How to Select a Serial Cable
Signaling Standards
Several standards define the signaling over the serial connectors on the router and serial device, the serial cable, and the cable connectors. You can connect a serial device with the following types of connectors to the router serial port:
•
•
•
•
•
•
EIA/TIA-232
EIA/TIA-449
EIA/TIA-530
EIA/TIA-530A
X.21
V.35
Check the documentation that ships with your serial device to determine the type of serial connector on your serial device.
Connector Gender
If pins protrude from the base of a connector, the connector is male. If the connector has holes to accept the pins, the connector is female.
A DTE device typically has a male connector, while a DCE device typically has a female connector.
Examine the serial connector on your serial device to determine its gender.
