Well thats valid TTL so OK (as long as the 7I33 inputs are jumpered for TTL in) So the next step in tracing it is is to see if the GPIO for Z bit is visible in halmeter when you do the same test with a 1024 line encoder you will likely miss the index with HALScope on the GPIO bit above 60 RPM, so a real scope would really help in case you are losing the signal above a certain speed Peter Wallace ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
