interface used to control auxiliary equipment, e.g. PTZ devices.
The RS-485/422 serial port can be configured in the following port modes:
• Bidirectional RS-485 half-duplex port for data transmission using
two wires, one combined RX/TX pair.
• Bidirectional RS-485 full-duplex port for data transmission using
four wires, one RX pair and one TX pair.
• Unidirectional RS-422 port for transmitting or receiving data using
two wires, RX- or TX pair.
• Bidirectional RS-422 full-duplex port for data transmission (point-to-point) using four
wires, one RX pair and one TX pair.
