Hello all. I am relatively new to JMRI. I have used it to program locomotive decoders and am now looking to install and program signals at a quad interlocking.

Hardware: Digitrax DB150 command station, Digitrax PR4 decoder programmer, Digitrax SE8C decoder, and an Azatrax MDR6 for sensors. Windows 10 laptop.

I've installed JMRI Decoder Pro and Panel Pro. Having connected all the hardware, I've been able to power on the test signal and change signal indications using the control panel in PanelPro under the example configuration provided by the JMRI install (PanelProTest). However, when I attempt to create my own panel I do not get any communication between the PR4 and SE8C. It seems there's limited information online about how to set everything up in JMRI.

From what I've read and tested I suspect in creating a new panel, I first have to add the SE8C to PanelPro. I do not see the SE8C listed under LocoNet as I did in the example configuration. When I'm logged into PanelPro using PanelProTest, under LocoNet I can see an option to configure the SE8C.??

I am unsure of how to add the SE8C to my own active configuration profile.Can anyone point me to a manual or something to reference on how to accomplish this first step?
Once I get past this step, I am assuming the next step would be to create a panel, then create signal heads, then signal masts, which would then be added to the panel.

The signals I am installing are 2 target type-G signal. I will have 3 sensors in the track, and will be adding a wabbit to tie the switch position in to the SE8C at a later date.

Any help is appreciated!

For the problem where JMRI is unable to communicate with the SE8c:

See for information on the ways in which the PR4 can be used with JMRI.

You probably have used JMRI with the PR4 as a "standalone programmer", where the decoder is on a programming track which is connected to the PR4. This is the first usage mode in the first table shown in the web page mentioned above. In that mode, the PR4 does not communicate with LocoNet.

For communication with the SE8C, the second mode in the first table is the one you want.

Most users will implement one "configuration profile" configured to communicate with the PR4 in "standalone programmer" mode, and one configuration profile to communicate with the PR4 in "LocoNet interface" mode. When you have two (or more) separate configuration profiles, JMRI will start-up with a chooser window so that you can select one of the profiles (or it will default to the last-used profile if you don't select one within 10 seconds).

Note that JMRI can be used for programming decoders via the command station's programming track connections when used with a PR4 "LocoNet interface" connection. But because you have a DB150, you would be limited to write operations using that mechanism, since the DB150 does not support CV reads on its programming track.

As such, with the configuration shown above, it is appropriate to switch to the "PR4 standalone programmer" profile for programming, and switch to the "PR4 LocoNet Interface" profile for signaling development and operation.
