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 recom-
mended 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 configuration features to make sure
the Click 400 is wired and working properly. The
Click 400 has four LEDs that monitor device activ-
ity 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
after 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 installa-
tion will not work until you do this.
Hold the push-button to cycle through modes, then release when the desired mode is reached.
