⚠️ Tools Required

Recommended Equipment

  • 11/32" socket (preferably 1/4" drive) with ratchet
  • 5/16" socket (preferably 1/4" drive) with extension
  • Recommend 10" long extension for sockets
  • Medium size Phillips screwdriver

BAi Readers that ship from us are generally pre-configured. If you think you will need to update the Reader's configuration you will want to also have the equipment from our Configuration Article on hand to avoid a second site visit.

Determine Where To Place The BA-440 DualBeam Reader

BA-440 25ft Range Calibration Diagram

As shown in the figure, the reader should be located about 1.5 car lengths (~25ft) 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 place the reader and decals on the same side of vehicles. If your project will have multiple reader, be sure to determine a side that will work at all reader locations.

Install The Mounting Post

Mounting Post (BA-440-MP) anchor bolts are not supplied. Use appropriate bolts for the material that will serve as the anchor such as a concrete pad.

Unpack Reader

The shipping box for a BA-440 contains both the internal decoder module (BA-440-DEC) and enclosure (BA-440-BOX). Take both out of the shipping box, you may also carefully open the accessories making sure not to drop anything.

Mount baseplate to post

Place the enclosure's baseplate over the top of the mounting post and thread wiring up through the center hole. The lock tab is on the rear of the baseplate, be sure the lock tab faces away from the road. Use four (4) Phillips head self tapping screws from the hardware bag to secure the baseplate to the mounting post.

Seal wiring port in baseplate

Use the 4" putty roll from the hardware bag to seal the opening in the baseplate where the wiring runs. Peel putty from backing and mold around wiring to seal the hole. It is best to have a watertight seal on this opening, use silicone caulk if available. This step is extremely important; if the wiring port is not sealed the outdoor environment will cause the reader to deteriorate. Damage from an improperly sealed reader will not be covered under our warranty.

Mount decoder to baseplate

Unpack and set decoder module on baseplate as shown with the 4 threaded studs passing through the holes on the decoder. Take care not to get fingerprints or dirt on the optics, particularly the reflective wheel. The reflective wheel should face the road with the terminal block at the rear of the baseplate. Use four 5/16" nylock nuts on the threaded studs to secure the decoder module in place. Recommend using a 10" socket extension with the 5/16" socket to tighten the nylock nuts.

Make wiring connections

Strip insulation and connect wiring to the Decoder via the red output board (BA-440-HE-OUTPUT) that is already installed on your new Decoder. Please be sure all power is off during this time to avoid damaging your new equipment.

From left to right:

  1. GND IN - Power Input ground or common input from a 24VDC source
  2. +24V - Power input positive input from a 24VDC source
  3. Data1 - Wiegand 1 (Data 1) communication output to access control system
  4. Data0 - Wiegand 0 (Data 0) communication output to access control system
  5. Comm - Ground or common signal connection to access control system
  6. GND - Ground from reader power input
  7. AuxIn+ - Input for vehicle presence trigger
  8. AuxIn- - Input for vehicle presence trigger
  9. AuxOut+ - Relay Output, Auxiliary, normally open (NO)
  10. AuxOut- - Relay Output, Auxiliary, normally open (NO)
  11. GdRead+ - Relay Output, Gate, normally open (NO)
  12. GdRead- - Relay Output, Gate, normally open (NO)

Recommended wire for power is 18 AWG copper minimum for runs up to 200'.

Optoisolated Wiegand Connection

This is the preferred connection method.

The Wiegand output communication terminals are marked as Data1, Data0, and Common. The normal configuration for Wiegand communication from the BA-440 is optoisolated, where the reader does not supply voltage on the Data0 and Data1 terminals, and Comm does not have a direct connection to the reader ground. Voltage and ground reference is supplied by the access panel or telephone entry system. Use 18Ga shielded copper cable for runs up to 400' and ground the shield at the access system end only.

Once the Wiegand communication is connected to the access system, turn the access system on and measure voltage between Common and Data0, then Common and Data1. There should be approximately 5Vdc present on the Data0 and Data1 terminals. If the voltage is present and accurate, communications should operate fine.

Optional direct wiegand connection

This method of connection is available only if optoisolated (previous step) cannot be used. In some cases the optoisolated wiegand communication cannot be used, generally due to the access panel or telephone entry not providing voltage on the Data0 and Data1 lines.

To change the Wiegand connection from optoisolated to direct:

  1. Move switch S1 to upper position away from the ISO label
  2. Place small jumper wire between Comm and GND terminals

This causes the BA-440 to provide +5Vdc voltage on the Data0 and Data1 lines and connects the Common reference to the reader Ground.

Turn on the BA-440

After confirming all of the above and checking your voltage with a multimeter, turn on the Reader.

You will hear an audible beep and the output relays click as the reflective polygon begins to spin. Within 15 seconds the laser will turn on and the BA-440 will be ready to operate. Ideally, you should use a decal from the property for testing.

Hold the decal as shown and pass it through the laser lines at least two feet away from the Reader. A successful read results in an audible beep from the BA-440 and data transmission out both the serial port and wiegand port. Decal should read out to at least 6' from the Reader. Note: You must wait at least 1 second after a read before the BA-440 will read the same barcode decal again.

Place Dessicant packs on baseplate.

Open Dessicant pouch, place bags and humidity card on baseplate under the receiver circuit board as shown. Desiccant should be changed every 6 months during basic maintenance.

Enclose the Decoder

Set the Hood in place over the top of the BA-440 decoder assembly so that the six studs pass into the six holes on the baseplate. The front window of the hood goes by the reflective polygon as shown. Tighten the hood using the six 11/32" flange nuts from the hardware bag. The hood must be secured using all 6 flanged nuts for a good seal. We recommend threading all 6 nuts finger tight first, then use ratch to tighten approximately 1 to 2 turns more on each nut. Caution: the seal on the reader hood may be damaged if nuts are overtightened.

To prevent unauthorized access a padlock (not included) may be placed through the lock tab at the rear of the BA-440.
