WG2RS485-TH34 WG 34bit to RS485 terminal (4 byte hex number) 

Size: 74mm x 41mm x 29mm

Net Weight: about 30g

Baud rate: 9600 (default, can be change)

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: 

RS485: max 1000m (default), Wiegand: max 100m
Operating temperature range: +5 - +40 °С

Relative humidity at +15 °С: 80%

Relative humidity at +25 °С: 90%

Communication Instruction:
RS485 to Wiegand converter can use for transfer data from RS485 to Wiegand interface, and also transfer data from Wiegand to RS485.

RS485 cannot communication with computer software direct, so need to transfer RS485 data to other communication device such as RS232, TCP/IP, or USB converter or other transfer device. Don’t forget that the converter have default Baud rate, if you request to change to other standard, please contact sales for change firmware before exist factory.

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 RS485 terminal to Wiegand interface (via RS232, USB,and TCP/IP), 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.

1. Transfer Wiegand output data to RS485:

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 RS485 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<CR> for Wiegand 34bit (3C3F8334)

4162356<CR> 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.

2. Transfer data from RS485 terminal to Wiegand output

In this application, most customers transfer data from their own software (after set Baud rate and series COM port), for example, send number 1234567890 from computer software to our RS485 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.
