4-20 Revision: 2.1
4.2.2 Analogue circuit board
The analogue circuit board on the D-23 connects all analogue and digital
inputs and outputs with the digital circuit board of the D-23. The
connection is made from the JP6 connection on the analogue circuit board
to the JP8 connection on the digital circuit board.
The analogue circuit board on the D-23 is equipped with its own
microprocessor, which stores the gain and offset values from the
calibration process.
