I am looking to 'automate' my Christmas Post War trains this year. I plan on using a TPC 300, 135w powerhouse and an Arduino/Raspberry Pi as the controller. I think I have it figured out sending commands, except for how to set the TR number of the TPC unit for the first time. I know I set the switch to program and send it 'something' over the serial line. All the TMCC commands use the TR address as the second byte, but since none has been set, not sure how to address the TPC unit to set it. I am not using the remote so I need the binary/hex string used to address the TPC 300 for the first time. ( i.e. 0xFE, 0x11, 0x2b ).
Thanks in Advance
