2N® Helios IP configuration

For 2N® Helios IP Vario please use wiring as follows

Please not that is is necessary to connect +5V output on the card reader module to both W1 and W0 data connectors of Wiegand interface, both through separate 1kOhm resistor.

For 2N® Helios IP Force the connection is similar, GND to GND, W1 to W1 and W0 to W0 between 2N® Helios IP and MiY. Also W1 and W0 have to be connected, but to +12V output of 2N® Helios IP Force card reader. As the voltage is used as pull-up powering of the interface, thanks to the voltage protection of Wiegand interface on 2N® Helios IP Force, higher voltage poses no danger.
