Configuration and User Manual
Automatic Selection Threshold
This setting allows you to specify the wireless signal strength (in dBm) before a
configuration change occurs when your
is set to Automatic. As
a wireless signal weakens the Handheld Touchscreen will search the area for a stronger
signal.
Use the slide bar to set the threshold in dBm. By default this value is set to 15 dBm.
HF Channel Energy Scan
Use the HF Channel Energy Scan to determine which HF Channel offers the best
opportunity for successful wireless signal and range for the Handheld Touchscreen and
wireless accessories.
Press the [HF Channel Energy Scan] button to begin the scan.
The display changes to a bar graph, representing all 12 Channels available to the Handheld
Touchscreen. The current channel in use is highlighted in yellow. Select the button beneath
the bottom of a channel to make a new channel selection.
The bar graph constantly updates with the most recent scanned channel data. The bar
graph data offers both a color code and a numeric reference for determining the best
channel for wireless communication.
•
When an HF Channel has low traffic, the bar graph will indicate a small green bar. This
is the optimal channel selection for the Handheld Touchscreen and its wireless
accessories.
•
When the HF Channel has moderate traffic, the bar graph will indicate a blue bar. This
channel selection is acceptable for the Handheld Touchscreen and its wireless
accessories when no other channel is available.
•
When the HF Channel has high traffic, the bar graph will indicate a larger yellow or red
bar. These channels should be avoided.
N o t e :
Higher values require larger differences in signal strengths before the
configuration change will occur. For example, if the Handheld is connected to a
Wireless Access Station and that station signal is currently at -45 dBm; the
Automatic Selection Threshold is set to 15 dBm; then the Handheld would need to
discover another wireless signal that is at least -30 dBm to change.
