Appendix B: Y1157A Cable Assembly Instructions

U2121A-101 Operating Guide
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
printed on the part.

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