Connecting the instruments
The data interfaces of the 012 Option can be used simultaneously. If this is
done, please be aware that the configuration (baud rate, parity, operating
mode) is the same for both data interfaces. The input currently unused must
be in the BREAK mode to prevent the other interface from being blocked
(RS232C: space, CL: no current).
– Instruments with 20 mA current loop data interfacing are connected to
socket (11).
– Instruments with RS232C data interfacing are connected to socket (12).
(Non-METTLER TOLEDO instrument is DTE).
– If the data transfer is to be triggered by hand ("send on transfer" mode),
handkey (42500) or foot pedal (46278) is connected to sockets (10).
