This chapter provides information on device functions, switches, and power supply.
The terminal controller is designed:
• for operation with the Interflex software IF-6010, IF-6020 or IF-6040.
• to control up to 16 slave terminals.
• to save IN, OUT, absence reason as well as access time stamps (times) as well as events from slave
terminals.
• for offline operation. The terminal controller takes over functions of the Interflex software during offline
operation, e.g., it checks and acknowledges booking authorizations when identification is performed on a slave
terminal.
• to control external devices. Eight relays switch electrical devices up to 3V/ 2A, e.g. electric door openers or the
inputs of alarm systems. Relay functions and switching times can be parameterized via the Interflex software
• to record sensor statuses. Eight inputs record the switching actions of floating feedback sensors. The sensors
can be configured as indicators or counting contacts

Interfaces
The terminal controller is equipped with the following "interfaces":
• Ethernet 10/100 Base T for connection to a host PC with Interflex software
• Ethernet service interface for TELNET or SSH connections
• 1x RS232 host interface as alternative to Ethernet connection
• 1x RS232 host interface as alternative to Ethernet connection
• 1x RS485 host interface as alternative to Ethernet connection
• 3x RS485 BUS interfaces for connection of 16 slave terminals.
Up to 8 slave terminals can be connected and operated on each interface.
• 8 inputs for connection of floating indicators or counting contacts up to 20 Hz
• 8 relays with NO/NC contacts and a switching power of 30V 2A
