hint_notice

NOTICE! The General Purpose I/Os are not potential-free and have no protective circuit. Faulty wiring (overvoltage, undervoltage or inverting the wiring when used as serial interface) can result in a damage in the electronics.

During operation as serial interface only LVCMOS levels are allowed to the connector pins. To get a serial RS-232 compliant interface, an external level shifter (LVCMOS/RS-232) is required.

Applying RS-232 levels directly to the pins as well as mixing up the signals RxD and TxD can destroy the camera electronics!

Serial interface wiring (UART)

The following figure shows the wiring of the serial interface with GPIO 1 as camera-side output (TxD) and GPIO 2 as camera-side input (RxD). The GPIO must be configured accordingly (see is_IO()).
