no video is shown on the encoder GUI video display then the encoder may not be
encoding the video and may need to be hard reset or returned to KBC for further
diagnostics. Other possibilities remain which can be further trouble-shot via KBC
technical assistance.

4.4 PTZ Control

If the camera will not respond to PTZ commands, check the following:

4.4.1 Check Serial Protocol and Wiring Format

Check the mode selection switch to ensure that it is set for the correct protocol. A
solid RX LED will appear if the switch is set for RS-232 but wired for RS-422/485.
See section 2.2.6 for the appropriate wiring schemes.

4.4.2 Ensure Matching Baud Rate

The decoder Baud Rate must match the encoder and all third party PTZ equipment.
Make sure that the camera / control system is set for 9600 BPS or set the decoder
(and encoder) for the correct Baud Rate needed.

4.5 Audio Issues

If the audio device is not producing audio, check the following:

4.5.1 Audio Input

Verify that the audio in and level are selected from the decoder Host Settings found
in its GUI. Ensure that a stereo cable is connected to the “Audio In” from an
amplified audio source.

4.5.2 Audio Output

Verify that the stereo cable is connected to the “Audio Out”. Check the encoder GUI
for the volume in selection and volume level.

4.6 Contact Closures

See section 2.2.8 for the specs of the alarm input and output parameters.

4.7 GUI Tools

Go to KBC Networks’ website to download the IP Utility tool to assist in diagnostics
of the encoder and decoder IP devices.
