Y1157A Cable Kit Assembly
The Y1157A is a 10-pin ribbon connector to 9-pin D-Sub cable kit. The kit
contains materials to build four cables and is used with the following
distribution boards:
• Y1150A
• Y1152A
• Y1154A
The switches used with the Y1150A, Y1152A, and Y1154A which can also use
the Y1157A cable are identified in Table 1-2.
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 1-1. When using the
D-sub connector, always refer to the pin orientation shown in the figure. Do
not use the pin numbers 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 1-2. 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).
