c:\>ping “VideoJet IP address”
If it is reachable there will be a response like the following:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the LAN path is not functioning correctly, the ping command will time
out. In that case you could have one of the following problems:
•
Wrong physical connections: Make sure the LAN Link LED is on. For
more information on this item see the section above.
•
Wrong network configuration: Verify that the IP address is entered cor-
rectly and that subnet mask and gateway address are set properly.
Otherwise ask your network administrator.
Troubleshooting Connection Problems
If you fail to connect to a
VIP
system from either a hardware receiver
VIP -
VRx
or a
VIP -SW1
software decoder, check the following points in order to
pinpoint the problem:
•
Be sure not to connect two units of the same type, e.g. receiver to
receiver.
•
The
VIP -SW1
software decoder will refuse to connect to a
VIP - VRx
receiver.
•
Make sure network connectivity is available, e.g. by using the ’ping’
command as described above.
Troubleshooting the Video Connection
If no video or a distorted video image is displayed at the
VIP - VRx
receiver
or
VIP -SW1
during a connection to a
VIP - VTx
transmitter:
•
Make sure to use the right
VIP
unit for your application: a camera can
only be connected to a
VIP - VTx
transmitter, never to a
VIP - VRx
receiver!
•
Make sure the camera is switched on and the coaxial cable is con-
nected to the
VIP - VTx
transmitter.
•
Check the camera cable and connect a video monitor to the cam-
era in order to check that the latter is functioning correctly.
•
If a VCR is to be used as a video source and the image is distorted,
select the input source VCR in the video configuration page.
•
At the receiving system make sure the monitor is switched on and the
coaxial cable is connected to the
VIP - VRx
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, i.e. PAL or
NTSC, check the setting of the video output format in the video con-
figuration page.
