There are two main modes of operation available for the PRT-EM reader:
 Terminal Mode (Online Mode)
 Standalone Mode (Offline Mode)
4.1. T
ERMINAL
M
ODE
In this mode 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 PRT-EM 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)
 RS232, EPSO protocol (transactional protocol, reader responses commands received
from the host)
 RS232, cards and individual keys
 RS232, cards and PIN-s
4.1.1. Wiegand Formats
When employing Wiegand transmission format, data is
send to the host using sequences of short pulses
transmitted over CLK and DTA lines. Depending on the
selected version of the transmission format, the reader
can send 26, 32, 34, 42 or 66 bits to the host.
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 shorting them to supply minus. In addition,
whenever card is read or PIN is entered reader activates
momentary LED SYSTEM and buzzer.
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 equal to the full card code.
