Current Loop Output
The current loop output can be used to output data to an A&D printer and a display
unit.
The current loop output is of the passive type and requires an external current source
of 20 mA current. A&D’s printer and display unit can be connected without an external
power source, because they supply the current.
The output terminals do not have a polarity. Each output terminal can be connected to
either the plus or minus inputs of the peripheral unit.
Data Format
The data format is the same as that of the initial setting of F34 of RS-232C data
format.
The current loop output data format is fixed and can not be changed.
Header 2 and the unit selection are common to RS-232C (CF06, CF07).
