One of our TIMYs developed a bad Channel 0. The timer would only receive pulses on a random basis from the banana plug inputs. It was exchanged for the TIMY being used for Cyclestart where the pulse is being sent out the Channel 0 to open the start gates for cycling. The DB25 is connected to the control relay and works fine. The output from the banana plug jacks worked for 30 minutes than died. Plugging in a jumper into pin 1 on the DIN connector has been solid so far. A trip back to Austria will no doubt reveal the issue. It is nice to know that there are two other ways to get signals in and out of the TIMY. Saved us today at the US Team Cycling trials at the Home Depot Center in LA.
