Wiegand TO RS232 converter

Wiegand-to-RS232 is Bidirectional converter and used to enabling direct connect of the access control card reader to PC.

Wiegand-to-RS232 is Bidirectional converter , The converter can automatically convert Wiegand input from 3-bit up to 42-bit to a formatted ASCII string. When the formatted ASCII string is used as

input to the RS232 port of another MA1405 unit, the formatted ASCII string is reconverted to Wiegand format output .  1 .Specification : 1.1 Communications : 9600 BPS ASYNC, 8bits, 1 Stop , No Parity . 1.2 Wiegand Input /output Format The format of the Wiegand bit stream is shown as follows : 1.3  Rs232 Input / Output Format The format of the RS232 is in the form of 16-byte ASCII string (In Hex format) as follow: The Parity Character P is decoded as follows : 1.4  Command Data : 2 Pin Connectors : The schematic of the MA1405 is shown in the following figure : 2.1  Connecor K1 2.2    DB9 Male 1.    DCD Unused 2.    TX data from converter 3.    RX data from terminal 4.    DTR Unused 5.    Ground 6.    DSR Unused 7.    RTS Unused 8.    CTS Unused  3   Example 3.1  Wiegand TO RS232 Input : Wiegand (26-bit)Output : 16-byte ASCII string from RS232 port 3.2  RS232 TO Wiegand This is a reversed process of Wiegand TO RS232 Input : 16-byte ASCII string to RS232 port Output : Wiegand (26-bit)
