3.2. PROXIMITY CARDS
The PRTxxEM was designed for EM 125 KHz proximity cards compatible with EM 4100/4102
transponders. When in online mode 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.
3.2.1. T5555 and T5557 Cards
The T5555 (Q5) and T5557 cards are special type of EM cards which can be programmed. Using
any PRTxxEM reader together with RARC program it is possible to read and write card’s Chip Serial
Number.
3.3. FUNCTION KEYS
Some of the PRTxxEM series readers are equipped with one or two function keys: [F1] with door
bell icon and [F2] with the light bulb icon. The function of each function keys depends on the
reader’s operating mode and its configuration.
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 to be sent 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)
When PRTxxEM operates in standalone mode (either Full Standalone or Simple Standalone) by
default the F1/F2 keys work as door bell buttons however they can be also configured to control
AUX1/AUX2 outputs. Additionally, in Full Standalone Mode function keys on secondary reader (if
available) have the same functions as assigned for function keys on main reader even when the
main reader has no keys at all.
4. O P E R A T I N G M O D E S
There are two main modes of operation available for the PRTxxEM reader:
Terminal Mode (Online Mode)
Standalone Mode (Offline Mode)
4.1. TERMINAL MODE (ONLINE MODE)
In this mode the reader operates as a slave unit connected to the external access controller. In
Terminal Mode reader transmits collected data (card or PIN) to the host for further processing. The
PRTxxEM 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 CLKD/DTA (addressable format for communication with Roger controllers)
RS232, EPSO protocol (transactional protocol, reader responses commands received
from the host)
RS232, cards and individual keys
RS232, cards and PIN-s
