Extended Basic Mode: This mode requires a Serial Port Adapter (see optional accessories above) to

use. This mode is entered by typing an 'E' Character to enable the writing of parameters then a 'P' for

Programming extended basic features. In this mode all the Basic Mode features apply as well as:

•

P1 Countdown Timer range can be extended

•

P1 and P2 adjustment pots can be bypassed and their values Hard Coded

•

The VTURNON feature can be enabled allowing the DSATX to not send a startup pulse until the

engine is running

•

Parameters set via the Serial Port stay even when power is completely disconnected. They are

stored in Non-Volatile Memory

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.

*Note: modifying the temperature settings to allow higher operating temperatures will void the manufactures limited warranty.

t3 = Time between Computer Shutdown Pulse and +5V Standby OFF. Default = 90s Max, 2s Min

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.

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.
