Chapter 1 Introducing the Sensor
Cable Pinouts
Note
Some sensors support 10/100Base-TX (IDS-4210, IDS-4215, and the optional 4FE card) while others
support 10/100/1000Base-TX (IDS-4235, IDS-4250-TX, IPS-4240, and IPS-4255). This only applies to
the copper appliances. The fiber appliances support 1000Base-SX only.
The 10/100/1000Base-TX ports use standard RJ-45 connectors and support MDI and MDI-X connectors.
Ethernet ports normally use MDI connectors and Ethernet ports on a hub normally use MDI-X connectors.
An Ethernet straight-through cable is used to connect an MDI to an MDI-X port. A cross-over cable is used
to connect an MDI to an MDI port, or an MDI-X to an MDI-X port.

shows the 10/100Base-TX (RJ-45) port pinouts.
