Connecting the Printer to the Serial Port
You can also connect your printer to the SIMATIC Box PC using a serial COM port.
You will find information on how to adapt and set your port and which connecting
cable you require in the description of your printer.
Connecting Monitors
You connect external multisynchronous monitors using the standard
VGA connector on the right-hand panel side of the unit. We recommend that you
use a Siemens monitor.
You must switch the SIMATIC Box PC off before connecting the monitor cable. You
will find further information about the connector pinout in Chapter 7.
