Main mode. This header section sets one of the 3 main mode of operation:
DUMB mode, Automotive mode and the SCRIPT mode.
Output voltage. This header section sets the output voltage of the unit.
Timing Schemes. This header section sets the OFFDELAY and HARDOFF
timers, only available in the Automotive mode.

Configuration, voltage settings

By default, the DCDC-USB-200 module provides regulated 12V output. Should
you need other voltage levels, you can change output voltages by setting
jumpers 2, 3 and 4, see table 1.
After making a jumper change, the DCDC-USB-200 unit needs to be power
cycled in order for the new setting to take effect. NOTE: Finer voltage
adjustments are available via USB settings, see Advanced USB Configuration
manual.

Configuration, Mode of Operation

DCDC-USB-200 has 4 modes of operation. This modes can be changed via
jumpers.
1) DUMB mode. The units acts as a regular DC-DC converter. Only V(In) and
V(out) and GND terminal are required. Unit will convert any input from 6-34V to a
fixed voltage. Default voltage is set to 12V.
2) AUTOMOTIVE MODE. In this mode, the unit acts as as Intelligent DC-DC
converter that is aware of Ignition state. In this mode the unit reads the Ignition
terminal and based on Ignition statuts the unit sends ON/OFF pulses to a
motherboard in order to start or stop. In this mode, two variables can be set:
OFFDELAY and HARDOFF. See Default Timing Schemes for more information.
