Advanced Mode: This mode is simply going in and hard-coding various settings. Advanced setting
adjustments include button press duration, deep-sleep disable, temperature range adjust,* etc. These
settings are accesses by using the “Get” and “Set” commands. See the Serial Port Section for more
information.

Features Explained
3.5.1. Startup/Shutdown Sequencer
The DSATX is has the ability to turn on and turn off the computer via the JP1 pins G1,G2 connection.
The DSATX is has the ability to turn on and turn off the computer via the JP1 pins G1,G2 connection.
Connecting a 2-pin jumper wire will allow the DSATX to tell the motherboard to turn on and turn off by
simulating a power button press. The DSATX knows if the motherboard is on or off and will only send the
startup pulse if off and the shutdown pulse if on. This way the DSATX does not get into a weird state where it
turns the computer on/off when it wasn’t suppose to due to the user issuing a manual startup/shutdown.
