Thank you @Fausto Ok ... That makes sense about the adjacent channels floating and picking up signals. That was my second guess on what was going on with this unit. What is the command for disabling a channel dynamically? Does disabling a channel remove the channel from the list and will I have to then handle the array to accommodate the removal (disable of the channel)? Would using the module in differential mode eliminate the channel float? Is there a way to tell if a sensor is disconnected and then program something to dynamically disable the channel or set an alarm? Besides the fact that I was getting readings that don't make any sense. I have to come up with a solution for the event where we have a sensor failure or broken wire during testing. How will I know when or if this happens and whether or not the data I am getting is still valid? Juan

I am reading channels on a USB-1608g it appears to be ok when i have all of the channels plugged into sensors but when i unplug some of the sensors it looks like i start getting repeated data in the channels that were unplugged. I am wondering what happens to the data map in the device when the sensors are disconnected? does the device shrink the array of data so that when i am reading data i am not reading data out of order and perhaps overflowing because i am trying to read more data than active channels? I'm trying to debug this remotely so i can't run the VB and watch the variable arrays coming back. Juan
