100 m (max) straight-through or crossover
cable. To prevent ground loops, build this cable assembly with a shielded,
metal-enclosed RJ45 connector on one end and an isolated, plastic-enclosed RJ45
connector on the other end. The metal connector end of this cable must be
placed on the switch and not on the PC.

100 m (max) straight-through or crossover
cable. To prevent ground loops, build this cable assembly with a shielded,
metal-enclosed RJ45 connector on one end and an isolated, plastic-enclosed RJ45
connector on the other end. The metal connector end of this cable assembly can
be placed on either end of the link.

100 m (max) straight-through or crossover
cable. The shield on the controller’s RJ45 connector connects only to a Faraday
cage in the controller; not to the controller’s DC ground. Therefore, the RJ45
connectors are floating and the single point of ground is made at the switch to
which the controller is connected. Build this cable assembly with a shielded,
metal-enclosed RJ45 connector on both ends.

100 m (max) straight-through or crossover
cable. The shield on the CIOC's RJ45 connector connects only to a Faraday cage
in the CIOC; not to the CIOC's DC ground. Therefore, the RJ45 connectors are
floating and the single point of ground is made at the switch to which the CIOC
is connected. Build this cable assembly with a shielded, metal-enclosed RJ45
connector on both ends.

The serial port is not required for process
communications; it is used only for occasional out-of-band switch setup and
management.

The firewall IPD supports up to eight
redundant controllers on its protected side in any combination of M-series and
S-series controllers, and any number of CIOCs.

Use a ring tongue terminal to connect the
ground screw to a suitable shield ground. This connection provides a ground for
the twisted-pair, shielded Ethernet connectors.
