Bad DMX Widget?

We have a a dmx widget and a programming wing that had been put away and have not been used in almost a year. Last weekend they were sent out on a job and no matter what the tech tried he could not get the widget to send a dmx signal. I have reinstalled the software and drives and have even installed them on another computer and no matter what I do the only indicator light on the widget that illuminates is the "link" light but from what I understand the "TX Mode" and "DMX Ok" lights are also supposed to illuminate. The wing appears to function just fine and I have tried with the widget plugged into the wing as well as directly into the computers with the same results. To me it sounds like the widget has gone bad...opinions?
