Troubleshooting
After completing installation, if the units are not operating properly, check each step at each unit in order.
1) If the Power LED is off verify the unit’s power connections and verify that the power source is on an active
circuit.
2) If the link status LED does not stop blinking, verify that the coax cable has been properly installed and make
sure the receiver’s link Type LED is “OFF” and that the transmitter’s link Type LED is “ON”.
3) If the Activity LED is “OFF” verify you have power to the camera and good connections to the RJ45 connectors.
4) If the activity LED is “ON” and the link status LED is “ON” and there is no picture, verify camera IP address and
monitoring IP address are proper and refresh the monitor. Directly attach the camera through a short patch cable
directly to NVR/IP network. Verify that camera and monitor programs are properly functioning.
Install Network to VR448COAX and IP Cameras
1) Connect an earth ground to each unit before making any additional connections.
2) Connect a network cable from the receiver to the security room or IP network equipment.
3) Connect a coaxial cable between the transmitter and the receiver.
4) Connect a network cable from the transmitter’s four Ethernet jack to the IP cameras or other network devices.
5) Connect the Class 2 power transformer to the push in power connector of the VR448COAX receiver. The unit
requires 24VAC or VDC @ 1 Amp. There is no polarity to these terminals.
6) Connect the 48VDC 1A power supply to the power connector of the VR448COAX transmitter.
.
Normal Operation
When power is applied to both units the Network LED’s will come on and the link status LED will blink for about 30
seconds as the link is being optimized. When the link is stable the link status LED will remain “ON”. The Ethernet data
LED will blink with network activity.
