15.1 Configuring RS-232 Serial Port 
 
The RS-232 is provided by the DS-8600NI-E8 and DS-7700NI-E4 series NVR only.   
Purpose: 
The RS-232 port can be used in two ways: 
•  Parameters Configuration: Connect a PC to the NVR 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 
NVR’s when connecting with the PC serial port. 
•  Transparent Channel: Connect a serial device directly to the NVR. The serial device will be controlled 
remotely by the PC through the network and the protocol of the serial device. 
Steps: 
1.  Enter the RS-232 Settings interface.
