What Wiring do I need?

For most applications, there are three basic ways to use the BA-220

DualBeam Reader.

In this situation, the BA-220 DualBeam reader acts as the Access

Control. Barcode decal numbers are programmed into the reader and

set to grant or deny access based on the individual number. The

reader can be programmed via a laptop computer or an optional

modem tied into a phone line. When vehicles pass by the BA-220

DualBeam reads the barcode and checks to see if that number has

access. If access is granted the Good Read relay contact closes to

open the gate. If access is denied the gate does not open and an

optional No Read relay contact will close that can be connected to an

indicator or alarm to indicate that access is denied.

Wiring Needed:

• 2 conductor 18 AWG from reader to gate operator

• 3 conductor for AC power connection (follow local electrical codes)

• 2 conductor 18 AWG for 24VDC power connection

Optional:

Shielded 3 conductor 18 AWG for connecting RS232 serial port of

reader to computer. Distance should not exceed 100 feet.
