Th DV21 is capabl of conncting not just our own but also thirdparty dvics. low frquncy connction and control through and V points maks possibl th us of th modul for four dvics. In ordr to mt othr control rquirmnts th 24I lin modul can also b usd. pplication Dscription: WP04 WP08 W06 DT012 030/ 048/ 066/ 084/ 114 Radio Radio F a / b 2TW * Moduls Thirdparty all tation P / PBX Intrcom Radio F a / b ontrol / K arrir Monitoring / Ton ringing V01 24I PU1 4N DV21 1 V100 2 n pplication xampls for intrcom and public addrss systms with Th can b usd for various applications. With P applications, for public addrss through a lincontrolld call station, in addition to th modul also th lin card 24I and th amplifir V100 ar rquird. Th sam applis for us with a signalling systm (PBX) or radio moduls. For intrcom functionality at last on furthr call station is ncssary. This can b anothr thirdparty call station on th sam or a scond modul or a Proom call station on a 4N modul. In standard us, a gat intrcom is ralizd with Proom call stations and th 4N modul. s altrnativ th gat intrcom function can b ralizd with th modul and a thirdparty call station as gat call station. For this a Proom call station connctd ovr th 4N modul and a lin card 24I ar rquird. Hr it must b takn into account that th thirdparty gat call station must hav control points (V and points) to switch th microphon and th call station amplifir. Furthr aras of application ar F control of xtrnal amplifirs as wll as th F connction of xtrnal sourcs (.g. D playr). * TW: Twin Wir Dat: 13.03.2009 1 Pag: 2/5 uthor: H DocumntNo.: DB 2320_01
Function Dscription: Th principl functions ar illustratd in th following block diagram. 24I in inin 1 n p r c h T s t T I l O l N 1 2 n V a b atz t 1 48V ODE t O 5V GND 5V K 24I Nu in inin 1 n T p r c h T s t T I l O l N 1 2 n V a b atz t 4 48V ODE Rr Ou n g BU 48V 0V Block diagram Th has four idntical sts. Th 48 V output is fusd with a cutout fus. If this is dfctiv thn a signal is gnratd through an optocouplr. Th point is rquird for switching on th call station amplifir. To us on lss lin, this can b switchd using a soldr bridg on th backplan ovr th mida/b output transmittr. Th microphon amplifir of a thirdparty call station can b switchd on and off ovr th V point. Ths points ar switchd using th I softwar. Th and V points ar control rquirmnts for thirdparty call stations. Thy ar galvanically isolatd by optocouplrs from th control circuit. Th a/b ar connctd to th output transformr. Th incoming or outgoing analogu F signal is convrtd analogu/digital by th codc. Dat: 13.03.2009 1 Pag: 3/5 uthor: H DocumntNo.: DB 2320_01
