Reply to "TMCC Control With Arduino"

Don, you should get an RS232 shield (or similar) to convert the serial comms and voltages to bytes that you read/write to the shield's serial port using an Arduino lib.  Once you are comfortable reading and writing bytes to the shield, then connect it to the Command Base and watch what you receive at 9600 baud 8 bits, no stop bits.  (the cable needs Tx, Rx, and Gnd wired).  You'll receive sets of three bytes beginning with 0xFE.  Then construct and write a 3-byte set to the shield.
