Usage
With the Configuration Utility running on the PC, the user will install batteries into the sensor to
be configured and set the Power jumper (orange). This will cause the sensor to communicate to
the base and provide the currently configured parameters along with the Sensor’s unique ID
number. This information will be displayed in the Config Sensor tab of the Utility.
The user should change the parameters as necessary, then hit the Set button to send the
changes to the Sensor. The Sensor will receive the new data and store that data in non-volatile
memory.
Once a sensor has been configured, it will begin to operate normally, trying to send data as
programmed and sleeping otherwise, however the PC software will not receive any data from
the sensors until the Configuration Utility is closed. If the configuration is being performed away
from the installation site, the battery or the orange jumper may be removed for shipment, as the
new settings are stored permanently in the unit.
Sensor Placement
With the Base Unit plugged into the PC and the PC Software running, the Sensor placement
phase begins. All the Sensors should be placed at the necessary locations, then the PC
program should be checked to verify which Sensors are within range of the Base Unit.
Alternatively an Installation monitor may be used that pings the base and all repeaters,
providing audible and visual feedback of the signal strength. With this and/or a rough drawn
map of each sensor’s location, the need for repeater placement is easily identified.
After the repeater(s) have been installed, the user will again check the PC program to see an
updated list unseen sensors. If there are still unseen sensors, but they are close to repeaters,
then subtle movement of the sensors could allow them to see the repeater. Refer to the
placement guidelines below. If Sensors are still not able to talk to the base, then additional
repeaters may be required.
Guidelines
Sensors can be mounted in a number of ways by utilizing the reversible hook on the enclosure.
Units may be mounted to the wall or other flat surfaces with screws or industrial double sided
tape. Units can also be strapped to pipes or posts by placing ties through the two slots formed
by the hook. The units may also be hung from a ledge using the hook in the outward position.
Units should not be placed directly on the metal surface (as used by most industrial
refrigerators) unless no other option is available. Mounting on a flat metal surface will
significantly affect the performance of the sensor. Use of the Installation monitor will help
determine the optimal placement of the sensors.
