6. BCD OUTPUT CONNECTOR
Outputs the weighing data received from the weighing instrument in BCD format, along with the polarity
(+/-) and the data status (stable/unstable and over (E display)).
Using the STROBE signal, the data can be read easily. BUSY input enables the data to be held or
prevents data refreshing during the reading operation.
Contact inputs are RE-ZERO and ON/OFF. They have same function as the key switches on the front panel.
