Name: Two-dimensional Barcode Scanning Module
Model: BT-321
Introduction:
The BT321 barcode scanning platform is a 1D barcode and 2D bard code reading product with standard angle, high integration, fast response and high stability.
BT321 can read all kinds of mainstream 1D &2D barcodes.
Ultra-thin and compact product structure, the total thickness of the product does not exceed 29mm, which can greatly adapt to the extreme requirements of the user.
This product can be applied to self-service equipment, payment, access control, and other fields.
Communication Interface:
BT321 device communication interface is: USB HID-KBW, TTL-232, RS232, RS485
1. USB HID-KBW: Based on USB keyboard emulation device, it can be directly connected to PC as a plug-and-play device. No driver is required.
2. TTL-232: The BT321 communicates with the host via a serial port (TTL level), which adapts to most system architectures.
3. RS232: The BT321 can communicate with the host interface via a cable (RS232 level signal).
4. RS485: BT321 can communicate with the host interface through the connection line (RS485 level signal).
Hardware flow control of the serial communication interface is not provided on the BT321.
The default configuration of the BT321's serial communication interface is 115200bps, 8-bit data bits, no parity, and 1 stop bit.
