Interface cable

The FIC-SAE modules use synchronous/asynchronous serial interface cables with DB-28 connectors.

Before connecting an FIC-SAE module, identify the line properties and then select the proper interface
cable from the following ten cable options:

z

V.24 (RS232) DTE cable: DB-25 plug at the network end

z

V.24 (RS232) DCE cable: DB-25 receptacle at the network end

z

V.35 DTE cable: 34PIN plug at the network end

z

V.35 DCE cable: 34PIN receptacle at the network end

z

X.21 DTE cable: DB-15 plug at the network end

z

X.21 DCE cable: DB-15 receptacle at the network end

z

RS449 DTE cable: DB-37 plug at the network end

z

RS449 DCE cable: DB37 receptacle at the network end

z

RS530 DTE cable: DB-25 plug at the network end

z

RS530 DCE cable: DB25 receptacle at the network end

All these cables use a DB-28 connector to connect the router, but the connector at the network end
varies with the type of the to-be-connected network.
