6.1 General Information
This description has been written for users who wish to
connect their
KERN 770, GS
and
GJ
balance which has a
built-in RS 232 C interface port as a standard feature, to a
computer or a different peripheral device.
By using an on-line computer, you can change, activate and
monitor the functions of the balance.
In addition, an external universal switch for remote control of
various functions can be connected to the data interface
port on the balance.
6.2 Interfacing Devices with the Balance
Please note that the interface port is electrically connected
to the protective grounding conductor (protective earth =
PE) of the balance housing. The cabling supplied as
accessory components is shielded and electrically
connected on both ends to the cases on the connectors.
This electrical connection may result in interference caused
by ground loops or by transient currents if you have
grounded the housing or connected the protective
grounding conductor for AC power. If necessary, connect an
equipotential bonding conductor to the balance.
