48 CHAPTER 6 CLICK 100
1L (One Loop Speed) Yellow Outputs contact closures for single-loop emulation.
The duration of each contact closure output is based
upon the speed of the detected vehicle (instead of the
duration of the vehicle in the beam). The duration of
each contact output is based on the formula: duration
in seconds = nominal vehicle length in feet / actual
speed in feet per second. The nominal vehicle length
is read from the sensor when this mode is selected.
To set the nominal vehicle length, use the SmartSen-
sor Manager software. The nominal length in feet is
entered in the default loop spacing field.
Autobaud Green (flashing) Autobauds to the connected SmartSensor; also polls
it for loop spacing. These values are saved to flash
memory. While autobauding, the green and yellow
LEDs will flash intermittently, as well as the 16 digital
output LEDs. If the autobauding is unsuccessful, the
LEDs will remain in that state indefinitely. If the auto-
bauding is successful, the yellow LED will flash, then
the device will return to its normal state and default
to the Presence mode.

Troubleshooting
e Click 100 conguration will fail if the communication link is lost or if another device
is active on the communication link (usually the sensor’s native RS-485 port). For example,
the conguration will fail if SmartSensor Manager remains actively connected and com-
municating over the same link as the Click 100. To avoid this issue, connect SmartSensor
Manager to the sensor’s native RS-232 port or simply shutdown SmartSensor Manager dur-
ing Click 100 conguration.
If you choose to use the sensor’s native RS-232 port by connecting to the DB-9 connector
on the associated Click 200, this link will become unreliable if the cable run is longer than
200 feet. Contact Wavetronix Technical Services for assistance if you would like both of the
sensor’s ports to be reliable over distances greater than 200 feet.
One thing to be aware of is that the relays take ve milliseconds to open or close; they physi-
cally cannot react any faster than the messages they receive.
