientation shown in Figure B- 1. Do not use the pin numbers printed on the part.

The steps for building the cables are as follows:
1Cut the ribbon cable slightly longer than the desired length.
2Position the D- Sub connector and the ribbon cable connector as shown in Figure B- 2. Route the cable through the connectors, noting the location of cable pin 1. By convention, pin 1 is indicated in red (the dark line in the drawing).
