Notes:
(1) Encryption will only be performed when Encryption Enabled (bit 2) and Initial DUKPT
key Injected (bit 1) are set. Otherwise, data that are normally encrypted are sent in the
clear in ASCII HEX format; the DUKPT Serial Number/counter will not be sent.
(2) When DUKPT Keys Exhausted (bit 0) is set, the reader will no longer read cards and
after a card swipe, the reader response will be sent as follows:
[P30]
[P31]
[P35] [Reader Encryption Status]
[P35]
[P35]
[P35]
[P35]
[P35]
[P35] [Device serial number]
[P35] [Encrypted Session ID]
[P35] [DUKPT serial number/counter]
[P35] [Encryption Counter] (optional, OFF by default)
[P35] [Clear Text CRC]
[P35] [Encrypted CRC]
[P35] [Format Code]
[P34]
Format Code
This 4-character ASCII field contains the Format Code. The purpose of the Format Code is to
allow the receiver of this message to know how to find the different fields in the message. The
default Format Code for this reader is “0000”. If any of the properties that affect the format of
the message are changed, the first character of the Format Code will automatically change to a
“1”. The application may change the final three characters, but making such a change will
automatically cause the first character to a “1”.
PROGRAMMABLE CONFIGURATION OPTIONS
The readers have a number of programmable configuration properties. Most of the
programmable properties deal with the Keyboard Emulation mode and other models but some of
the properties deal with the reader regardless of the model. These properties are stored in non-
volatile memory. These properties can be configured at the factory or by the end user using a
program supplied by MagTek. Programming these parameters requires low level
communications with the reader. Details on how to communicate with the reader to change
programmable configuration properties follows in the next few sections. These details are
included as a reference only. Most users will not need to know these details because the reader
will be configured at the factory or by a program supplied by MagTek. Most users may want to
skip over the next few sections on low level communications and continue with the details of the
configuration properties.
