8 Ethernet

RJ 45 Ethernet connection. The Ethernet network is a local network with a bus structure for data communication with data transmission rates of 10 or 100 megabits per second (mbps).

9 PROFIBUS/MPI

Using the potential isolated PROFIBUS/MPI interface, the Box PC an can be connected to an S7 PLC or a PROFIBUS network.

10 USB

Connections for Universal Serial Bus. Using the USB connection, it is possible to connect external devices, such as CD drives, printers, modems or mouse and keyboard. Older operating systems do not support this interface.

11 VGA

A VGA monitor can be connected here.

12 LPT1

The parallel interface serves to connect devices with a parallel interface, e.g. a printer.

13 Keyboard

Connection for a PS/2 keyboard.

Caution

When connecting periphery units, always be sure to use shielded cables and metal connectors to avoid invalidating your operating authorization. Use a screwdriver to fasten the interface cable connectors on the housing of the computing unit. You will thus improve the electrical shielding.

If expansion boards are installed on the computing unit, there are additional interfaces. Please refer to the description of the relevant module for the significance of these additional interfaces.
