1. IMPORTANT NOTES
The PRT-LT reader can be configured for several data output format however the factory shipped
new unit is pre-configured for RACS address ID=0. If required reader can be reconfigured
manually using Memory Reset procedure. Comparing with PRT-EM series access terminals the PRT-
LT series readers doesn’t support standalone operating mode.
Note: If after power up the LED SYSTEM is lit and accompanied with repeated sound it means
that contents of reader’s memory is corrupted. In this case reader must be initialized and
configured from the scratch.
1.1. COMPATIBILITY RULES
Always check the firmware and hardware version for which manual is dedicated. Using wrong
version of manual may cause that device will not behave as described in document.
1.2. ABOUT THIS MANUAL
This manual is dedicated for all versions of PRT-LT readers: with keypad and without keypad. No
matter if the PRT-LT readers have built-in keypad or not they represents the same logical
functionality. The only difference between various types of PRT-LT readers is limited to their
mechanical construction, environment in which they can be installed and keypad which exist in
some PRT-LT units.
2. GENERAL DESCRIPTION
The PRT-LT readers have been designed for use in access control installations to enable user
identification via EM 125 KHz (and compatible) proximity cards and/or PIN-s. The PRT-LT reader
works as a slave unit serving a sole purpose of reading cards/PIN-s then providing subsequent
transmission of such collected data to host ACU for further processing. Reader offers several data
transmission formats including popular Wiegand/Magstripe data protocols.
2.1. FEATURES

(*) – depends on individual reader type
2.2. PROXIMITY CARDS
The PRT-LT was designed for EM 125 KHz proximity cards compatible with EM 4100/4102
transponders. Reader returns card number without check sum bits. Card number is transmitted
starting from the LSB to MSB and if required (it depends on the data output format selected for the
given reader) can be supplemented with leading zeros or reduced on the MSB positions.
2.3. FUNCTION KEYS
Some of the PRT-LT readers are equipped with two (e.g. PRT12LT) or one (PRT42LT and PRT42LT-
BK) function keys: [F1]- marked with door bell icon and [F2] – marked with the light bulb icon. The
function of each function keys depends on the reader’s operation mode.

PRT-LT Series Readers fv1.25 Rev. G 2016-10-08
Page 3 from 17
When in RACS Mode, pressing function key will cause transmission of the relevant code to the
host controller which can further take adequate action (e.g. trigger door bell, light etc.). The host’s
reaction for function key always depends on its configuration.
When in Wiegand or Magstripe modes, pressing the F1/F2 causes following codes send over the
output lines:
For Wiegand:
·F1=C hex
·F2=D hex
For Magstripe:
·F1=FF FF FF FF BC hex (1099511627708 dec)
·F2=FF FF FF FF BD hex (1099511627709 dec)
2.4. OPERATING MODES
The PRT-LT offers following data transmission formats:
·Wiegand 26bit
·Wiegand 32bit, normal mode (from MSB to LSB)
·Wiegand 32bit, reverse order (from LSB to MSB)
·Wiegand 34bit
·Wiegand 42bit
·Wiegand 66bit
·Magstripe (ABA Track II emulation, also called Clock & Data)
·RACS (for communication with PR series of controllers from Roger)
Wiegand Formats
When employing Wiegand transmission format, data is
send to the host using sequences of pulses transmitted
over CLK and DTA lines (which in this case are called
DATA1 and DATA0). Depending on the selected version of
the transmission format, the reader can send 26, 32, 34,
42 or 66 bits to the host.
Note: For card codes which require more bits than the
number of bits available in the selected data transmission
format, reader omits the most significant bits (MSB-s) of
the card code. As a result transmission from a reader is
not the same as full card code.
In Wiegand format, a dual color LED STATUS lights
steady in red, LED OPEN is controlled by IN1 while
buzzer is controlled by IN2. Both inputs (IN1 and IN2) are
triggered by connecting them to supply minus. In addition, whenever card is read or PIN is entered
reader activates momentary LED SYSTEM and buzzer.
Magstripe Formats
When employing Magstripe transmission format, data is
transferred to the host using electric signal waves
transmitted over the CLK and DTA lines. In Magstripe
format a dual color LED STATUS lights steady in red,
LED OPEN is controlled by IN1 while buzzer is
controlled by IN2. Both inputs (IN1 and IN2) are
triggered by supply minus. In addition, whenever card is
read or PIN is entered reader activates momentary LED
SYSTEM and buzzer. Card code is always transmitted
as a whole number

