Physical Features
The Click 100 has eight primary and eight secondary contact outputs, which all share a logic
ground (see Figure 6.2).

Communication Port
The back of the Click 100 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 from the Click 100 to all other devices on the T-bus when pressing the Mode
button during configuration (see the On-device Configuration section of this chapter for
more information).
Screw Terminals
The contact closure outputs are wired to a controller, data logger or BIU (Bus Interface
Unit) using the pluggable screw terminals on the top and bottom of the Click 100. The top
screw terminals are labeled 1–8 and represent the primary outputs. Primary 1 (P1) repre-
sents the lane closest to a side-fire SmartSensor and the remaining outputs represent the
lanes as they sequentially get further from the sensor. For dual-loop emulation, the contact
closure outputs must be wired with the primary always leading the secondary (see Figure
6.3).
