Chapter 2 Communication Interface
WSM-QL1601 reading module provides TTL-232 serial communication interface and USB interface
(optional function) to communicate with the host . Through the communication interface, the reading data
can be received .
2.1 Communication Mode Selection
The factory default uses USB-HID mode for communication . Users can switch between
communication port output modes (TTL-232 serial port mode/virtual serial port/USB-HID mode) by
scanning the code setting . When users need to output USB and serial port at the same time, they can select
HID & TTL simultaneous output mode by reading the setting code . When the user switches the
communication mode, he needs to wait for the device initialization to complete before performing related
operations .
Note : When the module is set as a USB virtual serial port and communicates with the host through
this port, the host needs to install the corresponding driver .
