RS-644 Standard Output
The camera adopting RS-422 standard output signal cannot directly connect to RS-644 standard.
When connecting RS-644 standard output, it is required to add a resistance network in camera’s
output location. In order to make sure the normal operation of output circuit, it is required to
connect camera’s ground signal with external ground signal.
9.2.3 Bi-Direction I/O Circuit
The bi-directional I/O can be used as the input signal and output signal, and its internal circuit is
shown below.
