DigiMux
Appendices 145
Reason2: The disk (HDD) in the unit is damaged.
Solution: Contact a qualified service person to replace the disk (HDD) in the
unit. This disk should have the DigiMux software properly installed.
Reason3: The DigiMux is configured to use DHCP to obtain the IP address, but
the server is not available, there is a network failure, or the Ethernet
cable is not properly connected.
Solution: Check the DHCP server for availability, and then check the integrity
of the network. Check the Ethernet cable and either reconnect it if the
cable is in good condition, or replace the cable if it is damaged.
Monitor and Display
Symptom: The main monitor display is not clear, or the OSD is jittery.
Reason: If the color burst separation circuit of the monitor is not good enough,
the high frequency component of video signal could interfere with
the color signal, causing the display to be jittery.
Solution: 1. Use a monitor with S-VHS input.
2. Use a higher quality monitor.
Symptom: Main monitor image too bright.
Reason: “Brightness” value is too high in “Monitor Setup” menu.
Solution: Adjust the brightness to a lower value.
Reason 2: The camera iris is not adjusted properly.
Solution: Adjust camera iris to a smaller value.
Reason 3: The camera video output signal does not comply with the standard
(RS170/A).
Solution: Use a camera that outputs correct video.
Reason 4: The termination resistor is not enabled (OFF) (and the loop back
connector is not used).
Solution: Enter the Camera menu and enable the termination resistor (see
Configuration Table on page 44 for the termination resistor setting for a
camera channel).
Reason 5: The DigiMux is broken.
Solution: Contact a qualified service person.