RACS Format
When employing RACS format, the PRT-EM unit
communicates with the host via CLK/DTA lines. Unlike
in the Wiegand and Magstripe formats, the PRT-LT
unit using RACS format requires an individual address
(ID=0…3) to be set during configuration of the reader.
With RACS format, communications between the
reader and the host is bilateral, this allows controller to
monitor communication. The reader’s LED-s and the
buzzer are controlled by the host unit, unless the
reader has lost communication with the host.
Note: When all LED-s are flashing it indicates that
reader lost communication with the host unit.
When in RACS mode triggering of the IN1 disables reading of the card and keypad. This input can
be used for temporary disabling of the reader. The IN2 is not used in RACS mode.
3. CONFIGURING THE READER
3.1. MEMORY RESET
The Memory Reset erases entire contents of the reader’s memory and enables for programming
of the reader’s operating mode.
Memory Reset procedure:
1. Power down the unit
2. Remove all connections from CLK and IN1 lines
3. Connect CLK to IN1
4. Restore power, reader will generate continuous beep
5. While LED OPEN (green) is flashing and accompanied with continues sound
disconnect CLK from IN1, after this step reader’s memory is erased and filled with
default values
6. Wait till LED SYSTEM will start flashing
7. Enter three digits which will configure the reader for the required operating mode, (with
every entered digit reader generates two beeps). Optionally, if the programmed reader
is not equipped with the keypad emulate these three digits using method of multiple
card reading (see details in section below)
8. Once the previous step is completed reader automatically ends the Memory Reset and
enters normal operation

3.2. PROGRAMMING THE PRT-LT READERS WITHOUT KEYPAD
Although some PRT-LT readers are not equipped with keypad still they can be programmed
manually according to the same programming procedures as readers with keypad. The difference
in programming is so that instead of pressing certain keys (like you normally do when
programming readers with keypad) you must emulate keys by multiple readings of the any
proximity card (this card will be latter called Programming Card). So called Programming Card can
be any proximity card – once you read it during programming continue to use it later during entire
cycle of programming. Of course, next time you will perform programming again you can use the
same or another prox. card as Programming Card. For example in order to emulate key [9] you
must read the designated Programming Card 9-times (simply present it to the reader and take it
back 9-times) and then wait approx. 3 seconds for the reader to generate a confirmation signal
(two beeps) which means that series of card readings were accepted as an equivalent of a single
key press and the reader is waiting for the next step of the programming procedure.
Key Emulation Method
[1] Read Programming Card 1-time
[2] Read Programming Card 2-times
[3] Read Programming Card 3-times
[4] Read Programming Card d 4-times
[5] Read Programming Card 5-times
[6] Read Programming Card 6-times
[7] Read Programming Card 7-times
[8] Read Programming Card 8-times
[9] Read Programming Card 9-times
[0] Read Programming Card 10-times
[*] Read Programming Card 11-times
[#] Read Programming Card 12-times
Note: Each time you complete the sequence of multiple readings of the
Programming Card wait for the reader to generate confirmation signal (two
beeps) which will confirm that reader has accepted series of card readings as
the emulation of a single key press.
Example: In order to emulate following programming sequence [*][1][0][ID][#] where ID=113 do
following:
1. [*]: Read 11-times your Programming Card and then wait for two beeps
2. [1]: Read 1-time your Programming Card and then wait for two beeps
3. [0]: Read 10-times your Programming Card and then wait for two beeps
4. [1]: Read 1-time your Programming Card and then wait for two beeps
5. [1]: Read 1-time your Programming Card and then wait for two beeps
6. [3]: Read 3-times your Programming Card and then wait for two beeps
7. [#]: Read 12-times your Programming Card and then wait for two beeps

3.3. INSTALLATION GUIDELINES
·Reader should be installed in such a way to assure physical access to the connection cable
·A new factory delivered unit is configured for RACS address ID=0 however data output
format can be changed whenever required using Memory Reset procedure
·The PRT-LT reader should be mounted near the supervised door on a vertical piece of
supporting structure
·Disconnect power supply before making any electrical connections
·Be aware that when installing the reader directly on the metal type surface card reading
distance will deteriorate
·For installations on a metal surface you can place a non-metallic 10 mm thick spacer (a
plastic/plaster plate etc.) between the reader and the supporting structure
·For installations with two readers to be mounted on the opposite sides of the same wall and
aligned along the same geometrical axis, place a metal plate between them and make sure
none of two readers has direct contact with it (allow min. 10 mm space)
·For best results mount the proximity readers at least 0.5 m apart
·With its relatively weak electromagnetic field generation, reader should not cause any
harmful interference to operation of other equipment. However, its card reading
performance can be affected by other interference generating devices, esp. radio waves
emitting equipment or CRT computer monitors
·If card reading performance of the reader deteriorates (e.g. reduced reading range or
incorrect readings) consider reinstallation in a new location.
