Missing Video
If a DAXI with two or more auxiliary sources connected boots up normally (PWR
LED and ASI LED both ON) but the video portion of one or more channels is
missing (VIDEO LED OFF), check for one or more of the following:
 The missing service or services are not provisioned on the DSAN.
 The DAXI ASI output is either not connected to the DSAN or the ASI
interconnecting cable has excessive loss. The use of no more than 250 meters of
Belden 8281 cable or equivalent should ensure that the signal reaching the DSAN
exceeds its input sensitivity threshold.
 There is a loose video cable connection between the program source and the
DAXI. To verify a loose or defective video cable, swap the input connections at
the DAXI back panel and see if the problem goes away or moves to a new
channel. If the missing video problem remains with a particular auxiliary
channel for two or more sources and cables, there may be an internal fault in the
DAXI.
Refer the unit to your local customer support center for servicing, if needed. See
Customer Support Information (on page 23) for contact information.
