Tips
To guarantee the card reader works properly, please read and
obey the notes below.
If the card reader is powered by the controller, the power
supply distance is recommended to be no longer than 100m.
If the distance is longer than 100m, you are advised to power
the card reader by external 12V (range: -%10 ~ +%10) DC
power supply, which is nonswitched and linear.
To guarantee the communication between the controller and
the card reader, you must use RVVP cable above 0.5 to
connect them.
If the card reader is installed outside or in environment easy
to permeable, it is advisable to install a waterproof shield.
If you need to install several card readers, the distance
among them must over 30cm.
To reduce the noise in long distance transmission, the shield
of cable should connect to the GND of both controller and
card reader terminal.
