Communication Ports
The Click 512 provides four communication ports:
˽ RS-485 T-bus connection port
˽ RS-232 front DB-9 connection port
˽ RS-232 top screw terminal connection port
˽ RS-485 top screw terminal connection / front RJ-11 jack connection port
The back of the Click 512 features a 5-position connector that plugs into a T-bus connector
and provides power and RS-485 communication to the device. It also passes RS-485 com-
munication to all other devices on the T-bus. Usually, the RS-485 T-bus connection port is
the primary connection to the SmartSensor HD.
The RS-232 DB-9 port on the front of the module is used when interacting with a computer,
using Click Supervisor or a serial terminal program like HyperTerminal.
