5. Mount reader Baseplate to mounting post
Place the reader Baseplate over the top of the ounting 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 fro the road. Use four (4) Pan head self tapping security screws fro the
Hardware bag to secure the baseplate to the ounting post. You will need to use the enclosed bit to tighten the ta per resistant screws.
6. Seal wiring port in Baseplate
Once the wiring is run up the ounting post and out through the hole in the Baseplate, you can use the 4” putty roll fro the hardware bag to
seal the opening in the baseplate for wiring. Peel putty fro backing and old around wiring to seal the hole. It is best to have a watertight
seal on this opening, BAI reco ends using silicone caulk or expanding foa if available. This step is extremel important; if the wiring
port is not sealed the outdoor environment will cause the reader to deteriorate.

10. Isolated Wiegand communication
Optoisolated Connection (Preferred)
The Wiegand output co unication ter inals are arked as Data1, Data0 and
Co on. The nor al configuration for Wiegand co unication fro the BA-440
is optoisolated, where the reader does not supply voltage on the Data0 and Data1
ter inals and Co does not have a direct connection to the reader ground.
Voltage and ground reference is supplied by the access panel or telephone entry
syste . Use 18Ga shielded copper cable for runs up to 400’ and ground the
shield at the access syste end only.
Once Wiegand co unication is connected to the access syste , turn the
access s stem on and easure voltage between Co on and Data0, then
Co on and Data1. There should be approxi ately 5Vdc present on the Data0
and Data1 ter inals. If the voltage is present co unications should operate fine.
11. Convert to Direct Wiegand connection if Optoisolated
connection does not function
Direct Connection (if Optoisolated connection cannot be used)
In so e cases the Optoisolated Wiegand co unication 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 fro optoisolated to direct:
1. Move switch S1 to upper position (awa from ISO)
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 Co on reference to the reader Ground.
If you have questions about connecting the Wiegand Interface contact BAI at
800-528-9167.

12. Turn Reader On
Turn Main Power switch On (refer to illustration for location) . You
will hear a short beep and the output relays click as the gold polygon
begins to spin. Within 15 seconds the laser will turn on and the
BA-440 will be ready to operate. Use the enclosed sa ple barcode
or a decal fro the site for testing.
Hold the decal as shown and pass it through the laser lines at least
two feet away fro the reader. A successful read results in a short
beep fro the BA-440 and data trans ission out both the serial port
and Wiegand port. Decal should read out to at least 6’ out fro the
reader. NOTE: You must wait at least 1 second after a read before
the BA-440 will read the same barcode decal again.
13. Test Wiegand output with Verifier
The BA-440-Verifier-Output for the odel BA-440 reader includes a test tool for detecting valid 26
bit Wiegand essages. The Verifier can be used when installed in a BA-440 reader or used as a
handheld Wiegand essage verifier.

13. Test Wiegand output with Verifier, continued
The Green, Red, and Yellow LED indicators are ounted on the rear of the circuit board. Look behind the left side
of the Verifier for the LED indicators as shown here.
The LED's are located in this position in an atte pt to keep the out of direct sunlight. You ay still need to shade
the with your hand if the Sun shines directly on the .
To use the Wiegand verifier function with the odule ounted on a BA-440, turn the "test" switch ON,
which is down toward the arrow. The Green, Red, and Yellow LED's on the left side of the board will
blink once in sequence to show that the verifier is ready. Re e ber that the LED's are behind the
circuit board as shown, you should stand behind the reader to see the clearly.
NOTE: To preserve battery life, the verifier circuit will run for 10 inutes after the switch is ON, then it will go into
power saving ode (hibernation). To reactivate the verifier, turn the TEST switch OFF, wait for 5 seconds, then ON
again. The 3 LED's will blink once in sequence to show that the circuit is live.
Once the TEST switch is ON and you have seen the LED's blink, watch the Verifier LED’s when a decal is read:
No LED’s blinking - 1. Check the voltage on Data 0 and Data 1 to see if there is 5 VDC present. If no voltage is found or if voltage is
less than 3 Vdc, Wiegand essages cannot be sent. Be sure the access syste is connected and turned ON.
2. If voltage easures 5 Vdc, check to see if Wiegand essages are being sent by the reader by observing the
Data0 and Data1 LED’s on the Decoder circuit board. If these are not blinking, no essages are being sent.
3. If Data 0 and Data1 LED’s on the reader are blinking but the Verifier does not then there is no essage output
fro the reader to detect.
Green LED Only blinking - This indicates a 26 bit Wiegand essage is detected with valid parity.
A ber LED Only blinking - This indicates a 26 bit Wiegand essage is detected with bad parity. Usually this eans that the Data 0
and Data 1 connections are reversed, so try reversing the Data 0 and Data 1 leads on the Verifier and see if
the Green LED blinks.
Red LED Only blinking - 1. This indicates that the Verifier is detecting less than 26 bits or ore than 26 bits in a group. Since this is not a
valid essage the Red LED will blink. Check voltages on Data 0 and Data 1 - if either one is 0 or less than 3
Vdc that ay be the proble .
2. If red blinks occur when no Wiegand essage is sent by the reader there ay be electrical interference on the
co unication line. This interference ay be caused by a power line too close to the co unications cable or
a disconnected shield.

13. Test Wiegand output with Verifier, continued
Red and Green blinking - This indicates that both valid essages and electrical interference are detected on the co unications line at the
sa e ti e. So e Wiegand essages will fail if the interference occurs when the essage is trans itted.
As an added feature, the Verifier circuit is battery powered and can be used as a handheld Wiegand 26 bit verifier for any equip ent using
26 bit Wiegand co unication. To use the odule as a handheld device, Turn the ISO switch down toward the arrow, then connect the Data
0, Data 1, and Co on ter inals to the Wiegand co unication line you want to verify and turn the test circuit ON.
Re e ber that the test circuit is live for 10 inutes after you turn the test switch ON, then it will go into hibernation. This is to preserve
battery life if the technician forgets to turn the test circuit off. To restart the test circuit, turn the test switch OFF, wait 5 seconds, then turn back
ON. You should see the Green, Red, and Yellow LED's blink once in sequence to show that the circuit is live.
14. Place Desiccant pack on Baseplate
Open a Desiccant pouch, then place both bags and Hu idity card on Baseplate
under the receiver circuit board as shown. Desiccant should be changed every 6
onths during regular optical cleaning. Every ti e a Model 440 Reader Hood is
re oved check the hu idity card. If all circles are pink the desiccant ust be replaced
before the reader Hood is put back on.

14. Install and seal the reader Hood
Set the Hood in place over the top of the BA-440 decoder asse bly so that the six studs pass into the six holes on the baseplate. The front
window of the Hood goes by the gold polygon as shown. Secure the Hood using the six 11/32” flanged nuts fro the hardware bag. The
Hood ust be secured using all 6 flanged nuts for a good seal.
IMPORTANT: Thread all 6 nuts finger tight first, then tighten onl 1/4 to 1/2 turn more on each nut.
CAUTION: The seal on the reader Hood and hardware ma be damaged if nuts are overtightened.
To prevent unauthorized access a padlock (not included) ay be placed through lock tab at the rear of the BA-440.
