5.5.2.1 I/O Connector Pin Assignment
Attention
The General Purpose IO 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-323 levels directly to the pins as well as mixing up the signals RxD and TxD can destroy the camera
electronics!
