Cable Assembly Connectors
The cable assembly listed under Optional Equipment in Chapter 1 is an assembly of two 50-pin
cables and three connectors. Both cables are joined to a single connector on one end and to
individual connectors on the free ends. The connector that joins the two cables is a 100-pin
connector that plugs into the I/O connector of the PC-DIO-96. The other two connectors are
50-pin connectors, one of which is connected to pins 1 through 50 of the PC-DIO-96 I/O
connector, and the other of which is connected to pins 51 through 100 of the PC-DIO-96 I/O
connector. The cable with the label on it is connected to pins 1 through 50. Figures 2-5 and 2-6
show the pin assignments for the 50-pin connectors on the cable assembly.
