6.6.3 Blurry image on the remote display
[1] Content
This problem occurs due to cable loss , long cables are used in connections or ,
there is a mismatch with the input impedance on the remote display side.
Correct operation has been confirmed using a 30 m cable to connect a JRC VDR,
when using the CQD-1831 (VDR I/F kit) and a 3C-2V coaxial cable.
[2] Problem location
[2]-1 Cable type
If it is necessary to transfer signals over a long distance, use a coaxial cable (such
as 3C-2V).
[2]-2 Cable length
If it is necessary to transfer signals over a distance of 30 m or more, use a buffer
amp (sold separately) in between the main unit and the remote display.
[2]-3 Remote display
The signal quality is also affected by the monitor used for the remote display. If
the display is still distorted when a coaxial cable is used, the situation may be
improved by using a buffer amp.
