Concentrator connects access control, working time attendance and data collection terminals to the host computer. The C300 concentrator enables operations also when the connection to the host computer is lost. Information checking, access control characterics etc. are handled by the concentrator.

Reliable, efficient and fast structure of the concentrator C300 enables also the management of fairly large systems without difficulties. All operations of the system can be easily monitored and the separated maintenance interface offers assistance in the problem solving.

Advantages & benefits

• Reliable and easy to use
• Efficient buffer memory of over 10 000 events takes care of reliable and fast operation of large systems
• Because of the buffer memory, the system operates also without a constant connection to the host computer
• Several practical functions
• Opto-coupled interfaces and reliable operating protocol are also designed for industrial usage
• Easy and fast connection directly to the serial port of the computer

Features

• Two opto-coupled RS485 terminal networks
• Opto-coupled RS232C
• Host terminal network
• Possibility to connect 1–64 terminals to one concentrator (two terminal networks with maximum of 32 terminals)
• Separated maintenance interface
• Automatic time recording of all terminal events  
• Maintenance of the terminal network and automatic saving of events also on offline
• Action examples: person, order number, work and access time collection and checking
• Eight leads on the front panel to indicate the operating status
• Online validation table in the host computer for modification purposes such as removing persons and adding order
