1、 Introduction

Hdc09 converter supports bidirectional conversion between Wiegand signal and RS232 signal

The same device can achieve Wigan - > RS232 and RS232 - > Wigan. The conversion process is automatically identified by signal transmission direction, without manual plug-in interface or other settings. The converter supports the standard WG26 / wg34 Wigan signal format, the input / output of RS232 can be in hex and ASCII format, and the communication parameter is 9600 / N / 8 / 1. If you need to support other private Wigan or RS232 protocol formats, you can provide data for customization.

The converter uses high anti-interference MCU processing chip, built-in watchdog circuit, automatic detection equipment work

Do state, work automatically reset when abnormal, to ensure that the converter will never crash. SMT (surface mount) is used in the whole machine

It can improve the stability of long-term work. After practical application, the converter can work for a long time

No maintenance is required.

2、 Converter interface parameters:

1. RS232 interface communication parameters
Baud rate: 9600 / 115200

Check digit: None

Data bits: 8

Stop bit: 1

2. Wigan interface

The converter supports WG26 and wg34 by default

Others, such as Wigan 35 / 36 / 37 / 42 / 44 / 66, can provide limited support.

The special / private Wigan protocol is customized by users.
