Interface cable
The SIC-1SAE uses a synchronous/asynchronous serial interface cable with DB-28 connectors for
connection.
Before connecting to a port on the SIC-1SAE, 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
One end of these cables is a DB-28 connector and the other end is the connector that varies with the
port at the network side.
