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!
