is from a Clock&Data port or from a suitably configured UART
(
CFG_Serial_Port_XXXX
parameters to value
$40
or
$41
).
7.2.2. Online readers
Nevertheless, more sophisticated readers do exist. These are those that can generate an
event with the identification code but that, at the same time, allow for two-way
communications with the Host to be programmed.
Within this type are the Kimaldi readers
automatic modes capable of extracting a data sequence from a Mifare or SLE4442 card,
respectively. In this case, the host may issue instructions to manage reader configuration:
• The data frames are sent via the
• The responses are received via the
• Codetag events (ASCII frames) are received via
• The data format is binary, doing without
<STX>, <ETX>.
• Connection via UART0 is established after configuring the
CFG_Serial_Port_Host
to the value
$40
,
$41
or
$42
, according to the baud rate.
The maximum length of the frame is
48 bytes
.
• Connection via UART1 is established after configuring the
CFG_Serial_Port_Reader
to the value
$40
,
$41
or
$42
, according to the baud
rate. The maximum length of the frame is
48 bytes
.
• Moreover, identification events will be treated as in
event, automatic LED and beeper activation, multiread filtering...
7.2.3. Omnikey 55xx Readers
Starting on FW version 0x61.39, Omnikey 55xx Plug&Play RS-232 readers also allow
the
functionality, along with the rest of the features explained in
. Online, bidirectional communication is also supported.
In order to do that, the following parameters must be configured:
• The corresponding UART (
CFG_Serial_Port_Host
or
to value
$30
or
$31
, according to the
).
• We must also activate the corresponding UART bit at the
CFG_Reader_Enable
parameter, and related ones (See
,
• In particular, we must configure
CFG_Multiread_TMO
(also on
), in order to define the appropriate behaviour of the multiple
events, when the card is permanently placed on the reader.
