Sartorius QC150FEG-S, Руководство по эксплуатации, Страница: 104 / 148

General Description of the
Data Interface
General Information
This description has been written for users who wish
to connect their Sartorius QC counting scale, which
has a built-in V24/V28-RS-232C(-S)*) interface port
as a standard feature, to a computer or different
peripheral device.
By using an on-line computer, you can change,
activate and monitor the functions of the scale.
You can also use the interface port to access the
control lines for the over/under checkweighing
function. In addition, an external universal switch
for remote control of various functions can be
connected to the data interface port on the scale.
If you interface an original Sartorius accessory,
such as a Sartorius Data Printer or a similar unit,
with a scale that has the factory-set menu codes,
you do not need to change any settings.
Interfacing Devices with the Scale
Please note that the interface port is electrically
connected to the protective grounding conductor
(protective earth = PE) of the scale housing. The
cabling supplied as accessory components is shielded
and electrically connected on both ends to the cases
of 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 scale.
