So after playing around with mt Arduino Uno and associated IDE this weekend building a super "Blink" program and re-learning C syntax I'm ready for more challenges. Want to blow the horn on one of my TMCC engines. Thanks for the code samples, so I have a head start. All the other TMCC modules use only the Tx and Gnd wires from the base daisy-chained to Rx and Gnd on each control module, except the Action Recorder which sends its Tx line back to the TMCC base Rx pin. I don't have an Action Recorder so can't I just connect the Tx and Gnd from an extra RS-232port on my Arduino Mega to the Rx and Gnd on the TMCC base unit. Do I even need to connect the Tx from the base to Rx on the Mega? That would just add on to the current Rx daisy chain. I have extra 3-wire RS-232 TMCC cables, can't I just connect one to the Mega and use one out of the TMCC base and cross-connect them appropriately? Let me know if I have this close to being correct. Sounds deceptively too easy. What baud rate do I need to assign? Thanks again for helping.
