CONNECTING A CM6800
The CM6800 external alarm files must be set up correctly. You must set auto reset on the CM6800 to acknowledge alarms.
Refer to the CM6800 Installation/Operation manual.
To connect a CM6800 to a DX9200 recorder:
1. Connect a null modem cable from the recorder’s COM 1 or COM 2 port to COM 1 (RS-232) on the CM6800.
2. Set the RS-232 COM 1 port on the CM6800 as ASCII.
3. Set the baud rate on the CM6800 to match the baud rate on the recorder.
You can also connect to the additional ASCII ports on the CM6800 via an RS-232 to RS-422 converter. Refer to the CM6800 or
CM6800E manuals for the correct ASCII ports.
