OFF means no data is being transmitted or received;
Blinking means data is being received or/and transmitted.
2.2.4 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
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.
