Have you seen the section on the "hot plugging" Basically you don't want to plug the adapter into the DSATX while the DSATX has power. You should pull the fuse, or disconnect the VIN terminal, then do all your plugging, then connect power to the DSATX. The serial adapters steal power from the DSATX and the inrush of connecting them while the DSATX has power will cause the DSATX to reset or go into a bad state. There are USB adapters from FTDI that don't have this problem that I'd recommend.
