15VP v4.7.2 Firmware (Flashlight)

By turning the driver quickly on-and-off a number of times, you can access special functionality. Watch for the light show to indicate you’ve reached the click threshold, then stop clicking and keep the driver powered on.

Programming Menu

The programming menu is self-driven. If you enter it by accident, just let it finish (without turning the driver off) and it’ll exit all on its own. Only turn the driver off in the programming menu if you want to change a setting.

Turn the driver off while on a certain menu item to change that setting. When you turn the driver back on, it will re-enter the programming menu at that setting, and display the new value you’ve set.

Programming Menu Details

Number of outputs
The number of outputs the driver will cycle through as you turn it off and on. Most production drivers have 3: low, medium, high.

For each output, choose the brightness from a ramp of 24 possible values. Turn the driver off and on to start ramping. Turn it off and on when you reach the desired output to save it. There is a double-blink at the top of the ramp to indicate when you’ve reached the highest setting, then it rolls back around to the bottom. Ramps twice. If you don’t turn it off at all during those two ramps, no changes are made to brightness.

Mode Memory
Mode memory determines which output slot the driver will power up at during normal use. There are 3 possible values for mode memory. The driver will blink the following number of times to show you which style is currently set:

# BlinksMemory StyleDescription
1NoneAlways powers up at Output Slot #1
2ClassicPowers up at last saved Output, cycles upwards to next slot.
(e.g. 2 -> 3 -> 4 -> 1 -> 2 ->3 -> 4 -> 1)
3HybridPowers up at last saved Output but next cycle starts at 1.
(e.g. 2 -> 1 -> 2 -> 3 -> 4 -> 1 -> 2 -> 3)

Firmware Version

Flashes out the current version of firmware installed on the driver. Different firmwares may behave differently, so this will help you identify which you have so you can find the appropriate documentation.

Flashes firmware numbers in the following pattern:
MAJOR – pause – MINOR – pause – REVISION

So if you click 75x on firmware version 4.7.2 it’ll display:
4 flashes – pause – 7 flashes – pause – 2 flashes

Factory Reset

Resets the driver to its delivered state. A last-ditch attempt to save a problematic driver, or a quick(ish) way to undo undesired programming changes.

Output Levels

For a white power LED (Nichia 219, Cree XP-L, etc) on firmware version 4.7.2, the 24 output levels in the ramp equal approximately the following LED currents:
