8 IDS control function
The special function of the reader is a
The function description follows.
8.1 IDS connection
The
IDS control function
is connected to the reader module using the
22 module still copies the status of the reader module door lock relay).
The IDS can be controlled either by the
the IDS control relay. The width of the impulse is configurable (see chapter 6.7.3). The
function of the IDS control relay is described in table 15.
Status control
Impulse control
The IDS status is indicated by the third LED of the MREP 78 reader module (located on the
right). In the status control mode the indication is based only on the control relay status, in
the impulse control mode it is given by the I/O Port status. The meaning of the LED color and
the logic of IDS signal at the I/O Port are described in tables 16 and 17:
D3
0 V (GND) signal from the IDS connected to the I/O Port
Other signal (or I/O Port not used) from IDS
Proper connection of the reader module I/O Port with the IDS status signal is required for
the correct function in the impulse control mode!
