Part Number
This is the full model number of the XW-111
Firmware Revision
This is the current product revision of the internal software
Serial Number
This is the serial number of the XW-111. The serial number is also the MAC address of the unit.
Power Supply
This field shows if the XW-111 is currently being powered by batteries or the DC wall transformer. The
battery voltage is periodically measured and an estimate is made of the remaining battery life. If the
module is powered by the DC wall transformer, the voltage is measured with no load on the battery. The
calculations are made for alkaline "AA" batteries with a usable capacity of 2000mAH. When using other
types of batteries or in cold conditions, the displayed estimate may be in error. Depending on the activity,
the battery life estimate may fluctuate (perhaps even increase) as the load current changes. The battery
voltage may recover (increase) when the XW-111 enters low-power sleep mode after a period of high
current operation.
Signal Strength
This indicates the current receive Wi-Fi signal strength. The more negative the number, the less signal is
being received. -30dBm is a strong signal, and -90dBm is a very weak signal.
Reboot
After showing a confirmation message, this button will send a command to reboot the device.
Restore Defaults
After showing a confirmation message, this button will erase all user settings and return the module to its
factory defaults.
