Installation Guide
The first configuration (K version, internal keypad) processes the keypad entries in the reader and then
transmits the data to the host system via the Wiegand data lines. The reader outputs each key as an
ASCII encoded hexadecimal digit. The decoding of the message sent through the Wiegand interface is
the only processing required of the host system. The user interface has been implemented in the most
generic fashion to give the integrator the most flexibility.
The Second configuration (S version, direct connect keypad), the host must scan the keypad directly
using a separate cable.
5 K Version – Internal keypad processing
Parity and Length options must be factory configured. Contact customer service to enable these
options.
5.1 Parity Option
The default does not included parity in the data message. When the parity option is enabled, parity is
added to the total message independent of length. The parity coverage is diagrammed below. Each
parity bit covers exactly one half of the message.
P XXXXXXXX......XXXXXXXXP
EXXXXXXXX...
...XXXXXXXXP
5.2 Length Buffer Keys Option
The length option chooses the number of key entries that will be buffered before the message is sent to
the host. The maximum number of entries is 10 with parity and 11 without parity. When the option is
set for multiple entries the reader has a five (5) second timer that will clear all entries after five seconds
has expired between entries. The length option requires the user to enter the programmed number of
key entries. Upon completion of the last key entry, the message is assembled and sent. Parity is
added if the option is set. This requires the system integrator to configure the reader for the number of
key entries before installation.
5.3 User Interface
The user is able to press keys at any time. Card reads and key entries are independent of each other,
the user is not required to follow any sequence, unless specified by the system integrator. The reader
is equipped to give the user audible, visual and tactile feedback when a key is pressed. The amount of
time is 5 (five) seconds between key entries when the multiple key entry option is used. If the time
expires between key entries, all keys entered are cleared and the user must start the sequence from
the beginning.
5.4 Keypad Message
The keypad message follows a basic format. The entries are transmitted in the hexadecimal
representation. When parity is added, the message format mimics the "standard 26 bit Wiegand
format”. The key that is pressed is represented in Hexadecimal with * represented by A (HEX) and #
represented by B (HEX).
0 = 0000 4 = 0100 8 = 1000
1 = 0001 5 = 0101 9 = 1001
2 = 0010 6 = 0110 * = 1010
3 = 0011 7 = 0111 # = 1011
