5. Troubleshooting
5-1. Hardware
Problem
Action
. 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)
. 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.
. Check that the cable length does not exceed transmission distance limitation
(e.g 500 meters) (Please refer to Specification on Page 13~14)
. 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.
. 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.
. Live video will be cut off
. 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.
. The system does not turn on
and the power indicator on
the front panel does not work at all.
. Check the Coax / UTP cable if it is shorted.. B-Linx / T-Linx
port Indicator (LED) is blinking
. 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 Page 11 and 26)
. Join LED is not ON
. 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 Page 13~14)
. 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.
. No network connection
from receiver to network switch
or NVR, or transmitter to camera.
. Transmitters are
not turned powered on
. PoE is not enabled
to end-devices even
the transmitter is working properly
