Introduction#

This chapter introduces the two interface types, USB and RS232, and lists their related configurations.

RS232#

To connect to the RS232 interface, you need to scan the “RS232” barcode. The default serial port related configuration is: 115200 baud rate, 8 data bits, no check bit, 1 stop bit, and a carriage return and line feed are added by default.

RS232#

RS232 baud rate#

The baud rate sends data from the code reading device to the host at a specified rate. The host must be set to the same baud rate as the code reading device for normal communication. Default=115200.

RS232 word length: data bits, stop bits and parity#

Data bits: You can choose to transmit 7 or 8 data bits. The host must be set to the same data bits as the code reading device for normal communication. Default=8.

Stop bit: The stop bit can be set to 1 or 2. The host must be set to the same stop bit as the code reading device for normal communication. Default=1.

Parity check: A method of checking the character bit pattern. The host must be set to the same parity bit as the code reading device for normal communication. Default=None.

USB#

USB PC#

Scan the following barcode to configure the code reading device into USB PC Keyboard mode. Carriage returns and line feeds are added by default.

USB Keyboard (PC)#

USB COM#

Scan the following barcode to configure the code reading device into USB COM mode, simulating a regular RS232-based COM port. If you are using a Microsoft® Windows® PC, you need to download the driver. If you are using an Apple® Macintosh, the computer will recognize the code reading device as a USB CDC class device.

Note

No additional configuration (such as baud rate, etc.) is required.
