How to change SenseCam's trigger mode settings:

1. Create a plain text file named BOOT.BAT containing the lines specifying the setting you want (see below). Note that there MUST be a single "comment line" (beginning with a #) at the end of the file.
2. Connect SenseCam to a computer. It should be mounted as a volume.
3. Place the BOOT.BAT file in the SYSTEM folder on SenseCam.
4. Disconnect SenseCam from computer.

Example BOOT.BAT contents:

Sensor-triggering only:

trig 0x1C02

#comment line

Timer-triggering only (uses default timer interval of GAP 30):

trig 0x0200

#comment line

Timer-triggering only, using maximum rate of image capture (GAP 1):

trig 0x0200

gap 1
