Be sure that the
End of Line Jumpers
are used on the camera circuit board and in the last
monitor on each riser. If the last unit on a riser is an audio only unit, the End of Line Jumper
would still be used on the last monitor on that riser. This is important for best picture quality.
For more information refer to Page
12 - End of Line Jumper Locations.
When connecting C333-2 harness between SP333 and SNT333, ALWAYS observe 24VDC Polarity.
