I-PLC(Umthwali wentambo yaMandla)
Ewe, i-2-wire system iyafana ne-IP system.
Ngokwesiqhelo kufuneka ibengaphezulu kwe-RVV2*0.75.
Ewe, inokusebenza nabanye nge-SIP.
Ewe, i-290A nganye inokubamba iimonitha ezi-8 2-ingcingo zangaphakathi, kwaye i-290A inokongezwa ngee-290AB ezimbini.Nganye i-290AB inokuqhagamshela kwi-8 2-wire monitors zangaphakathi.
Iqela le-290A * 1 + 290AB * 2 linokusebenza kunye ne-24 2-wire monitors zangaphakathi.Ukuba iimonitha zingaphezulu kwe-24pcs, unokongeza elinye iqela 290A kunye ne-290AB.I-290A inamazibuko amabini e-RJ45 ukuxhuma kwinethiwekhi yokutshintsha ukunxibelelana namanye amaqela.Yile ndlela isikali senkqubo ye-intercom ye-2-wire.
I-290A kunye ne-290AB inikwe amandla yi-adapter ye-DC48V, i-290 master inokunikwa amandla zombini i-adapter ye-DC48V kunye ne-PoE switch, i-290 yekhoboka ayifuni amandla ongezelelweyo.
