TheDave2 Posted August 30, 2011 Report Share Posted August 30, 2011 I have found that when using this module, I must check that the number I send to a channel be limited to 0-4095. If I send a number > 4095, the next higher channel output voltage is influenced. For example, channel #2 has #2048 sent to it so it puts out 5.0vdc. Then, by accident, I send a number, such as (I don't remember the exact #) 9000 to channel #1. Well, channel #2 now read 5.5volts, not 5.0vdc as it should. I do not remember what channel #1 outputted. This is not good. This should not be. I am guessing that the hardware that converts a 16 bit register to a voltage is not clearing the high order bits before conversion. Quote Link to comment Share on other sites More sharing options...
