Pelco VMX300 installation manual CM6700 Switcher, Connect Ground on ONE END only

CM6700 SWITCHER

To connect a CM6700 switcher directly to the VMX300(-E), complete the following steps:

1.Using a modified null modem cable (user-supplied), plug one end into the DB9 COM 1 port on the VMX300(-E). The modified null modem cable should be cut at one end, so that you can connect the wires directly to the CM6700 screw terminals.

2.Connect the other end of the cable to the COM 2 screw terminal connector on the CM6700 switcher. Note the pin assignments on the wiring.

3.Remove the cover from the CM6700 and set the SW5 DIP switch to RS-232 mode. Replace the cover when done.

NOTE: TO PROPERLY SHIELD DATA CABLE

CONNECT GROUND ON ONE END ONLY.
