Problem
Action
Live video will be cut off
• Check if the power supply system is properly connected.
• Check if coax / UTP cable is connected properly.
• Check if B-Linx / T-Linx Port LED is ON.
• Check if the network port is properly connected and the network setting is set
correctly.
• Check the system for the input voltage from the power source.
• If the problem persists even after you have taken the above actions, check the
other network device settings (e.g. IP camera, NVR, etc.)
The system does not turn on and
the power indicator on the front
panel does not work at all.
• Check if the power supply system is properly connected.
• Check the system input voltage from the power source
• If the problem persists even after you have taken the above actions, check
power cable and replace it if necessary.
B-Linx / T-Linx
port Indicator (LED) is blinking
• Check the Coax / UTP cable if it is shorted.
Join LED is not ON
• Check the Coax / UTP cable if it is connected properly
• Check UTP cable order if it is correct
(Cable order should be EIA/TIA-568B Type)
• Check if the password of the Local Node (Receiver) and
Remote Node (Transmitter) is matched.
• If the password of local node(Receiver) and remote node(Transmitter) is not
matched or unknown password is entered, please join the both devices again
Please refer to Joining configuration on '2.4.3 Joining instruction'.
No network connection
over coax / UTP
• Check that the cable length does not exceed transmission distance limitation
(e.g. 500 meters)
Please refer to Specification on '2.5 Transmission distance & Bandwidth
by distance'.
• Check the cable condition and ensure all BNC / RJ-45 connection are secure.
•
Check if there’s any kind of signal booster, noise filter, repeaters, other
amplifiers for the signal on cable, if yes, please remove them before installation
of the devices
• Check the Coax / UTP cable if it is shorted.
No network connection from
receiver to network switch or
NVR, or transmitter to camera
• Check that the cable length does not exceed transmission distance limitation
(e.g. 500 meters)
Please refer to Specification on '2.5 Transmission distance & Bandwidth
by distance'.
• Check the cable condition and ensure all BNC / RJ-45 connection are secure.
•
Check if there’s any kind of signal booster, noise filter, repeaters, other
amplifiers for the signal on cable, if yes, please remove them before installation
of the devices.
Transmitters are not turned
powered on
• Check that the cable length does not exceed transmission distance limitation
of 100 meters.
• Power the transmitter with separate power supply to check it turns on.
PoE is not enabled to end-
devices even the transmitter is
working properly
• Check that the network cable is in good condition and has been assembled
correctly
•
Confirm if the camera is IEEE802.3af/at PoE Compliant.
• Please check that the Ethernet length does not exceed transmission distance
limitation of 100 meters.
• Check the PoE output Switch on the Transmitter is set to ON.
• Due to power drops on the cable, may need extra 56V power supply on the
transmitter
