Banner SureCross DX80 Wireless Networks - Manual (Page 19)

High Speed Synching: This mode allows DX80 Nodes to synchronize to the Gateway much faster, which causes more RF traffic from the
Gateway and uses more operating current. We do not recommend using this setting in multiple network environments.
Power Save Gateway: This mode is for applications that require minimizing the power consumption of the Gateway (battery or solar-
powered). This setting causes higher latency in the communications between the Gateway and Node.
Network ID
The Network ID is a unique identifier used to define a wireless network. Assign each wireless network to use a different Network ID. To
set the Network ID, select a Network ID from the drop-down list and click the Set button.
Polling Configuration
Use this screen to set the system-wide Polling parameters. All Nodes set to use Polling use these parameters.
The Polling Config screen allows the users to define custom polling parameters suited for their application. Banner wireless systems use
polling to monitor the status of the RF communications link. If the RF link fails, the system can take precautions to set outputs to defined
states.
1. Click on the Get button to read the system polling parameters from the Gateway. The values populate in the fields and the program
calculates the timeout interval set for the system.
2. In the Number of Misses (%) field, enter the missed packets count from the site survey results (refer to the Site Survey chapter of
the manual, p/n 132607). The program calculates the average timeout frequency. This calculation gives the user an idea of how
often the system may detect a timeout condition based on the system parameters.
3. Fill in your polling interval, max misses, and re-link counts. Click on the Send button to write the parameters to the Gateway.
Choose system polling parameters carefully: higher polling intervals create more RF traffic. With multiple wireless systems within range,
more RF traffic results in a higher percentage of missed communications.
When using battery-powered systems, higher polling rates shorten battery life. Also, the battery-powered devices (FlexPower® devices)
cannot poll faster than one second. Because this is a system-wide parameter, any FlexPower device within the wireless network limits
the polling rate to one second.

Misses The Gateway communicates with, or polls, each
Node to determine if the radio link is active. The
polling rate, or interval, defines how often the
Gateway communicates with each Node. Polling
is always initiated by the Gateway and only veri-
fies radio signal communications. Nodes that fail
to respond are counted against the ‘Maximum Re-link
Count The re-link count is the number of completed
polling messages the Gateway receives from a
Node before a lost RF link is considered re-es-
tablished and normal operation resumes.
Timeout
Interval The Timeout Interval is the total elapsed time
before the system flags an error condition. This
