5. Instructions for Programming
5.1 Connecting the System and Processing Data
Processor BIS C-489 reads and writes data of device in sequencer.
The processing unit of data when communicating with the code tag is a one word unit 16 bits, 2 bytes .
( )
To keep data interchangeability, the processing unit should be a unified word unit in a host system if the
sequencer and personal computer are intermingled.
