Command Station


Some older EasyDCC systems may need an update to their built in program. This is done by replacing the "PROM" chips in the command station with a newer version. Version 207 is known to work well, but version 022 is known to have some problems communicating with a computer. Later EasyDCC command stations will connect OK.



  1. To connect your computer to an EasyDCC system, you need to connect the Command Station to the computer's serial port using a special cable. This is not an item that computer stores generally stock, due to the special RJ11 connector needed at the command station end of the cable. You'll probably have to make this cable yourself, or have another CVP user make it for you.

    For more information on how the cable is wired, see page 134 of the EasyDCC V4 command station manual or page 143 of the V6 manual (a version in PDF is available on the web).

    One easy way to connect the system to your computer is to buy a 9-pin serial cable and a phone cable, then cut them and splice them together.
    With computers without a dedicated serial port, use a USB-to-Serial adapter.

    Alternatively, you can connect your EasyDCC command station to your computer running JMRI over a networked serial box as (see below).




Connect to a networked serial box such as the Lantronix EDS8PR/16PR/32PR as a virtualized EasyDCC over Serial connection in JMRI, as demonstrated by david zuhn.


To complete the configuration, restart JMRI. You should now be up and running.
Notice the EasyDCC menu on the main JMRI screen.
