5. General Configuration Issues
– Configurations not being saved
a. Diagnostic connection must be to the 914-HDE Console unit only. Do not connect directly to the 914-
HDE remote card.
b. Ensure that each card is correctly configured for Console vs Remote before attempting to configure
other settings.
c. A stable optical link must be present to configure remote cards.
d. A stable expansion link must be present to configure expansion cards.
6. Video Issues:
a. Does the GUI report video on both ends?
b. Are the video cards configured properly for remote vs console, and is the video input vs output direction
configured. This information can be found via the GUI.
c. Is the Optical link working?
d. Verify power status of both ends of the system.
e. Are the firmware revisions of the cards compatible? Refer to Section 0.
f.
Are the card versions compatible? M1 to M1? L1 to L1?
g. If no video is present at the remote side:
i.
Check cabling at the remote side.
ii.
Verify power status.
iii.
Ensure composite video is plugged to the 914-VDX card.
iv.
Ensure SDI video is plugged into the 914-HDE card.
v.
Ensure the cards are configured for video input at the remote via the 914 Diagnostic GUI.
h. If video is present at the remote, but not at the console:
i.
Verify that the optical link is valid.
ii.
Verify video channel is configured for video output at the console via the 914 Diagnostic GUI.
i.
If video is present at both ends of the system, but not displayed:
i.
Ensure video monitors are on and compatible with the video input.
ii.
3G-SDI video should only be used in M1 version with no 914-VDX or 914-EX cards and
Ethernet limited to 100 Mb/s.
7. Ethernet Issues:
a. Ethernet issues often are attributed to negotiation settings mismatches.
b. Are both ends of the system linked? Verify this in the GUI. If not linked:
i.
Verify the auto-negotiate settings of each end, ensure they match the connected equipment.
ii.
The ports are auto-MDI/X. Ensure proper cabling and pinout.
iii.
Ensure cabling is no longer than 100m
c. Ethernet channels are linked, but frames are dropped:
i.
Check connection status in GUI, are both ends linked at the same speed? If not, force the links
to be the same speed.
ii.
Is the GUI reporting dropped frames? If so, too much bandwidth is required by your system.
The cards can have their versions upgraded from L1 to M1, or M1 to H1. Verify required
bandwidth using guidelines from Section 3.3.
iii.
Is 3G-SDI video passing through the system? This leaves limited bandwidth available for all
other signals in the M1 version. No 914-VDX or 914-EX cards may be stacked on the M1
version of the 914-HDE when 3G-SDI video is required.
d. Are the firmware revisions of the cards compatible? Refer to Section 0.
e. Are the card versions compatible? M1 to M1? L1 to L1?
