1.10Connecting POS (Not Supplied)
Some users may install POS (Point of Sales) to facilitate the sales management. The system saves your time to install the POS system. Just connect your DVR system and POS with a RS232 cable as the following illustration.
Connect the RS232 connectors to both POS and the digital surveillance system’s COM ports respectively.
