RJ-21 Cable Pinouts for Fast Ethernet 12-Port PIC

The Fast Ethernet 12-port PIC has a VHDCI connector port on its faceplate (see Figure 93), which accepts the RJ-21 cable supplied with the PIC (see Figure 94).

Table 38 describes the RJ-21 cable pinouts.

Note: RJ-21 pin numbers 25 and 50 do not appear in the table because they are ground connectors.
