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.
Communications
For RS232 interface - Three wires (Transmit, Receive, Ground)
Minimum 3 conductor shielded cable 18 AWG
For Wiegand interface - Three wires (Wiegand 0, Wiegand 1, Ground)
Minimum 3 conductor shielded cable 18 AWG
For Optional I/O
Good Read relay - Two wires 18 AWG
No Read relay - Two wires 18 AWG
Loop Detect - Two wires 18 AWG
3 wires for RS232 Signal
