6. Host communications
FingerVein VIM allows for RS-232 serial communication with the Host. The FingerVein
VIM is permanently listening to the serial channel and will return a response when a
command is received.
The UART0 port corresponds to communications with the Host via RS-232. This
communication is established at 19200 bps, with 8 bits, no parity and one stop bit by
default. The serial frames will consist of ASCII-Hex values according to the frame
format generated by the Bio-OCX controller (see
From the
CFG_HostSerialPort
configuration byte (parameter $1A), however, there are
other alternatives:
• Communication speed can be configured to 9600, 19200, 38400 or 57600 baud. To
do so, the
CFG_HostSerialPort
byte should take the
$90
,
$91
,
$92
or
$93
values respectively.
The
CFG_EventsChannel
parameter ($0D) should take the
$00
value for the FingerVein
VIM to spontaneously transmit Online frames through this channel.
