Control Frame Pinouts

RJ-45 Pinouts

The Encore Control Frame has twelve RJ-45 connectors per slot:

• EN 1 and EN 2 are used for Ethernet connections. They require a patch

cable if connecting to a switch, or a crossover cable if connecting

directly to a PC-compatible.

• COM 2 and the eight connectors labelled SIO 1 to 8 are RS-422/485 serial

connections. There are different pinouts for RS-422/485 depending on

which Encore Control frame is used. See

Encore Control Frame Identifica-

tion on page 54 for help.

• Ports labelled SIO 1 to 4 can be used for RS-232 connections by changing

jumpers on the SIO ISA mezzanine. See

Serial Interface (SIO) Mezzanine

on page 37.

• COM1 CONSOLE connector is a RS-232 serial connection used by either a

terminal or a terminal emulator on a PC-compatible.

See RJ-45 pinout diagrams in Table 10 on page 64.
