2.8.4 Interface Cable
The Router 1-Port SAE SIC uses a synchronous/asynchronous serial interface cable
with DB-28 connectors for connection.
Before connecting to a port on the Router 1-Port SAE SIC, confirm the line properties
of the interface to select an appropriate cable from the following cable options:
z V.24 (RS232) DTE cable: DB-25 (male) connector at the network end
z V.24 (RS232) DCE cable: DB-25 (female) connector at the network end
z V.35 DTE cable: 34PIN (male) connector at the network end
z V.35 DCE cable: 34PIN (female) connector at the network end
z X.21 DTE cable: DB-15 (male) connector at the network end
z X.21 DCE cable: DB-15 (female) connector at the network end
z RS449 DTE cable: DB-37 (male) connector at the network end
z RS449 DCE cable: DB-37 (female) connector at the network end
z RS530 DTE cable: DB-25 (male) connector at the network end
z RS530 DCE cable: DB-25 (female) connector at the network end
At one end of these cables is a DB-28 connector and at the other end is the connector
that varies with the port at the network side.
