Data Communications - Data Interface Pin Outs

Pinout Tables

The following Pinout tables are correct to the best of our knowledge and are reviewed regularly. Always double check pin outs against a second source.

RS-232, RS-422, RS-530, RS-423, RS-449, AUI, RJ-45, EIA Standards and X-21 Pinouts.
 
A pin out is the list of pins for a connector used with a particular interface such as RS-232. The pin out lists the pins and describes the function of each pin.

Note that with ethernet cables, connecting a PC or another ethernet device to a hub, switch or router requires a standard cable. Connecting two devices of the same type such as a PC to a PC or a hub to a switch requires the crossover cable. Some hubs and switches have a dedicated or switchable 'Uplink' port which can be used with a standard cable.
 
Next we will look at testing Data Communications.
