2.5.5 Modifying an IOBUS Cable
A standard IOBUS extension cable, shown in Figure 2-10, must be modified when the IOBUS must
transition between a user supplied terminal block and the IOBUS IN or IOBUS OUT connection point on a
rack’s backplane that requires a factory-prepared cable end with a molded connector.
To modify an IOBUS A or B Cable:
1. Cut the Cable in half.
2. Prepare the cable ends as shown in Figure 2-20.
