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:

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.
