Construction and Usage
RUD-3 is a miniature reader and writer for 13,56MHz ISO/IEC 14443A and Mifare
standard proximity transponders. The reader is supplied from serial USB port which is
also used for communication with the device. The RUD-3 can be used as card enroll
reader for access control system or any other application which requires card reader.
Card can be enrolled straight from the PR Master (version 4.4.6 or above is required) or
using dedicated Roger MiniReader application (version 1.2 or above required). RUD-3 can
also provide a transponder programmer functionality, but in such cases RARC software
(1.4 or above required) should be used. Roger company offers SDK programming
package that enables a programmer to develop customized applications for a specific
requirements.
Functional Description
The RUD-3 can be used in several different scenarios:
as a reader for card enrolling to the RACS access system,
as a reader for card enrolling through Roger MiniReader application,
as a reader and writer for card programming with RARC application,
as a reader and writer used in third party applications using a DLL library provided by
SDK software.
Proximity Cards
The RUD-3 was designed for ISO/IEC 14443A and Mifare proximity cards. Reader can be
configured for reading of:
CSN (Chip Serial Number)
SSN (Card number kept in specified sector of a card)
MSN (Card number kept in location addressable through MAD sector)
The CSN is returned without check sum. The SSN and MSN numbers are designated by
sector number and block within specified sector. Also, for reading of a sector the
adequate Access Key is required. For MSN number the MAD sector is deliberated using
recommended type A key: A0A1A2A3A4A5. By default, reader uses MAD sector assigned
by MSG organization to Roger company (Roger AID number: 5156). The RUD-3 returns
last seven bytes (56 bits) of the card number. Card number is transmitted starting from
the MSB to LSB (reverse order) or from LSB to MSB (normal order) and if required
supplemented with leading zeros. By default reader uses “reverse order” for CSN number
and “normal order” for MSN and SSN numbers.
Examples:
CSN number (Mifare 1K card, “reverse order”)
LSB MSB
0x64 0xE2 0x11 0x46 BCC Manufacturer Data
Reader transmits: 0x00,0x00,0x00,0x46,0x11,0xE2,0x64

SSN or MSN number (reverse order)
LSB MSB
0x11 0x12 0x13 0x14 0x15 0x16 0x17 0x18 0x19 0x1A ...
Reader transmits: 0x17,0x16,0x15,0x14,0x13,0x12,0x11
Cards reading procedure allows for three steps, in each step reader attempts to read the
specified card number (CSN, SSN or MSN). Once the card number is successfully read
the remaining steps are skipped.
The RUD-3 allows to read the CSN from following types of cards:
Mifare 1K
Mifare 4K
Mifare Ultralight
Mifare DESfire
The SSN and MSN numbers can be read from following Mifare cards:
Mifare 1K
Mifare 4K
Note: The RUD-3 supports MAD version 1 sectors only (01-15).
Working with PR Master program
In the list of available readers in the PR Master 4.4.6 control program, RUD-3 readers
connected to the system are displayed. When reading a new card into the system or
modifying a card which had been enrolled earlier, you can use any device displayed in
the list, including the RUD-3 reader.
Working with Roger MiniReader program
The Roger MiniReader 1.2 displays the list of available USB readers connected to the PC.
In order to read a single card, you need to select the Read single card command, and
then put a card close to the reader. When the code is read, it automatically appears in
the Card codes window. The fact of card reading is signaled acoustically however this
feature can be possibly disabled using relevant program’s options (see: Options). If you
use the Read multiple cards command, program will read cards in a loop and insert them
to the Card codes window. In order to interrupt the reading process, you need to use the
Stop reading command. The cards read can automatically be copied to the Clipboard (
Tools > Options > Copy card code to clipboard). By using it, the card codes can be

[4]
moved to other applications or saved to a text file (Tools > Options > Append card code
to file).
Working with RARC program
From the menu list (Options > Port) choose HID1 (RUD-3) … type device, then press OK
button.

[5]
Then RUD-3 must be initialized (Connection > Connect), after this operation device is
ready for use.
Card reading rules and access keys definition are available on the RARC main window for
configuration. For card programming options i.e. MSD, SSN, data sectors, check Card
programmer menu. Configuration changes should be confirmed by pressing a Upload to
reader button.
Working with other programs
Support for RUD-3 reader can also be implemented in other programs, in this case, the
logic of reader handling depends completely on the program’s author. For integration
purposes a RUD-3 software SDK has been released. SDK package contains DLL files
dedicated for USB HID class RUD-3 device, .net software example and programmer
documentation.
LED Signals
The RUD-3 interface is equipped with one signaling LED. This LED is blinking after power
on, and is switched off when the managing software is running. LED indicator turns on
during card reading process.

Reading cards
The proximity card which is to be read into should be put close to the reader so that the
card’s surface is parallel to the reader’s front surface. ISO cards have reading range up
to 6 cm. Nevertheless it is a subject of serious fluctuations depending on the card’s type
and its characteristics. In particular, the range can be seriously reduced for miniature key
fobs. You can assume that in this case you should touch a reading surface with a card.
When the card is read, the computer will generate a short acoustic signal. After that, the
reader is not able to read anything for about a second.
Device Installation
RUD-3 is a USB HID (Human Interface Device Class) device and it’s supported by 32bit
and 64bit versions of Windows 7, Windows VISTA and Windows XP. RUD-3 doesn’t
require dedicated drivers, it’s handled by OS generic USB HID driver. You may connect
the device directly to the PC USB port, driver installation will start automatically.
Note: You should not disconnect a reader while the software working with it is being run.
Violating this rule usually causes that the application controlling the reader will hang up
and you will have to terminate it by using Windows Task Manager.
Programs provided by Roger (PR Master, Roger MiniReader and RARC) automatically
detect that the RUD-3 reader and present it on the list of available devices.
The RUD-3 reader can be connected directly to the controller’s USB socket or using a
cable with magnetic stand provided together with a reader. Using this cable is convenient
because when you use a magnetic stand, the reader can be located at computer’s case or
any other metallic part of a desk or a table.
Optionally, the RUD-3 can be connected to computer by other USB cable of a length not
exceeding 5 meters. However any modifications of original USB cables are prohibited.
The only acceptable way of prolonging USB cables is by using original factory-made
extension cables.
