In case it helps, I happen to have a brand new and unused Stowe Dataline S/D, c/w its two manuals, which I bought in 1993.
Stowe were taken over by Robertson and later rebranded Simrad so I suspect that what you have is just the re-branded Stowe Dataline system.
The troubleshooting section of the manual for my Stowe S/D includes:
"All repeater LCDs show bars = No information from Databox - Check wiring from Databox to Repeaters, particularly Green and White wires." followed by the cryptic alternative "Return Databox for service"!
This is the only reference in either of the manuals to "All repeater LCDs show bars".
Hope that this proves helpful...
Feel free to phone me [see PSSA Directory]if you want to quiz me about any other contents of the manuals.
sincerely
