Conference call with Flannery
first we established a TeamViewer connection so I could check scoreboard configuration settings on their computer.
Scoreboard was set to Daktronics Horizontal, Comm 4.
I asked user to unplug the USB serial connection to verify that comm 4 was being used for the scoreboard. Verified correct
I ran a countdown clock on the Heats race page and asked what lights were showing. She said Power, Tx CL, and RX CL were on solid.
I asked to power the scoreboard down then up (outside AC Plug)
I asked user to send pictures of wire connections in the tower. see attached pics for view of configurations discussed.
computer port terminations good
Curious as to why Computer to sig convertor was terminated on TB2 (RS 485/422 protocol) instead of TB1 (Current Loop protocol)
I asked user to open the signal convertor to see how the jumpers were set
Jumpers were on 12 to N and 13 to P which indicated that the DB9 should be pluged into J1 and the Scoreboard wiring should be pluged into TB1, not TB2
The user changed the Signal convertor termanations to TB1 and J1 we activated the scoreboard in Moscore and some of the lights turned on as they were expected to do but they were very dim, and the left hand side of the scoreboard did not turn on.
This seems to indicate that the Scoreboard lamp driver board may have some issues.
I recommended they open the scoreboard panels and check for corrosion or visible damage or call Daktronics support for a driver board replacement
User said they will look into the insoection at a later date
