Connecting to the Computer System

The monitor has been tested and set up at the factory. Therefore, all the remains to be done
before using the unit is to connect all the necessary cables, such as the power supply,
mouse, keyboard and video (VGA) to the connectors provided. These connections must
adhere to EMC regulations.
There are two possible ways of connecting to the computer system. If the cable between the
SCD 1297-K and the computer system is less than 5m long then standard PS2 cables can be
used.
However, it should be noted that these interfaces have not been designed for industrial
environments. External interference can affect the computer system or even put it out of
operation. Use an X27 connection (see Fig. 5, page 50)
