:
Multiread
. This enables multiread filtering of the Clock&Data and RS232
inputs.
Multiread filtering is useful for when we have a reader configured in
multiread mode connected to the card (every X time the reader checks the presence
of the card and if it is present it generates an event with the card's identification
information). This mode allows for filtering all the events that correspond to a same
card and only generates events when it varies with the reading data.
Permitted values:
- Bit 0 (LSB): Multiread filter enabled for UART2-UI.
- Bit 1: not in use
- Bit 2: Multiread filter enabled for TTL_0.
- Bits 3-7: not in use
Default value:
- 0x00: Disabled multiread filter.

:
Multiread time-out
. This defines the time required for determining that a
card has left the field of a reader configured in multiread. When this time is up, the
FingerVein Online electronics generates a
event with a null
identification value (refer to
).
Permitted values:
- The time-out value should exceed the reading repetition time.
Default value:
event 4 seconds after the last correct reading.
8.1.5. Digital output timing
For all the parameters described in the table, the configuration value corresponds to
the time in tenths of second that they are to remain enabled:
- When the display is written on (
), the backlighting will be automat-
ically enabled.
Permitted values:
- 0xFF: Permanently enabled.
- 0x01 .. 0xFE: Timing in tenths of a second.
- 0x00: Timing disabled.
Default value:
depending on parameter (see table)
The timings of the internal buzzer can also be configured:
