Typicky n\u00edzkonap\u011b\u0165ov\u00e1 PIR \u010didla na 24V – v p\u0159\u00edpad\u011b klidu nen\u00ed na v\u00fdstupu „nic“, v p\u0159\u00edpad\u011b pohybu je tam GND. P\u016fvodn\u00ed zapojen\u00ed (bez Loxone) je takov\u00e9, \u017ee spot\u0159ebi\u010d (nap\u0159. osv\u011btlen\u00ed LED) je trvale p\u0159ipojeno na +24V a bez pohybu nem\u00e1 na druh\u00e9 stran\u011b „nic“ (\u010dili nesv\u00edt\u00ed) a a\u017e p\u0159iveden\u00ed GND (m\u00ednus) p\u0159i pohybu jej rozsv\u00edt\u00ed.<\/p>\n\n\n\n
Loxone DI vstup (a je jedno na \u010dem – Miniserver, Multi Ext Air nebo DI Extension) vyhodnocuje p\u0159\u00edtomnost log 1 jako kladn\u00e9 nap\u011bt\u00ed nad ur\u010ditou \u00farove\u0148 (ka\u017ed\u00fd prvek to m\u00e1 jinak, viz d\u00e1le). Obecn\u011b jde \u0159\u00edci, \u017ee cokoliv nad +10V je bezpe\u010dn\u011b vyhodnocena jako Log1. Ov\u0161em jestli tam nem\u00e1 „nic“ nebo m\u00e1 p\u0159ivedenu GND pro n\u011bj nen\u00ed rozd\u00edl a nedok\u00e1\u017ee tedy nap\u0159. pohyb vyhodnotit.<\/p>\n\n\n\n
Pull up se pou\u017e\u00edv\u00e1 pro to, aby byla na vstupu DI trval\u00e1 log.1 (\u010dili p\u0159ivedeno nap\u011bt\u00ed vy\u0161\u0161\u00ed ne\u017e 9.7V) a v p\u0159\u00edpad\u011b, \u017ee v\u00fdstup za\u0159\u00edzen\u00ed je „nic“, je tam tedy tato log 1. Ve chv\u00edli aktivn\u00edho v\u00fdstupu do LOG.0 (p\u0159ivedena GND) tato „p\u0159ebije“ pull-up a na vstupu je logick\u00e1 nula.<\/p>\n\n\n\n
