20 mA Current Loop Interface (C-Box 100 w/INT-30 Accessory Only)
To adapt DS2400N to 20 mA current loop interfaces, it must be connected to a
C-Box 100, which is equipped with an INT-30 (20 mA current loop adapter accessory
board).
The INT-30 converts 20 mA current loop signals into RS232 signals to the scanner.
See the C-Box 100 Installation Manual and the INT-30 instructions.
