ascii - characters in the send/received node are interpreted as ASCII. The 8-bit value of the ASCII character is send to the camera. Example: "CL_MODE 15"
ascii+cr  - characters in the send/received node are interpreted as ASCII. A Carriage Return is automatically send after the message. Example: "CL_MODE 15"
hex - characters are interpreted as hex values (00 to FF), they should be separated by commas, do not add "0x". Example: "A0, F2, 42, 33, FF, 1A"
