3 Trouble shootings
1. Why can’t log on the equipment via the NMS?
If you’re sure the cable connection is firm, you can make the following check:
■
Network blocking
Check network and make sure the network transmits fluently, and the checking
is conducted at set intervals by the software, so the possibility can not be ruled
out if a disconnection occurs.
■
IP address conflict or setting error.
Check IP address, and there is a default address as the device dispatched.
Please modify it according to the actual IP address at its debut, and for easy
management, do not randomly change the address once it was set up, because
the correct IP address is directly related to the network management.
2. Why is there not output stream while the input signal is good?
If you’re sure the monitor and equipment receiving the signal from encoder are
working normally, Please check:
■
Does the resolution of input signal match with the selected input source?

Is the bit rate overflowed or set too low?
Please check the video/ audio bit rate and adjust them to an adaptable range.
■ Is there any
conflicts with the PID in other TS stream?
Check the Video/ Audio/ PCR/ PMT PID, and modify their PID and distribute
different PID to them.
3. Why does the picture pause or is the picture color abnormal?
■
The program format (PAL/ NTSC) of the decoder and the input source o are
