4.2.1.
Full Standalone Mode
In this mode the CLK and DTA lines are used for communication with the remote XM-2 I/O
extension module and the second (optional) PRT reader. The second reader enables two-way door
control also it can be used for programming of the main reader. Each I/O line (no mater built-in or
located on extension module) can be configured to various options. The
Full Standalone Mode
offers improved security, because it separates the reader from the attenuators which are used to
control a door lock or other type of equipment.
Note: In
Full Standalone Mode
the optical and buzzer signals occur simultaneously on both
readers. This rules is valid for programming mode and normal operation as well.
The maximum length of the cable run between the PRT-EM reader and the XM-2 module, or
secondary PRT reader is limited to 150 m. For two-way door control the primary reader needs to be
configured for
Full Standalone Mode
while the secondary one (slave) needs to be set for
RACS
address ID=0
.
Note: For
Full Standalone Mode
the XM-2 I/O extension module has to be configured for address
ID=5.
4.2.2.
Simple Standalone Mode
In this mode the CLK and DTA lines are used as
programmable inputs or outputs while the IN1 and
IN2 lines operates always as programmable inputs.
The built-in REL1 operates as output only. Each I/O
line can be configured to have one from several
available functions.
Note:
The CLK and DTA lines may operate either as
inputs or outputs. The function assigned to CLK or
DTA line automatically defines whether this line will
operate as output or input. If configured to be an
output, the CLK or DTA line operates as an open
collector line capable to sink up to 150 mA. Such a
current is usually sufficient to drive relay used for a
door lock control. When necessary, both lines (CLK
and DTA) can be configured to the same output
function and connected together (shorted) for
increased output current (max. 300mA).
