11. Transmission mode setting
There are four transmission modes of this device: keyboard (PS2) transmis-
sion, serial transmission, USB transmission, and virtual serial transmission.
The keyboard (PS2) transmission mode needs to first pass the device
through the scan setting code, set to the keyboard (PS2) transmission,
and then power off, and the PC end is turned off and restarted before it
can be used normally.
Serial port transmission must use the RS-232 serial communication inter-
face to connect to the device, and can only output data in the serial port
assistant.When set to serial port transmission, you can choose whether to
enable hardware flow control according to your needs.At the same time,
the serial port assistant also needs to choose whether to enable the hard-
ware flow control "RTS/CTS". When the settings of the device and the
serial port assistant are consistent, the data can be transmitted normally.
The USB transfer mode completely simulates the keyboard output, and
any data input can be directly output from the keyboard.
The virtual serial port is a USB serial port transmission mode after con-
necting the device through USB. After setting it as a virtual serial port, you
need to set the port as a virtual serial port in the serial port assistant to
use the virtual serial port function normally. (The port name of the virtual
serial port can be used in the device. Found in the manager's port, which
is "Virtual Com Port").
When the setting of the data transmission mode does not match the port
actually connected, the device will recognize it after the first reading, and
confirm that the data transmission is incorrect for 3 seconds and then
sound an alarm tone.
