At the bottom of the command line help screen dialog, it should show what command was causing problems. You should not need to do anything. Z3801A should be auto-detected. You can skip the auto-detect by editing the heather.cfg file and changing the /rxa command to /rxz Are you using a null modem cable with the Z3801A... it needs it. Also do you have the proper serial port selected? If you have a /br command setting the baud rate, that would override Heather's auto-detect trying different baud rates or the /rxz command setting 19200:7:O:1 ----------------------------- > I am trying to use Heather with a z3801. I have tried numbers of combinations of what should set the system to the Z receiver. But none seem to work. It immediately brings up the help screen and I assume that says the command is bad.

Mark Thank you for the secret on setting the receiver I was making it way to hard. The 3801 absolutely has a problem. Locks and everything just fine. Takes about 20 minutes from a cold start. It will accept commands I am not getting the correct output back. Everything had worked so it is a real problem. I used any number of programs with it. HP satstat gpscontroller and other old programs. So none of that is sick. The output is 0 to 3V approx and its a LT1180 so it should be +- 5V at least and more like 7. So somethings sick. Its on the bench and will scope it out. Thanks again for your fine work.
