Chapter 5 Troubleshooting
Recommended action
Set the encoder to start encoding.
Set the decoder to start decoding.
Make the correct streaming setting of this
device and the encoder by referring to the
Software User's Guide.
Refer to "Network" in this table.
If yes, confirm the followings.
- Is system bit rate exceeding connected
network capacity?
- Are FEC/ARQ settings in this device and
the opposed device correct?
- Are the network device and LAN port
settings (AUTO, Full/Half-duplex, etc) the
same?
Change encoder setting from PAL to NTSC.
(Check decoder setting too.)
Change encoder setting from NTSC to PAL.
(Check decoder setting too.)
Encoder is working normal.
If this problem improves normal when
changing ON or OFF, the input or output
signal is bigger or smaller than the
normal range.
Check this equipment connected.
Encoder is working normal.
The iris adjustment of the camera is
possibly necessary.

Check the power and operation of the
receiving device.
Check the connection between the receiving
device and speakers.
If yes, refer to the user's guide of the
receiving device.
If pulling out the cable from this equipment
eliminates the noise, audio signals may have
