To remove cards: Place the card on antenna, press module’s button. If
this card has already been added to ZC179 module, the relay will pop 3
times. On the contrary, relay will pop twice and add this card, if this
card doesn’t exist in module’s memory. Please note that ZC179 module
will go into insecurity mode, if user deletes all the cards from its
memory.
To remove all cards: Press module’s button before power on ZC179 module.
The relay will pop 3 times, while all the card records will be deleted.
To open the gate: Make sure the button is released. The relay will be
closed for N seconds, once ZC179 module finds a valid card. For security
reason, relay will only be closed for N seconds, if there is a valid card
in antenna range.
Relay states: Rotate state is defined when N equals to zero. In such state,
the relay will flip once (ON or OFF), every time a valid card is found.You
may set N to zero by releasing the button immediately, when setting up
ZC179 module for the first time.
