To enhance the power of the anti-lighting effect
，
we can consider the input front-end to join
in the power supply arrester, so that power can be greatly enhanced the ability of
anti-lightning strike. To enhance the power of the anti-lightning effect
For the device itself by the user interface to connect to the outdoor outlet signals, such as
telephone lines, E1/T1 lines, in order to achieve better anti-lightning effect, users may wish to
consider the input of additional signal lines dedicated lightning devices
And need to note that electromagnetic interference, with particular attention to
anti-static. when the observation or the transfer of the demolition of the circuit board, please
contact the circuit board by hand the outer edges to avoid touching the circuit board by hand
directly to components.
3.2 setup step
At frist please install device and fixed , and then connect the power cord, turn the power
switch, observation equipment, lights are normal. To normal, to connect serial cable, network
cable, and configure the operating parameters. Configuration is completed, connecting E1 lines.
E1 line to connect when you should pay attention to the corresponding synchronous receive light,
if the red light, try to connect the TX and RX pairs of words, the red light does not shine can be.
3.3 Notes
A. Ground must have good grounding resistance should be less than 5 ohms, preferably less
than 0.5 ohms.
B. Docking cable, the interface card bits to be solid, appropriate driving force can not fall.
C.Pull line, pay attention to circlip, must not use brute force, may cause damage to cable
connectors.
D. Don’t connect PSTN line to FXS port, otherwise will cause the FXS module damage

Basic configure
NC-AD300E can be configured by two means.
1.Through the console port to connect terminal or PC running terminal emulation software.
