1D 2D Barcode Scanner , Two Dimensional Code Scanner With High Stability
Name: Two-dimensional Barcode Scanning Module
Model: BT-321
Introduction:
1. Opaque parts of window should not obscure illumination light, aiming light and lens.
2. Apply high wear-resistant material, such as double-sided hard coating material.
3. It is better to make window glass parallel to lens. Window must be perpendicular to the front plate of NT-401 and distance between them should not exceed 1mm. For tilt design , the distance must be more than 1mm. Meanwhile, the distance and tilt angle ensure the light is not reflected into lens by the window glass.
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.
