8. FingerVein Online electronics configuration
FingerVein Online electronics configuration consists of two parts:
• Parameter array: these are an array of bytes that allow certain machine
characteristics to be defined in terms of function (timings, parameter enabling/
disabling, etc.). They are distributed between the two parts of the electronics (DB
module and UI module). The values that we will normally change are in the UI
module.
Consult Kimaldi for the DB parameters
.
• IP configuration: data required for machine operations in a local area network
(Ethernet).
FingerVein Online electronics is stored in EEPROM memory, which provides it with
around 10,000 read/write cycles. This should be taken into account when managing the
configuration parameters.
