Basic Installation and Setup steps

1. Determine where the Reader will be installed

2. Run wiring to the mounting point for power & communications

3. Pour concrete pad for post mount

4. Secure mounting post and BA-220 DualBeam to the pad

5. Connect power & communications to the reader

6. Place decals on vehicles (the same side the reader will be on)

7. Turn Power Switch On

8. You're up & running

If the BA-220 DualBeam was not set up for your specific installation at the Factory you will have to configure the Reader after it is mounted in place. To do this refer to the Operation and Configuration Manual for details.

Determine where the BA-220 DualBeam will be installed:

18’ to 25’

Approx 1 car length

BA-220 DualBeam

Overhead view of Installation

As shown in this figure, the reader should be located at least one car length (plus a small gap) before the gate. It does not matter which side of the road it is mounted on, as long as the vehicle decals are on the same side. Always locate the reader and decals on the same side of the car.

Copyright 1999-2009, Barcode Automation, inc. 10

Determine where the BA-220 DualBeam will be installed:

In this side view, the important dimension is the height of the reader above the pavement. The general rule of thumb is for the bottom of the reader to be 40” above the pavement where the vehicle tires are located.

Bottom of reader should be about 40” above the pavement

BAI offers a standard mounting post that is 34” high. It is intended to be used on a 6” curb or concrete mounting pad for a total height of

40”. To fabricate a mounting post refer to the appendix for drawings.

6’ read distance

BA-220 DualBeam

The reader should be mounted close to the edge of the road or drive without being in danger of collision with a vehicle. It has a 6 foot reading distance which will extend out across the road or drive. Traffic should not pass by closer than 2 feet from the reader. Protective bollards or barriers around the BA-220 DualBeam is recommended.

Copyright 1999-2009, Barcode Automation, inc. 11

Determine where the BA-220 DualBeam will be

installed:

6’ read distance

In some locations the vehicle drive is very wide, as shown in the illustration above. In these cases, we recommend painting lane lines or stripes to indicate where the vehicle must pass by in order to be read by the BA-220 DualBeam.

Copyright 1999-2009, Barcode Automation, inc. 12

What Wiring do I need?

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

DualBeam Reader.

As a Stand Alone Access Control

115VAC or

24VDC Gate

2 wires for relay contacts

BA-220 DualBeam reads the barcode and if Valid closes relay contacts to Open Gate

Up to 100,000 different label numbers can be programmed

Configure the BA-220 DualBeam with a Laptop Computer

Change access control database with Laptop

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.

Finishing the BA-220 DualBeam Installation

After the Reader is mounted and the wiring is connected, all of the openings in the bottom of the enclosure must be sealed off. Use silicone, RTV, or other sealant to close off the opening in the bottom so it is watertight.

If there is condensation on the laser optics, the Reader may not read barcodes well or at all.

To prevent moisture from entering the enclosure, seal off the opening as described above. Then, open the plastic bag containing the desiccant pouch and remove it. Place the brown pouch and the humidity indicator card flat on the bottom of the unit before closing the door and tightening the latches. The desiccant will absorb moisture from the air in the Reader for a long time before becoming saturated.

Note: Put the desiccant in the reader AFTER the installation is

complete and you are ready to close up the box.

Each time you open the Reader for service immediately check the humidity indicator card. If the humidity card circles are all pink, change out the desiccant pouch and replace it with a fresh one.

BE SURE TO CHECK THE HUMIDITY CARD FIRST WHEN

OPENING THE READER. After the door is opened, the card will react to humidity in the outside air and usually turn pink to show how humid the outside air is. As long as the card is not all pink when you first open the door there is no need to change the desiccant bag.

HUMIDITY INDICATOR

If all 3 blue circles are pink when Reader is first

opened the desiccant should be changed.

Powering Up the BA-220 DualBeam

When testing the BA-220 DualBeam you should have a laptop computer on hand that can communicate with the reader. The reason for this is to take advantage of the diagnostics and test programs that are built in to the unit. For more information on how to communicate

• with the reader refer to the Operation and Configuration Manual.

When the BA-220 DualBeam is powered on:

The Main Power indicator should light up

The +12VDC LED (yellow), +5VDC LED (red) and –12VDC LED

(green) should light up on the mainboard (See pages 16 - 17)

The fan should begin spinning

The gold mirror wheel (also known as the polygon) will spin

Approximately 15 - 30 seconds after the main switch is turned on:

The laser should turn on

The yellow LED on the decoder (Lsr Act) will turn on

The yellow indicator light on the outside of the box will turn on

The BA-220 DualBeam is now ready to read barcodes.

Copyright 1999-2009, Barcode Automation, inc. 25

LED Indicators

Look on the left hand edge of the decoder circuit board (the one that has the gold wheel spinning). There are LED indicators for several functions located in a column. From top to bottom they are:

Gd Read (Green) - will light for approx 1 second when a decal is read

Lsr Act (Yellow) - should be on when the laser is on

Rst Act (Green) - will light when the unit is being reset

Data0 Act (Red)

Data1 Act (Red)

These LED’s indicate when the Wiegand communication lines (data 0 and data 1) are active. When the BA-220 DualBeam is not transmitting, the LED’s should be off. If one or both of the LED’s are on constantly the data line is connected to ground. Remove the wires connected to Wiegand 1 and Wiegand 0 and see if the LED’s go off.

If they do, the wiring may be at fault. Trace the communication wiring and be sure it is connected properly to the access control equipment.

Loop In (Yellow) - will light when the loop input is active

DigLo (Yellow) - will light when data is flowing from receiver board

DigHi (Yellow) - will light when data is flowing from receiver board

Diag (Green) - will light when decoder is in programming mode

Heat (Red) - will light when heater is turned on

Sync (Green) - will light when gold wheel is spinning

Reading a test barcode:

Refer to page 28 for how the barcode must be held for the BA-220

DualBeam to read it. Then, pass the barcode through the laser line.

The green indicator on the outside of the box should light up for approximately 1 second to show that the barcode was read. Also, Gd

Read (green) on the left edge of the decoder circuit board should also light up for 1 second.

Copyright 1999-2009, Barcode Automation, inc. 26

LED Indicators Continued…

Important: The BA-220 DualBeam will not read the exact same barcode number until at least 1 second has passed since the first time it was read. Remember to wait 1 second between reads before trying to scan the same barcode. If you try to read it again sooner, the

BA-220 DualBeam will ignore it. If a different barcode number is read, you will see the green indicator light. The only time you need to wait 1 second between reads is if you have only 1 barcode number to test with.

As you pass the barcode through the laser line watch the two red

LED’s (Data0 Act and Data1 Act) that show the status of the Wiegand data lines. When the barcode is read, both should “flash” or “flicker” red very quickly. These “flashes” indicate that the BA-220 DualBeam has sent out the Wiegand communication pulses for the barcode.

Note: These “flashes” are very fast - to be certain to see them look directly at the indicators and shade them from the Sun if necessary.

At this point the BA-220 DualBeam is ready for operation.
