8 Ethernet
RJ 45-Ethernet connector. Ethernet is a local network with a bus structure for data
communication with a data transfer rate of 10 or 100 megabit per second (Mbps).
9 PROFIBUS/MPI (optional)
You can connect the Box PC to an S7 automation system or to a PROFIBUS
network via the PROFIBUS/MPI port with galvanic isolation. This interface is an
optional product feature.
10 USB
Universal Serial Bus connector. You can use the USB port to connect external de-
vices, for example, CD drives, printers, modems as well as mouse and keyboard.
Older operating systems do not support this port.
11 VGA
You can connect an external VGA monitor to this connector.
12 LPT1
The parallel port connection for devices with parallel port (for example, printer).
13 Keyboard
Connection for a PS/2 keyboard.
Caution
Ensure that you use shielded cables and metal plugs to connect the peripheral
units; if this is not done, the approval for operation will be invalid! Screw down the
plugs of the interface cables to the PC housing by means of a screwdriver. You
thereby improve the electrical shielding.
If expansion modules have been inserted in the PC, there are additional ports.
Please refer to the description of the respective module for their purpose.
