Connecting Digital Inputs and Outputs
The activation and evaluation of the inputs and outputs is carried out using the ReaderStart V3 software, with
the DLL supplied or by access to the reader protocol.
Figure 6 Allocation of the GPIO interface cable
The digital inputs and outputs are provided via a 12-pin sockets in A-coding with M12 connection threads.
The inputs are electrically isolated from the power supply of the reader and can be operated irrespective of
the polarity of the input signal. For this reason, there is a common pin for the inputs (INP_CMN). The
connection variants for the inputs are shown below.
If the electrical isolation is not required, the power to the input can also be supplied by the reader via pin 6
and 7 see 9.2.1 GPIO.
The outputs are also DC-isolated from the power supply of the reader and have a common pin (OUT_CMN).
If the electrical isolation is not required, the power supply can also be taken directly from the reader.
NOTICE
Risk of malfunction!
Ź Note that the load per channel is limited to a maximum of 0.5 A, and the total load across
all the channels must not exceed 1.5 A. If the auxiliary voltage of the GPIO port of the reader
is used, the load can be 1.1 A as a maximum. The inputs and outputs are designed for 30 V
DC max.
Ź For further information, see the reader data sheet.
Ź Bear in mind that LPS or NEC Class 2 classified power supplied units can be used for the
operation of the outputs
