$23.00 $30.00

This converter supports multiple working modules, can be used for programming analog keyboards, and supports modifying baud rates.

0x00: Working mode 0 set by software, standard USB keyboard (normal + multimedia) + USB mouse(absolute mouse + relative mouse).

Multiple HID devices will be displayed in the Device Manager.
0x01: Working mode 1 set by software, standard USB keyboard (normal);

One HID devices will be displayed in the Device Manager.
0x02: Working mode 2 set by software, standard USB mouse (absolute mouse + relative mouse);

Multiple HID devices will be displayed in the Device Manager.
0x03: Working mode 3 set by software, standard USB custom HID class devices;

One HID devices will be displayed in the Device Manager.
—————
0x00: Serial communication mode 0 set by software, protocol transfer mode;
0x01: Serial communication mode 1 set by software, ASCII mode;

The serial port receives data and displays it in the text box of the computer, suitable for weighing devices, card readers, payment devices, and so on.

0x02: Serial communication mode 2 set by software, pass-through mode;

Every 8 bytes of serial port data form a data packet, and 8 bytes of data form a keyboard button action

For example, if ‘A’ is pressed, the serial port will send hexadecimal data: 00 00 00 04 00 00 00 00 00 00

Simulate “A” release, then the serial port sends hexadecimal data: 00 00 00 00 00 00 00 00

Simulate “A+SHIFT” to send hexadecimal data through the serial port: 02 00 04 00 00 00 00 00 00

You may use this converter to convert output of serial devices such as RFID readers, Barcode readers, scales, game controllers, etc. to keyboard strokes. The converter cable works with both PC and MAC and identifies itself as an additional HID(Human Interface Device)keyboard and requires no driver installation. The converter cable draws power from USB port and requires no external power supply. Power on pin9 of RS232 is available as an option.

Serial Comms Port: * Baud Rate -1200/2400/4800/9600/14400/19200/38400/57600/115200 Bps(adjustable)
* Parity – None
* Data Bits – 8
* Stop Bits – 1
* Handshake – No
  • Unidirectional, RS232 (input) to USB type-A (output)
  • Data is presented to the USB port as HID compatible keystrokes
  • Ideal for connecting Serial RS232 Barcode Readers, Laser Scanners or Weigh Scales to a USB Type-A connector

– Converts RS232 serial to USB keyboard.
– Available in English, German and French keyboard emulations.
– Eliminates the need to install any device driver or keyboard redirector software. Simply plug it in and any serial input will become a keyboard input
– Draws power from USB port. No external power source required.
– Extended Keyboard controls allows the serial device to control PC functions by sending upper ASCII characters into the serial end of the cable.
Applications
