I am having problems going from a Basic Stamp 2 to a Basic Stamp 2pe MoBo.· I have an RS-232 interface to a linear actuator made by Zaber that I breadboarded that works just fine with the Basic Stamp 2 on a professional development board.· The RS-232 transmits and receives fine with the actuator.· When I attach it to the MoBo, with all the pins redesignated properly, I get a great RS232 output (-10 to +8.2V) output to the actuator, but it doesn't pick up the signal.· I have checked the grounding, and it seems fine.· Any tricks?
