3. Blinky Box feeds more current into the line than when Disabled This safety factor guarantees that if the line looks OK when Disabled it will work correctly when enabled It s possible to get an output trigger when Enabled even if the Input LED won t light when Disabled What this means is that the Blinky is reading the gate switch but the line resistance is too high for reliable operation And if correct operation can t be guaranteed the line shouldn t be used Copyright 2006 2008 The TimingGuys Inc All rights reserved Reproduction without permission is prohibited 9 Ver 1 9 Technical Notes Copyright 2006 2008 The TimingGuys Inc All rights reserved Reproduction without permission is prohibited 10 Ver 1 9
