Altum requires 5.2 V DC for operation, with a maximum operating voltage of 25.2 V. The
supply must be able to provide 10 W peak. Power can be provided to the sensor in two main
ways:
●
shared power from aircraft's main battery pack
●
a rechargeable Lithium-Ion battery pack (a two-cell LiPo will provide optimal efficiency).
Ensure the power source conforms to the specifications listed above and can supply the
required voltage at the power port of the camera, accounting for any losses in the wiring.
Input and Output
Nominal IO Voltage*
3.3 V DC
IO Voltage Range*
0.0 V DC to 5.5 V DC
Absolute Maximum IO Voltage*
5.6 V DC
PWM Trigger Expected Range
1.0 ms to 2.0 ms
VIH High-level input voltage*
2.0 V to 5.5 V
VIL Low-level input voltage*
0.0 V to 0.8 V
*All 3.3V HOST IO lines are referenced to ISO GND (Pin 8). To ensure proper operation of
Trigger, Serial, and PPS lines, make sure ISO GND is connected to your host system’s IO
ground. This ground is isolated from the Altum power supply ground and must be connected
for the IO to function properly.
USB Storage and Ethernet
Altum features two high-speed USB 3 ports which support USB 3 compatible devices. Tested,
compatible devices include:
●
Samsung MUF-64BA 128 GB flash drive
●
Edimax Wi-Fi adapters:
○
EW-7811Un
○
EW-7611ULB (requires Altum firmware version 2.0.0 or higher)
●
AmazonBasics USB 3.0 to 10/100/1000 Gigabit Ethernet Internet Adapter
●
Cable Matters USB to Ethernet Adapter (USB 3.0 to Ethernet)
