To assemble and wire-up the RJ/45/DB25 adapter:
1. Use the wiring diagram for your configuration (Figure 3-11 for a DMA8Plus or CP750
or Figure 3-12 for a CP650), then insert (snap) the pre-wired contacts into the DB25
(P1) housing, and secure the two pieces.
2. Attach a label (25 inches x 9 inches) in the area shown in the wiring diagram (e.g.,
DB25 to 4xAES input or DB25 to Option I/O input).
3. If a drain wire is provided, attach it to the DSUB housing.
