A&D AD-4405 manual Current Loop Output, Data Format

Page 73

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 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.

Set f36, f37, f38 and f39 of F-Functions. Please note the initial setting of f37 is disabling the current loop output.

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).

Decimal point (dot or comma) and delimitter (comma or semicolon) can be set by f46.
