Wiring
The atomizer is connected to the OUT pad. If the DNA 200 is not being grounded through the
mounting screws, the GND pad should connect to the negative side of the connector. The battery is
connected to the B+ and B- terminals. It is important to use appropriately sized wire when using the
DNA. Too small wire will not perform well, and significantly undersized wire can burn out. The output
wires should be silicone or Teflon insulated only, and at least 14 gauge. The input wire carries less
current, and can be as small as 20 gauge wire if silicone or Teflon insulated.

External component recommendations
The DNA 200 is a self-contained power regulator which does not require external components
for its user interface. However, it does support the use of external interface components if desired.
Fire button:
Use a momentary on, normally open type switch or button. A standard pushbutton switch is
appropriate. The switch is a logic function – all power switching is handled with transistors inside the
DNA module, so the switch does not need to be rated for power. A waterproof or processed sealed
switch is recommended.
Up/Down buttons:
The small onboard buttons labeled UP and DOWN allow the user to increase or decrease the
power level in .1 Watt increments. The onboard tactile switches are waterproof and rated for 300,000
actuations. Please make sure the actuator presses down on the button only, and does not rotate or drag
the top surface. Alternatively, remote normally open type switches or buttons can be attached to the UP
and DOWN mounting holes for customization.
Battery:
The DNA 200 runs from a 3s lithium polymer type battery pack. This type of battery requires
cell-by-cell battery monitoring and balance charging to operate safely. The DNA 200 connects to the cell
taps on the battery pack with a four position JST-XH connector. The tap connector must be connected
for the DNA 200 to run.
