Notes for Setting Up Monitors
Please observe the following notes when setting up monitors.
Ensure that the clearance between two monitors in asynchronous operation is
at least 15 cm, otherwise video interference may occur.
Exception: monitors with a mu-metal shield.
Provide sufficient space between the monitor and extraneous magnetic
sources.
Do not set up the monitors in steel shelving or on steel benches. Magnetization
of the surrounding sheet steel can result in false colors or video shifting.
Avoid setting up monitors in the vicinity of transformers, radio transmitters,
magnets and power cables.
The effects of extraneous magnetic fields can be attenuated by using a
mu-metal shield.
Special Conditions when Using Office Monitors
Additionally, you should observe the following notes when setting up office
monitors:
Office monitors with an internally metallized plastic housing should not be used
in an environment subject to electromagnetic interference, because the internal
metal surface cannot be subsequently connected to the external ground bus.
The required isolation of the electronics ground from the housing ground of the
monitor - essential for an environment subject to electromagnetic interference -
is not possible with most office monitors.
You can only use such monitors in conjunction with conventional VGA cables.
Connection to the M7-400 is therefore only possible with limitations, because
you can only cover short distances with these cables.
Connecting Printers
You can connect printers with a serial or parallel interface.
A printer with a parallel interface should be connected with the appropriate
connecting cable (see ordering information) to the IF 962-LPT interface
submodule.
A printer with a serial interface should be connected with the appropriate cable
(see ordering information) to the COM interface submodule.
We recommend the use of Siemens printers.
Note
Only a connection cable with screen grounded at both ends may be used to
connect between an M7-400 component and a printer.
