One is as simple as I can make it and works well with either the SX28 or SX48 module using the SX-Key and Debug/Poll combination. The other is your (JM) PING.SXB. It runs perfectly well using the SX28/Debug/Poll combination. However, when an SX48 module is placed in the PDP's 40 pin socket (and the SX28 removed, of course) and the Device is changed to SX48 along with the necessary movement of the output pin from the SX28 socket's "RB.1" to the 40 pin socket's "1", it will not execute using the SX-Key and Debug/Poll combination. I have no ego and fully expect that I am doing something so dumb as to be a waste of your time. I may have a flaky SX-Key. (I only have one.) I have tried several SX48 modules with the same results. (I have a bunch.) I appreciate your help! --Bill ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=415372#m415559 Need assistance?
