APPENDIX #6 - RS232 REMOTE PROTOCOL

The RS232 / Alarm input allows you to control the DVR system from your PC. In order to 
achieve this, you will require an RS232 COM Port communication program installed on your 
PC. There are many of these software programs available on the internet, some of which are 
free.

For Pin Connection instructions, please refer to Appendix # 4

The remote connection on the DVR uses 8 data bits, 1 start bit, and 1 stop bit, no parity. 
Below is a list of the control codes.
