Wavetronix Click 400 Installation & Quick Start Manual

Click 400 900 MHz Radio
INSTALLATION QUICK START GUIDE
1
Mount the device
The Click 400 mounts over a T-bus for power and communication:
1 If the Click 400 was shipped with the T-bus connector attached, remove the connector
from the module.
2 Snap the connector onto the DIN rail by positioning it over the rail with the male connector
pointing to the right. Hook one arm over the edge of the DIN rail and press down on the
other arm until is snaps into place.
Connect the T-bus connector to the rest of the T-bus by sliding them together until you
3
hear them snap into place.
Mount the Click 400 onto the DIN rail: position it properly over the T-bus connector, hook
4
the lip over the lower edge of the DIN rail, and use a rocking motion to snap the module
into place.

Wire power and communication
If you are using a Click 200 surge protector with the Click 400, power and communication are provided to the Click 400
through the T-bus (see the Click 200 Quicks Start Guide). If you don't have a Click 200 surge protector, use the following
steps to wire power and communication into the Click 400:
1 Plug a T-bus 5-screw terminal block into the first T-bus connector.
Wire DC power (10–30 V) from the power supply into the first
2
screw terminal on the 5-screw terminal block; wire -DC into the
second screw terminal.
3 Connect RS-485 communication (+485, -485, and GND) to
either the remaining three screw terminal on the 5-screw
terminal block or to the screw terminals in the pluggable screw
terminal block on the top of the Click 400 (see labels for cor-
rect wiring).
The front of the Click 400 has one other communication port.

Attach the antenna
The Click 400 has a reversed polarity SMA antenna connector. A whip antenna can be used inside the cabinet, though if it
is inside a metal cabinet, the range will be diminished. An external antenna can also be mounted on the exterior of the traffic
cabinet or up on a pole for maximum range. In that case, it is recommended you use a Click 250 wireless surge protector:
Connect the reversed polarity SMA connector of a coax cable to the Click 400 (antenna must be removed), and connect
1
the N connector to the non-bulkhead end of the Click 250.
Connect the N connector of another coax cable to the bulkhead end of the Click 250, and connect the other end of the
2
cable to the external antenna.
Attach a 12 AWG stranded copper grounding wire to the Click 250, then connect the grounding wire to earth ground.
