DIP-6 settings: The●DIP-6●switches●are●for●DCU●Code●and●Camera●control●settings.
● ● DCU●Code:●●A●unique●identification●of●the●device(range●from●1~3),●it●has●the●same●Code●level●as●Doorstation.●
Total●4●Doorstation●or●3●DCUs(plus●one●Doorstation)●can●be●installed●in●one●system;●for●example,●if●2●DCUs●are●
installed,●maximum●2●Doorstations●can●be●installed●to●the●system.●
● ● Bit-1●and●Bit-2:●DCU●Code●setting.●Note●that●the●DCU●can●not●be●set●to●Master(Bit-1●=●Bit-2●=● OFF ).●Only●one●
Doorstation●can●be●set●to●Master.
● ● Bit-3:●Light●control●mode●/●Unlock●mode●setting:
●» When●control●a●light,●set●to● ON ●to●enable●the●light-on-by-calling●function:●the●light●will●automatically●turned●
on●when●the●visitor●calls●from●the●Doorstation;●set●to● OFF ●to●disable●this●function;
●» When●control●a●lock,●set●to● ON ●to●select●Normally●Closed●unlock●mode,●set●to● OFF ●to●select●Normally●
Open●unlock●mode.
● ● Bit-4:●Camera●quantity●setting.●If●connect●1●CCTV●camera,●set●to● ON ;●set●to● OFF ●for●2●CCTV●cameras.●Multiple●
DCU●must●be●used●when●more●than●2●CCTV●cameras●needed●to●be●connected.
● ● Bit-5●and●Bit-6:●Switching●time●between●the●2●CCTV●cameras(if●connected●2●cameras),●this●setting●become●
