Peripheral Card Connections

For information on pin assignments for all I/O cable connections to the Coral
Peripheral Cards, refer to Chapter 5, External Connections for the corresponding tables
for the appropriate Coral Peripheral Card (8/16/24)SFT, (8/16/24)SFT Office,
(4/8)S8F Office, (4/8)S16F Office, (8/16)SFTipx, (8/16)SFTsl and 8F8Ssl.

Line Distances

The FlexAPDL is designed to operate over line distances (see below) using internal
power, supplied by the Coral station circuit. Maximum Line Lengths depend on the
gauge wire used to connect the Coral to the FlexAPDL.
A simple rule of thumb for any gauge wire is that the maximum DC resistance of the
loop be 200 Ohms or less.
