Usage Notes
Notes
1. When a sensor is registered for the first time, the Link Manager only starts
contacting the host only when the configuration data and the whole logged data
is collected.
2. The Link Manager starts initiating a connection to the host only after the sensor
makes contact with the Link Manager. The Link Manager initiates contact after
all the data has been collected. The sensor’s Transmit Period dictates how often
the Link Manager attempts to make contact for that sensor.
3. If the Link Manager cannot contact the host, the Link Manager will retry every 5
seconds.
4.
If the sensor’s log buffer is full, it takes 2 minutes for the Link Manager to
collect all of the sensor’s configuration and logged data.
5. The Link Manager has a conversation with one sensor at a time.
6. The Link Manager will transfer a sensor’s data to the host one at a time.
7. Using more than one Link Manager within radio range:
a. A sensor must be registered to just one Link Manager. If the same
sensor is registered to multiple Link Managers, this will cause
confusion to the whole system.
b. Have only one Link Manager in AutoAdd mode at a time.
c. If using 20 or more sensors in the system, consider assigning a unique
radio Hop Table for the Link Manager and the sensors to isolate Link
Managers and sensors. The isolation will help reduce interference from
sensors which will improve performance (reduced collection times and
retries).
8.
Make sure Link Manager’s 900 Mhz antenna is secured tightly.
9. Sensor configuration information can be sent to the sensor via the Link
Manager. When the host sends the sensor configuration when the Link Manger
contacts the host application with sensor data, the Link Manager will highlight
the sensor row in the I/O Status with the color maroon. On the following
contact with the sensor, the Link Manager will send the configuration
information to the sensor at which point the Link Manager will show the normal
background color for the sensor row. It takes two conversations with the sensor
for the configuration information to be transferred.
