OPTION 012 DATA INTERFACE
INSTALLATION INSTRUCTIONS FOR THE 012 DATA INTERFACE OPTION FOR AE BALANCES
General information
A METTLER TOLEDO AE BALANCE can communicate with other instruments (full duplex) by using the bidirectional 012 Data
Interface. With this option, two standard data interfaces are available: 20 mA current loop and RS232C data interfacing.
You can obtain information about data transfer with non-METTLER TOLEDO instruments and hardware and software definitions
from the data interface description entitled, "The 012 Option bidirectional data interface for AE balances (CL/RS232C)";
Order No. 701323 from METTLER TOLEDO. This description is very strongly recommended if you intend to develop your own
programs for balance control.
Subject to technical changes and to the availability
of the accessories supplied with the instruments.

Opening the housing
This is necessary only if one of the configurations that deviates from the
factory configuration must be set. (Factory setting corresponds to the
METTLER TOLEDO CL standard configuration: 2400 baud/even parity/
send on transfer/RS232C cable shielding: not grounded).
– To open the housing, remove the four corner screws (arrows). Turn
the housing over and lift off cover.
– Remove the four P/C board fastener screws, carefully lift up P/C
board; pull the ribbon cable connector through the housing rear wall.
Configuring the data interface
– Baud rate: set according to the instrument to be connected by using
jumper (1).
– Operating modes: at the factory, all switches on the operating mode
switch (2) are set to the OFF position.

*) Data output: with connection of a printer, the data interface can be
set to "out only" using switch 3 (setting: ON → only data output is
active).
– Cable shielding (RS232C): the factory setting of jumper (4) is on
Pins 2 and 3 (floating). If cable shielding must be placed to the
housing/power supply ground, the jumper must be placed on Pins 1
and 2.
