CONNECTING LOOPING VIDEO
The NET5308T-EXP supports looping video. It passes the video input to a monitor or other analog video device.
To use looping video:
1. Connect a coaxial cable to the video out connector on the rear panel.
NOTE: You may have to use a BNC installation tool to connect coaxial cables to the rear panel.
2. Connect the other end of the coaxial cable to the analog device.
3. After installation, use the Endura workstation to disable video termination for the video channel.
4. If looping video to additional devices, disable video termination (Hi-Z) on each device. Enable termination (75 ohms) on the last device.
NOTES:
•
•
If you do not terminate the video signal at the last device in the series, ghosting or other imperfections may appear in the video signal.
•
During a power loss, the video termination settings may be lost. As a result, video imperfections may appear on devices that receive
looping video from the NET5308T-EXP. If this is not acceptable in your installation, use alternate looping methods.

1. Make sure your audio input device matches the 1 Vp-p line input level (+4dB, 1.228 V maximum). If the audio source does not match this
specification, audio distortion problems may occur.
2. Wire the audio input device to the 3.5 mm monaural audio plug as follows:
3. Insert the audio plug into the audio connector for the video channel on the NET5308T-EXP rear panel.
