Wiegand to USB Virtual COM Port converter

Product Description

WG2USB virtual COM communication convector is designed for Wiegand device communication with its host; The converter support double-way transmission, can transfer Wiegand 26bit/34bit or other Wiegand bit data to USB virtual COM interface, also can transfer data from USB virtual COM to Wiegand 26bit/34bit or other Wiegand bit, Wiegand output 34bit data in default (Wiegand 26bit and other format as optional), and USB output ASCII code (8digit or 10digit ASCII code default) and hex as optional, USB communication protocol based on 9600, N, 8, 1 as standard.

 Technical Parameters

Model: WST-WG2USB (more detail modes as following)

ASCII (decimal number) output modes:

WG2USB-VD26 WG 26bit to USB virtual COM (8 digit decimal number)
WG2USB-VD34 WG 34bit to USB virtual COM (10 digit decimal number) 

Hex output modes:

WG2USB-VH26 WG 26bit to USB virtual COM (3 byte hex number)
WG2USB-VH34 WG 34bit to USB virtual COM (4 byte hex number) 

• Size: 90mm x 45mm x 35mm
• Net Weight: about 30g
• USB driver: CH340/CH341 series USB driver for Windows/Android
• Operating voltage: DC 9V-12V (can get power from access controller direct, but must connect with its GND)
• Consumption current, not more than 30mA
• Transmit distance between converter and device: 
• USB: max 5m(default), Wiegand: max 100m
  Operating temperature range: +5 - +40 °С
• Relative humidity at +15 °С: 80%
• Relative humidity at +25 °С: 90%   

• Communication Instruction:
  Before use converter, must install USB driver (please download from our website or get help from our sales engineer)

To transmit data from converter to the computer through the USB communication interface the following terminal parameters should be set Baud rate first:

Baud rate: 9600, Bit: 8, Parity: no, Stop bits: 1

Connect converter WG port to access controller WG input interface, usually D0 to D0,D1 to D1, GND to GND, +12V to power+12V. Most access controller support WG26bit or WG34bit, but some of them not support both, so in case there have other WG format, please try to check out exact Wiegand bit format and response to our sales engineer for make special upgrade.

WG34bit support max 32 digit data, that is to say 4 byte hex 0xFF 0xFF 0xFF 0xFF (Decimal number 4,294,967,295), so our converter WG output data range must in 0 to 4,294,967,295, over this range there have mistake to show.

When send data from USB virtual COM to Wiegand interface, converter only transfers numbers, and words shall be ignored, for example:

    Computer send data: "123ABC456", converter transfer only: "123456"

    "ABC123ABC456" converter transfer only: "123456"

    "ABCDEFG123456789" converter transfer only: "123456789"

    "http://domain.com/ticket/ID&-abcdef12345678" converter transfer only: "12345678"

    "A1B2C3D4E5F678G" converter transfer only "12345678"

If you have any special requirement, we can made special order for support upgrade when it is acceptable.

In this application, request transfer Wiegand output data to host via our converter, for example Wiegand output RFID reader and any other devices have Wiegand output.

Usually it output Wiegand 26bit or 34bit, and sometimes Wiegand 66 bit, so you can connect this device with the converter Wiegand interface, after set, the converter shall transfer to computer via USB interface.

Most time, RFID reader output Wiegand output as HEX, for example

4 byte number: 1010795316 = (hex) 3C3F8334

WG26 input (hexadecimal) 3F8334

WG34 input (hexadecimal) 3C3F8334

So output ASCII like this:

1010795316 for Wiegand 34bit (3C3F8334)

4162356 for Wiegand 26bit (3F8334)

0D 0A is a carriage return

Wiegand 26bit or 34bit data output transfer to our converter, our converter output max 10 digit ASCII number.

For example: 1234567890, over this limited (such as 11digit), the data shall send out separate.

The converter also support Wiegand 66bit (please remark Wiegand bit when order), and also other Wiegand bit format, please contact our sales engineer for discuss more details when you have project.

In this application, most customers transfer data from their own software (after install USB driver and set Baud rate), for example, send number 1234567890 from computer software to our USB input interface, so our Wiegand output interface shall output data as Wiegand 34bit.

Connect to access control board you can see access control software show a card number: 1234567890.
