I guess I missed something in the flurry of messages, but I thought you wer= e now using a switcher so the input voltage above 5.5V is not a problem, in fact desirable. Certainly a switcher can be set to deliver pretty close to 5V out, so what's 5.5V got to do with anything now? ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
