Para finalizar el ejemplo, y en comparación con el apartado anterior, la comunicación
con el módulo FIM conectado al terminal KBio se realizaría de la siguiente forma:
• Instrucción: Enviar a UART
• Argumento: Byte 1 = $00 (es decir, transmisión a UART0)
• Extra Data:
- La trama real que se manda en Extra Data es, en Hexadecimal y a partir de <ETB>
(incluido):
17266200197E000000040000000000000000000000000000000000000004
• Instrucción CMD_GET_FIRMWARE_VERSION2 a KBio en formato KSP-UDP, trama

A.3. Wiegand Reception
Starting on FW version x61.41.60 on BioMax2, Wiegand reception is also possible. In
order to achieve that, some HW and FW adjustments are required, as explained below.
A.3.1. Hardware configuration
In order to receive a Wiegand frame, we must use terminal block J1 on BioMax2. Please
note that D1, D0 inputs overlap CLS and DAT respectively, formerly related to TTL_1.
Additionally, two signal diodes are required between both pins and the central one,
formerly TTL_1-CLK.
