Hi, I’m trying to connect a DS-K1104MK card reader with keypad to a DS-KV8113-WME Villa door station. The card reader is powered by its own PSU and connected via RS485 to the door station. The card reader powers up, goes through start up and then shows a flashing blue light which has no definition in the manual. The door station appears in IVMS and the card reader doesn’t, nor does it appear in SADP. I have tried the dip switch settings on the card reader in various different configs, either all 0 and 1, 5 and 8 set to 1 seems to be recommended on line, but nothing works. I can’t see how I can enable RS485 on the Villa through configuration (if that’s required?), nor where to set the Villa RS485 equivalent dip switch settings (again, if required?). Can anyone help me please to get the card reader on line? Thanks.
