Brief information about bidirectional operation
With the 012 Option, AE balances are equipped with full duplex data interfaces, i.e., the balance can not only transmit weighing
results to a data receiver, but also receive, evaluate and carry out certain control instructions.
These instructions are listed below. A detailed description of these instructions can be found in the data interface description, "The
012 Option bidirectional data interface for AE balances (CL/RS232C)", Order No. 701323 from METTLER TOLEDO.
