What Wiring do I need? Continued…

In this application the BA-220 DualBeam is connected to a Computer

Security System through an RS232 serial port. Barcode decal ID

numbers are programmed into the Computer Security system. When a

vehicle pulls up to the BA-220 DualBeam reader, it reads the decal

and transmits the number to the Security system. If valid, the Security

system opens the gate.

Power Input

For 115VAC - Three wires (Ground, Neutral, Hot) Refer to local

building code for requirements.

For 24VDC - Two wires (Ground and +24VDC) Recommend 18 AWG

Refer to local building code for requirements.
