CM6800 CONTROL CONNECTIONS
There are two ways you can connect a CM6800 to a VMX200.
ᕡ Connect a null modem cable from VMX200 COM 1 or COM 2 to the CM6800 COM 1 port.
ᕢ Connect a DB9 cable from VMX200 COM 1 or COM 2 to the CM6800 ASCII Ports 2, 7, or 8. You must use a wall block to
convert the DB9 connector to an RJ-45 connector.
Figure 9. CM6800 Control Connections
Although a CM6800-48X8 is pictured above, you can use a CM6800-32X6 as long as the COM port number of the port
connection is the same. (COM ports 7 and 8 are not available on the CM6800-32X6.)
If you connect to ports 7 or 8, you must set the port for ASCII RS-232 using the CM6800 programming menus or manager
program.
After you make the connections, open the Device Configuration window in the VMX200 software and add the CM6800 to your
system. Refer to the VMX200 Software Installation/Operation Manual for detailed instructions on system configuration.
The CM6800 settings must match the VMX200 COM port settings. Refer to the CM6800 Installation/Operation Manual for
instructions on setting baud rate, parity, and other settings.
