Mount the device
1
e Click 400 mounts over a T-bus for power and communication:
1 If the Click 400 was shipped with the T-bus connector attached, re-
move 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 it snaps
into place.
3 Connect the T-bus connector to the rest of the T-bus by sliding them
together until you hear them snap into place.
4 Mount the Click 400 onto the DIN rail: position it properly over the
T-bus connector, hook 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
2
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 Quick-reference 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 rst T-bus connector.
2 Wire DC power (10–30 V) from the power supply into the rst 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 terminals
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 correct wiring).
e front of the Click 400 has one other communication port.

Attach the antenna
3
e 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 trac cabinet or up on a pole for maximum range. In that case, it is recommended you use a Click 250 wireless surge protector:
1 Connect the reversed polarity SMA connector of a coax cable to the Click 400 (antenna must be re-
moved), and connect the N connector to the nonbulkhead end of the Click 250.
2 Connect the N connector of another coax cable to the bulkhead end of the Click 250, and connect the
other end of the cable to the external antenna.
3 Attach a 12 AWG stranded copper grounding wire to the Click 250, then connect the grounding wire to
earth ground.
Use on-device configuration features

Use the device’s conguration features to make sure
the Click 400 is wired and working properly. e
Click 400 has four LEDs that monitor device activity and help you select operating modes, as well as
a push-button, labeled Mode Switch, also used for
operating modes.
1 Autobaud device (see table).
2 Set one of the devices as a server (by default, and
LED activity indicating functions:
Red – Device has power
Blue – Device is a client and can see a server
Blue flash – Device is a server
Green – Device is receiving data
Yellow – Device is transmitting data
aer a reset, the devices are clients) by setting it
in Link Test server mode. When the link test starts,
press the push-button again; the test will end and the device will stay a server. Your Click 400 installation will not work until you do this.
Hold the push-button to cycle through modes, then release when the desired mode is reached.

Autobaud – Release push-button when green light is solid to
autobaud to sensor. Autobauding will set the device as a client.
Link Test (client) – Release push-button when blue LED is solid
to start Link Test mode as a client. The link test can’t be run until
the client and server devices are set to the same RF channel. See
Part 9.
Link Test (server) – Release push-button when blue LED is
blinking to start Link Test mode as a server.
Reset – Release push-button when red LED is blinking to reset to
factory defaults.
