Cable connection
Shut down the peripheral devices prior to connection. Connect the supplied cables from NetworKam to
the related devices according to following steps. Note that power adaptor must be kept unplugged until
other cables are firmly connected. For the first access to NetworKam without Ethernet, administrators
may use the included null modem cable to connect to COM for direct connection. It is also convenient for
administrators to access NetworKam through the null modem cable directly without modem or Ethernet
card. After necessary information is entered, a modem can be used to dial into the Internet.
Power on
Make sure all cables are correctly and firmly connected. Turn on cameras, sensors, alarm devices, and
then finally attach power adaptor of NetworKam to the electric power outlet*. Since most automatic
detections of hardware perform when the system starts, NetworKam should be turned on after all
peripherals are turned on and ready.
Connect the power jack of the power adapter to NetworKam prior to plugging the utility end into a
utility power outlet. It will reduce accidental electric surge shock.
