17.2 Configuring RS-232 Serial Port
Purpose
The RS-232 port can be used in two ways:
• Parameters Configuration: Connect a PC to the DVR through the PC serial port. Device
parameters can be configured by using software such as HyperTerminal. The serial port
parameters must be the same as the DVR’s when connecting with the PC serial port.
• Transparent Channel: Connect a serial device directly to the DVR. It will be controlled
remotely by the PC through the network and the protocol of the serial device.
