<strong>R308</strong> <strong>AT</strong> <strong>Command</strong>s<br />
With a few exceptions the S-registers are stored in non-volatile memory and will keep their user<br />
defined settings unless reset to the factory defaults using the “<strong>AT</strong>&F” command. S16, S18, S1A,<br />
S1B, S1D, S39, S40 and S42 are directly accessing volatile I/O registers to prevent memory<br />
cor<strong>ru</strong>ption due to constant I/O access. Registers S17, S19, S1C, S1E, S3A, S41 and S43<br />
represent the non-volatile registers which define the contents of S16, S18, S1B, S1D, S39, S40<br />
and S42 respectively after booting up or reset.<br />
4.1 Recovery of the Factory Default Settings<br />
If the unit seems to be unresponsive to commands on the serial port this is most often due to the<br />
unit having been set into a power-down mode or the set-up for the serial connection having been<br />
altered. To overcome this a feature has been added which performs a factory reset on any module<br />
which seems unresponsive. To factory reset a module, connect it to the PC‟s serial port and<br />
execute the Factory Reset Tool (downloadable from www.telegesis.com). When pressing the<br />
Reset button on the Reset Tool you are prompted to cause a hardware reset to the module by<br />
pulling the module‟s reset line low for more than 100ms (done by pressing the reset button on the<br />
Development Board). Once completed, the factory default settings of the ETRXn module are<br />
restored.<br />
