Troubleshooting Connection Problems
If you fail to connect to a system from a hardware receiver, check the following to pinpoint the problem:
•Do not connect two units of the same type (for example, receiver to receiver).
•Make sure network connectivity is available (for example, by using the ping command as described above).
Troubleshooting The Video Connection
If no video or a distorted video image is displayed at the receiver during a connection to a transmitter:
•Make sure to use the right unit for your application: a camera can only be connected to a transmitter, never to a receiver.
•Make sure the camera is switched on and the coaxial cable is connected to the transmitter.
•Check the camera cable and connect a video monitor to the camera to check that the camera is func- tioning correctly.
•If you will be using a VCR as a video source and the image is distorted, select VCR as the input source in the Video Settings Configuration Page.
•At the receiving system, make sure the monitor is switched on and the coaxial cable is connected to the receiver.
•Check the monitor cable and the selection of the monitor channel, if the monitor features more than one video channel.
•If the monitor can display only a single video standard (PAL or NTSC), check the setting of the video output format in the Video Settings Configuration Page.
Testing The Audio Connection
This test procedure applies only to units with the audio option.
Test Between
1.Connect a microphone (via a preamplifier) to the
2.Make sure the correct menu items are set in the Audio Settings Configuration Pages of both systems; that is, select the appropriate interface (line I/O or handset).
3.Switch the coding mode to G.711 or G.728.
4.Select a volume above zero.
5.After establishing the Ethernet connection, audio should be transmitted both ways.
6.Be sure the level is not set too low and that the right interface is selected.
7.If you cannot hear any audio, check the microphone and loudspeaker together with other audio equipment, and make sure the microphone is switched on if it has a power switch.
