7.3. Gateway to Bio-OCX or KPLUS2 electronics
A variety of Kimaldi electronic boards do not provide for integrated IP communication,
since they only have a serial port. BioMax2/KBio2-Online may act as a gateway to
indirectly connect them to a LAN. Moreover, it is a convenient way to enhance
funcionality of BioMax2/KBio2-Online.
7.3.1. Supported electronics, Bio-OCX protocol
The following models can be connected to BioMax2/KBio2-Online:
- Se
rial-xR card: -1R, -4R, 16R (must be configured as Bio-OCX).
- BioMax
, BioMax-FP.
- KBio: normally in its Online version, also Offline.
7.3.2. Supported electronics, KPLUS2 protocol
Starting on FW 0x61.43 KRD13Mv2 readers through KPLUS2 protocol can be
connected. The goal is to implement Online Mifare readers, allowing high-speed read/
write transactions to Mifare cards, over IP.
7.3.3. Communication via Bio-OCX UDP
When using Bio-OCX protocol over UDP (port 5500 on BioMax2/KBio2):
• We contact the peripheral electronics via Send to UART.
• Answers and events are collected through Reception from UART.
• The frame format will be as follows, in binary and without <STX>,<ETX>:
<OPC><NA_high><NA_low><ARG_0><ARG_1>....<ARG_NA><CRC>
• For BioMax, KBio, the recommended connection is through UART0.
Parameter$1A CFG_Serial_Port_Host must take value $99. Maximum frame
length is 912 bytes, suitable to manage the attached FIM module.
• Serial-xR boards may be connected through UART0 or UART1. Parameter$1A
CFG_Serial_Port_Host or Parameter$1B CFG_Serial_Port_Reader must take
value
$98. Maximum frame length is 49 bytes.
• KRD13Mv2 readers may be connected through UART0 or UART1. Parameter$1A
CFG_Serial_Port_Host or Parameter$1B CFG_Serial_Port_Reader may take
values $20, $21 or $22 according to the baud rate. For maximum speed, 38400
baud recommended ($22). Maximum frame length is 49 bytes.
• Frame format for KPLUS2 (KRD13Mv2) is as follows, in binary and without
<STX>,<ETX>:
<OPC><NA><ARG_0><ARG_1>....<ARG_NA><CRC>
