CHAPTER 28 CLICK 400

Physical Features

The Click 400 has several communication ports, as well as features for configuration.

Figure 27.2 – Diagram of the Click 400

Communication Ports

The back of the Click 400 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 400 to all other devices on the T-bus.

The top of the device has a pluggable screw terminal block that features four terminals—one

-485, one +485 and two grounds—for wiring RS-485 communication. This screw terminal

block can be removed for easy preinstallation wiring. It will not be necessary, however, to

wire RS-485 through the screw terminal block if the device is connected to a T-bus with

uninterrupted RS-485 communication.

The front of the device has a DB-9 connector for RS-232 communication. Connect a straight-

through cable from this port to a computer to configure the device using Click Supervisor.

Any data on one port will be transmitted simultaneously on all other ports.

Antenna

The Click 400 has a reversed polarity SMA antenna connector. An external antenna can be

mounted on the exterior of the traffic cabinet or up on a pole for maximum range. A whip

antenna can also be used inside the cabinet. If the antenna is installed inside a metal cabi-

net, the range will be diminished.
