Tom,

- You would use a Turnout in JMRI to control the track power of the PSXX via JMRI. The default would be the system address T2042 (when you click Add... in the turnout table, this is what you type in), which ends up with the turnout MTT2042

- The PSXX manual () on page 13 details the mechanism by which to change the turnout number that turns off a specific PSXX.

- If you have a UWT-100 or UWT-50, you can turn the power on/off by pressing the switch button, entering the number (2 0 4 2) then using the On or Off soft buttons (two / three dots) under the screen to turn the track power on or off. If you created the JMRI Turnout entry, that will follow your selection on the throttle.

cheers

Dwight,

The issue is that I have multiple PSX connected to each booster. You can program an address on a PSX to turn track power on or off.?

The booster output controls the PSXX's track power. Turn booster's track power off and the PSXX also turns off.

CV66 determines how the PSXX powers the track when the booster turns on:

• CV66 = 0: Power stays OFF at startup. Useful for inactive areas (e.g., staging yards). Power must be turned ON via an accessory command

• CV66 = 1 (default): Power is always ON after startup

• CV66 = 2: Power resumes its previous state (ON or OFF) from the last shutdown

There is no CV to control what the PSXX does when track power turns off.
