Input/Output Connectors
I/O connector
The I/O connector is located at the right side of the unit and used for RS-232C
communication or comparator output.
To use this connector for RS-232C communication and connect to a printer,
see page 25. For comparator output, see page 38.
Note
The RS-232C communication and the comparator
output cannot be used at the same time.
