BA-440-COM-USB Cable Compatibility and USB Communication Details
The Barcode Automation BAI BA-440-COM-USB is a USB communications cable associated with the BA-440 DualBeam barcode reader. It is intended for installations and service work that require connection through the reader's USB communication interface rather than its RS-232 serial or Wiegand output.
The BA-440 includes a USB communication port that requires driver installation. A compatible terminal application may be used to access reader configuration functions or the internal reader log, depending on the computer, driver, reader firmware, and site requirements.
What This BA-440 USB Cable Does
- Provides a USB communication connection for select BA-440 barcode readers.
- May be used with a compatible computer or supported host device.
- May support reader configuration, diagnostic access, credential-data monitoring, or log-file access.
- Provides the cable associated with the BA-440 USB interface.
- Does not supply the reader's required 24VDC operating power.
- Does not replace Wiegand wiring between the reader and an access control panel.
Compatible With
- Select Barcode Automation BA-440 DualBeam barcode readers equipped with a USB communication port.
- Compatible computers with the required BA-440 USB driver installed.
- Terminal applications such as Tera Term or PuTTY when properly configured for the reader.
- BA-440 service and integration applications approved for USB communication.
Important compatibility warning: The BA-440-COM-USB should not be assumed to work with every USB-equipped device or every BA-440 production generation without verification. Confirm the reader-side connector, computer-side connector, operating system, required driver, reader firmware, and intended communication function before ordering.

Driver and Software Requirements
Barcode Automation states that the BA-440 USB port requires driver installation. Confirm that the correct driver is available for the computer's operating system before beginning installation.
A terminal program may also be required for configuration changes and internal reader log access. Barcode Automation identifies Tera Term as its recommended terminal application and notes that PuTTY may also be used.
The communication cable does not include access control management software. The BA-440 reader and connected access control equipment must be configured as part of the complete system.
USB Communication Settings
The BA-440 supports communication rates of 2400, 4800, 9600, 19200, and 38400 baud. Current manufacturer specifications also list 8N1 and 7E1 data configurations.
The reader and connected computer or host application must use matching settings. Incorrect baud rate, parity, data-bit, stop-bit, driver, or COM-port selections can result in unreadable data or no communication.
Comparison With Other BA-440 Connections
- BA-440-COM-USB - USB communications cable for select BA-440 connections.
- BA-440-COM-SER - separate RS-232 serial communications cable.
- Wiegand output - uses Data 0, Data 1, and common wiring to an access control panel.
- Good-read relay output - provides a dry-contact output and does not carry USB data.
- 24VDC power wiring - supplies reader power and must remain separate from USB communication.
- Ethernet cable - not identified as a direct substitute for BA-440-COM-USB.
Similar Cables Are Not Automatically Interchangeable
A generic USB cable may appear similar but use a different reader-side connector, internal wiring arrangement, cable construction, or supported driver interface. Confirm both connector ends and the BA-440 production configuration before substituting another cable.
BA-440-COM-USB should also not be substituted for BA-440-COM-SER. USB and RS-232 use different interfaces and may require different computer drivers, connectors, and software settings.
Not Intended For
- Powering the BA-440 reader.
- Connecting the BA-440 Wiegand output to an access control panel.
- Replacing the BA-440-COM-SER RS-232 cable.
- Direct Ethernet or network communication.
- Automatic use with BA-220, BA-200, or third-party readers.
- Systems requiring OSDP, RS-485, Ethernet, or another unsupported protocol.
Before Ordering Checklist
- Confirm that the installed reader is a Barcode Automation BA-440.
- Verify that USB is the required communication method.
- Inspect and identify the USB connector on the reader.
- Confirm the required connector on the computer or host device.
- Verify that the correct BA-440 USB driver is available.
- Confirm operating-system and driver compatibility.
- Verify the required communication rate and data configuration.
- Confirm whether Tera Term, PuTTY, or another terminal program will be used.
- Verify the required cable length.
- Confirm that no additional adapter or extension cable is required.
Installation and Service Notes
Turn off power to the reader and connected equipment before attaching or removing cables unless the current equipment instructions specifically permit a live connection. Avoid routing USB communication wiring alongside line-voltage conductors, motors, transformers, or other sources of electrical noise.
Do not apply 24VDC reader power to the USB connector. When the correct driver, connector, communication settings, or software configuration is unclear, installation should be completed by a qualified access control or low-voltage technician.
Technician Note
A failed USB connection does not automatically mean the cable is defective. Check the driver installation, Windows Device Manager or operating-system port assignment, terminal software settings, baud rate, data configuration, connector seating, cable condition, reader power, and reader firmware before replacing the cable.
Product Questions and Answers
What is the BA-440-COM-USB used for?
It is a USB communications cable for select BA-440 reader connections. It may be used for supported credential-data communication, configuration, diagnostic access, or reader log access.
Does the BA-440 USB connection require a driver?
Yes. Barcode Automation states that the BA-440 USB port requires driver installation. Confirm that the correct driver is available for the computer's operating system.
Is BA-440-COM-USB the same as BA-440-COM-SER?
No. BA-440-COM-USB uses the reader's USB interface, while BA-440-COM-SER is for RS-232 serial communication. They should not be treated as interchangeable cables.
Does this cable connect the BA-440 to a Wiegand access panel?
No. A standard Wiegand connection uses Data 0, Data 1, and common conductors. This cable is for the BA-440 USB communication interface.
Are the cable length and connector types confirmed?
No. The exact cable length and reader-side and computer-side USB connector styles were not fully confirmed in public documentation. Inspect the equipment and verify these details before ordering.
Can a generic USB cable replace BA-440-COM-USB?
Not automatically. A generic cable may use a different connector or may not support the required BA-440 communication interface. Compare both cable ends and the reader requirements before substituting another cable.
Can this USB cable power the BA-440 reader?
No. The BA-440 requires a separate 24VDC power supply. Do not use or modify the USB cable as a reader power connection.
What should be checked when USB communication does not work?
Check the USB driver, operating-system port assignment, terminal software, baud rate, 8N1 or 7E1 setting, connector seating, cable condition, reader power, and reader firmware before replacing the cable.
