Series Default Local/Host Play Troubleshooting Screens

This section shows and defines the status screens displayed by N2x51 Series devices.

FIG. 58  

Host Play Screen

FIG. 59  

Local Play Screen

 

Displayed when Decoder....

...and Encoder....

Notes

• is set to view an Encoder stream on 

the network

• is  set  to  HostPlay,  or 
• does NOT have a valid input video 

signal

Seeing this screen means that the Decoder CAN 

communicate with the Encoder across the network. 

It is a good way to troubleshoot network 

communication between segments using only 

Encoders and Decoders (without the need for source 

video into an Encoder).

Displayed when Decoder....

Notes

• is set to LocalPlay mode

If the Decoder is NOT set to 

Local

 

Play

 mode, this screen could signify a network 

communication issue.
