Input/Output Control

General Purpose Input/Output (GPIO)

The camera is equipped with a 6-pin GPIO connector on the back of the case. The connector is a Hirose HR10A-7R-6PB, the mating connector is a Hirose HR10A-7P-6S(73).

Measurement conditions: Opto-Isolated I/O VCC=5V, Rext=1KOhm, Non-Isolated Output: VCC=5V, Rext=330 Ohm, Non-Isolated Input: VCC=3.3V. Measured over operating temperature range (-20˚C to +50˚C ambient temperature), unless otherwise noted.

1—GPIO cable assembly wire colors
2—Dual function pin
3—Open drain output, requires pullup resistor
4—Output low level depends on the output voltage / pullup resistor combination

Power can also be provided externally through the GPIO interface: 12 V nominal (8 - 24 V). Power consumption is 3 W maximum.

If both power sources are connected the camera always uses external power over the GPIO connector.

Note: Some systems, especially those with laptop computers or longer cable lengths, may not provide adequate power through the USB 3.0 cable which could result in intermittent operation. The use of external power through the GPIO is required for these systems.
