Focal 914-HDE User Manual page 48

5. Video Issues:
a. Does the GUI report video on both ends?
b. Is the Optical link working?
c. Verify power status of both ends of the system.
d. Are the firmware revisions of the cards compatible? Refer to Section 8.1.
e. Are the card versions compatible? M1 to M1? L1 to L1?
f. If no video is present at the remote side:
i.
ii.
iii.
iv.
v.
g. If video is present at the remote, but not at the console:
i.
ii.
h. If video is present at both ends of the system, but not displayed:
i.
i. 3G-SDI video should only be used in M1 version with no 914-VDX cards and Ethernet limited
to 100 Mb/s.
6. 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.
ii.
iii.
c. Ethernet channels are linked, but frames are dropped:
i.
ii.
iii.
d. Are the firmware revisions of the cards compatible? Refer to Section 8.1.
e. Are the card versions compatible? M1 to M1? L1 to L1?
7. Serial Port Issues
a. Is the correct protocol configured for the channel in question? On both ends of the system?
b. Is the correct half of the connector sued for each channel: the lower row is the first channel,
the upper row is the second channel.
c. For non-isolated ports: is the equipment connected powered from the same ground reference
as the 914-HDE stack?
d. Tx is output from the 914, Rx is received (input) to the 914. Are these crossed?
e. For RS485/422: Is the +/- polarity swapped?
f. For RS485: Is the timeout configured for the port appropriate for the baud rate of the attached
equipment? Slower data rates typically require longer timeouts. The timeouts represent the
turnaround time of the half duplex protocol to change from Rx to Tx and vice-versa.
g. Is differential termination required for RS422/485? This can be enabled and disabled via the
GUI. In a multi-drop RS485 network, only the final node requires termination. The 914-HDE
serial ports default to enabling the termination, this must be disabled if termination already
exists in the system.

Check cabling at the remote side.
Verify power status.
Ensure composite video is plugged to the 914-VDX card.
Ensure SDI video is plugged into the 914-HDE card.
Ensure the cards are configured for video input at the remote via the 914 Diagnostic
GUI.
Verify that the optical link is valid.
Verify video channel is configured for video output at the console via the 914 Diagnostic
GUI.
Ensure video monitors are on and compatible with the video input.
Verify the auto-negotiate settings of each end, ensure they match the connected
equipment.
The ports are auto-MDI/X. Ensure proper cabling and pinout.
Ensure cabling is no longer than 100m
Check connection status in GUI, are both ends linked at the same speed? If not, force
the links to be the same speed.
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 6.0.
Is 3G-SDI video passing through the system? This leaves limited bandwidth available
for all other signals in the M1 version. No 914-VDX cards may be stacked on the M1
version of the 914-HDE when 3G-SDI video is required.
