SK-NET Access Control Software is an easy-to-use Windows-based program for managing SK-ACP control panels. The basic software allows up to 200 doors to be connected using a high-speed RS-485 twisted pair bus, and it also allows a single TCP/IP connection. Doors can be controlled and programmed from a central, non dedicated computer. SK-NET-MLD allows the creation of an unlimited number of locations and connection via RS-485, dial-up modem or TCP/IP. The entire system can be connected via TCP/IP if desired. Client/Server licenses are also available that permit software access from multiple workstations. SK-NET is very intuitive for Windows users. SK-NET Explorer uses a familiar format to configure the access control system.
