Online mode:
RS232 EPSO v2
protocol
Reader is connected to the host through RS232 serial
interface. The host exchanges data with the reader
using
EPSO v2 protocol
.
10x
Online mode:
26 bit Wiegand
Reader operates as a slave unit connected to the
host controller that requires specific Wiegand data
transmission format.
11x
Online mode:
34 bit Wiegand
12x
Online mode:
42 bit Wiegand
13x
Online mode:
66 bit Wiegand
14x
Online mode:
32 bit Wiegand
(no parity)
15x
Online mode:
32 bit Wiegand reverse
(from LSB to MSB, no parity)
Note: For Wiegand data formats the third digit of the operating mode code (marked by “x”) specifies the
method which reader employs when transmitting PIN-s or keys. For details regarding methods of PIN
transmission refer to table below.
PIN/keys transmission options
X
Description
Details
X=0
1-10 digits long PIN,
transmitted in BCD
format
Each key pressed is buffered in reader’s memory; with a press of a [#]
key reader transmits entire PIN code. The PIN code is transmitted as a
BCD coded number.
X=1
1-12 digits PIN,
transmitted in binary
format
Each key pressed is buffered in reader’s memory; with a press of a [#]
key reader transmits entire PIN code. The PIN code is transmitted as a
binary number.
X=2
Each key pressed is
transmitted separately
as 4-bit number plus
2 control bits
Each key pressed is immediately transmitted to the host controller as a
sequence of 6 bits (EXXXXP) where XXXX represents the code of the
pressed key supplemented by two control bits (E and P). The E
represents the even bit calculated from the first half of a transmitted
code where P represents the parity of a second half of the bit stream.
This format is compatible with HID 5355 series readers, option “with
parity”. Key coding as in Table B (below).
X=3
Each key pressed is
transmitted separately
as 4-bit number
Each key pressed is immediately transmitted to the host controller as a
sequence of 4 bits (XXXX) which represent the code of the pressed key,
no control bits added. This format is compatible with HID 5355 series
readers, option “without parity”. Key coding as in Table B (below).
X=4
Each key pressed is
transmitted separately
as 8-bit number with
parity
Each key pressed is immediately transmitted to the host controller as a
sequence of 10 bits (EXXXXXXXXP) where XXXXXXXX represents the
code of the pressed key supplemented by two control bits (E and P). The
E represents the even bit calculated from the first half of a transmitted
code where P represents the parity of a second half of the bit stream.
Key coding as in Table A (below).
X=5
Each key pressed is
transmitted separately
as a 8-bit number
without parity bits
Each key pressed is immediately transmitted to the host controller as a
sequence of 8 bits (XXXXXXXX) where XXXXXXXX represents the code of
the pressed key supplemented by two control bits (E and P). The E
represents the even bit calculated from the first half of a transmitted
code where P represents the parity of a second half of the bit stream.
Key coding as in Table A (below).
