Y1158A Cable Kit Assembly
The Y1158A is a 10-pin to 10-pin and 14-pin to 10-pin ribbon connector cable
kit. The Y1158A kit contains materials to build two cables of either type or one
of each and is used with the following distribution boards:
•
Y1153A (10-pin to 10-pin cable)
•
Y1154A (14-pin to 10-pin cable)
The switches used with the Y1153A and Y1154A which can also use the
Y1158A 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 1-3.
Figure 1-3. Distribution Board Socket and Y1158A Cable Connector Orientation.
The steps for building the cables are as follows:
10-pin to 10-pin Cable
1. Cut the ribbon cable slightly longer than the desired length to allow for
strain relief.
2. Position the ribbon cable connectors as shown in Figure 1-4. Route the cable
through
the connectors, noting the location of pin 1 on the cable. By
convention, pin 1 is indicated in red (the dark line in the drawing).
