Function Name
Description
Serial Port
No Using: No communication with the device through the serial port.
RS485 (PC): Communicate with the device through the RS485 serial port.
Master Unit: When RS485 is used as the function of the "Master unit", it can be
connected to a card reader.
DM10: Communicate with the device through the DM10 serial port.
Baudrate
There are 5 baudrate options at which the data communicates with the PC.
They are: 115200 (default), 57600, 38400, 19200 and 9600.
The higher the baudrate, the faster is the communication speed, but also less
reliable.
Hence, a higher baudrate can be used when the communication distance is
short; when the communication distance is long, choosing a lower baudrate is
more reliable.
