Larry,

Since you have experience using the Javelin, have you tried hooking that up and getting it to work?  You're dealing with three unknown variables, the emic, the SX and Basic/asm.  Whenever I get some new gizmo, I tend to get it to work on my PC first, and then move it to an embedded processor.  If you're familiar with the Javelin, then use it to first learn about the emic and then take that knowledge and apply it to the SX.

Also, I noticed that the emic has a TTL serial input.  Do you have the polarity of the serial communication correct?  TTL to RS-232 level converters are also inverters.

Thanks,
PeterM
