So you can send a command from a computer/microcontroller into the serial input, and the Base will echo that command to the DZ-2001 connected to the Base output. So at least with Legacy, no need to make a special cable if you use the Legacy Y-cable.
Never thought about the RS232 true voltage issue, but the Legacy base hasn't fried my DZ-2001 yet! I did remove the DZ-2001 LED to reduce the load on the base.
That is not totally correct. The command base only echos commands out of its serial port that came from a CAB remote. It does not echo them if they are inputted into its serial port. However, if you have the Lionel LCS SER2, that will echo them back out to your computer even if they are inputted into its serial port.
