Parallel aansluiten Wiegand kaartlezers

Berichtdoor Annie » 03 maart 2014, 23:11

Hello;

Weet iemand of het mogelijk is om twee Wiegandkaartlezers parallel aan te sluiten? Op die manier zouden samen ze via twee gedeelde datalijntjes met de Nodo kunnen worden verbonden. Ik kan dan één kaartlezer (binnen) gebruiken om het alarm te activeren, en de andere (buiten) om het alarm te deactiveren en de deur te openen. Ik weet niet hoe het pulldown-circuit van de kaartlezers in elkaar zit, kan één kaartlezer de beide kaartlezers "laag" maken zonder dat er iets uitbrandt? Heeft iemand daar ervaring mee?

Het gaat om de Wiegandlezers die ook in de shop werden aangeboden, heb ze zelf van eBay:



Hoop dat iemand iets weet, eventueel een andere manier om twee Wiegandkaartlezers op één Nodo aan te sluiten :shock:

Groetjes,

André

Oh dit gaat niet werken............. :oops: Bij twee van die Wiegandlezers aan dezelfde datalijntjes weet de Nodo natuurlijk nooit het verschil tussen beide kaartlezers. Het is voor de Nodo dan niet duidelijk of je nu naar binnen of naar buiten gaat.

Helaas gaat dit dus niet, hoop dat het mogelijk is om door middel van een tweede plugin een tweede wiegandlezer aan te sluiten twee eigen WiredIn pinnen. Bedankt voor het lezen in ieder geval en sorry voor de overlast!
