Verify Bidirectional Mode Fiber Path - Duplex Only
With Simplex hardware or when Duplex hardware is in Unidirectional Mode, only one LED operates, either the transceiver’s
TX LED or RX LED. In Unidirectional Mode, the operational LED illuminates on the side of the transceiver where data enters
or leaves the hardware and indicates the individual port where the fiber optic cable should be attached during cabling.
If you are unsure of data being passed over fiber:
Yellow LED: fast blink = unencrypted video present, slow blink = free-run video present, solid = HDCP video present
NOTE:
Free run video is a video mode internal to the DXLink system. When free run video is indicated, video is not
displayed (nor is black video present) out the endpoint RX unit. This identifies a good connection with video flow
between endpoints.
Green LED: solid = full bidirectional link established
Green LED: off = link not established
Green LED: blinking = Data Link-lost Mode (no Ethernet, RS-232, IR, or USB). If Bidirectional Mode is required, check
return fiber path for proper connections and make sure DIP switch Toggle #4 is OFF.
NOTE:
When a DXLink Fiber Duplex cable run in Bidirectional Mode has one or both of the fiber optic cables on the
return path removed, the system automatically drops into Data Link-lost Mode. In Data Link-lost Mode, video and
audio continue to flow from source to destination, but network and control no longer transmit over the fiber optic
path.
Verify Unidirectional Mode Fiber Path
If you are unsure whether or not audio and video is being passed over fiber:
Illuminated LED: solid = available for use; not sending audio and video (never present: Ethernet, RS-232, IR, or USB)
Illuminated LED: blinking = receiving or transmitting audio and video (never present: Ethernet, RS-232, IR, or USB)
Verify Auto-setup Mode
If you are unsure if an endpoint has connected to the integrated Master with auto-setup, it may be because the endpoint
is connected via the wrong network.
From NetLinx Studio/OnLine Tree, right-click the endpoint and select Show Device Properties from the list of available
choices. Auto-setup endpoints’ IP addresses reside in the 198.18.x.x space where the first "x" represents either 130 (input
side) or 134 (output side) and the second "x" represents an individual port number. Non-auto-setup endpoints’ IP
addresses reside outside the 198.18.x.x space.
If you are sure that an endpoint has not connected to the integrated Master via auto-setup:
It may be because the connection (board and/or endpoint) is in Unidirectional Mode or in Data Link-lost Mode.
Restore the connection to Bidirectional Mode and reboot the input or output board.
