Interface Description
This description has been written for users who wish to connect their Sartorius
balance of the MC1 Series to a computer or other peripheral device using
a V24/V28-RS-232C(-S)*)/423 interface.
By using an on-line computer, you can change, activate and monitor the functions
of the balance and the application programs.
This data interface also provides data output port lines for controlling a remote
display unit for over/under checkweighing. In addition, a universal switch
for remote control of various functions can be connected to the data interface port.
If you interface an original Sartorius accessory, such as a Sartorius Data Printer
or a similar unit, with a balance that has the factory-set menu codes, you do not
need to change any settings.
