3.1.3 RACS Data Transmission Format
When employing RACS transmission format, the PRT62 unit
communicates with its host ACU via the CLK and DTA lines.
Unlike in the Wiegand or Magstripe formats, the PRT62 unit
using RACS format requires an individual address (ID=0…3) to
be set for it during configuration of the reader.
With RACS format, communications between the PRT62 and its
host ACU is bidirectional, hence the ACU is capable of monitoring
it. Also, the reader’s LEDs and the buzzer are controlled by the
host ACU, unless the reader has lost communication with its
host.
When RACS format is used, the IN1 input on the PRT62 is not
used to control the unit’s LEDs (the host unit handles this),
instead, it is dedicated to disable reader’s operation. When IN1 is
shorted with the power supply negative lead, the unit does not
read cards.
Notes: When all LEDs are flashing on the PRT62 reader configured for RACS format it indicate that the unit has
lost communication with the host ACU.
3.2 Stand-alone Operation (OFFLINE Mode)
The PRT62 reader offer two variants of stand-alone operation: Full Stand-alone Mode and Simple Stand-
alone Mode . In both operation modes the reader is capable of providing independent (i.e. autonomous) control
of one door passage.
3.2.1 Full Stand-alone Operation Mode
In this mode, the reader’s CLK and DTA lines are used for communication with a remote XM-2 I/O module and,
optionally, with an additional (secondary) PRT series reader (for two-way door control). The IN1 line operates
as an input and can be configured to various options. The I/O lines on the XM-2 module can be programmed to
have several predefined functions (see settings for C5, C6, C7, C8 and C9 parameters in section Installer
Programming Mode). The Full Stand-alone Operation Mode offers improved security, because it allows for
separating the identification device (i.e. the reader unit) from the actuator element (i.e. the relay operating the
electric lock).
The max. cable length between a PRT reader and an XM-2 module or between a primary and a secondary PRT
reader units is limited to 150 m. For two-way door control, the primary PRT unit needs to be configured for Full
Stand-alone Mode and the interconnected secondary PRT unit needs to be configured for RACS Mode with its
device address set to ID=0.
Note: For Full Stand-alone Mode , the XM-2 I/O extension module connected to the PRT reader has to have
ID=5 address setting (i.e. jumpers JP1 and JP3 closed).
