Using PSX-AR auto reverser with Digitrax

[JRP]

I need to adjust the trip current on my PSX-AR circuit board in order for my locomotives to make the complete (reverse) loop without stopping. The instructions (using the Digitrax DT-400) say that after disconnecting the PSX-AR board from my system and moving the jumper to the "Program Position", I must turn the power on "PWR"+ "Y+". What do they mean Y+?? I don't have the DT-400, but have instead the DCS-50 Zephyr system. Is there something I need to know here or do different? I do not want to blow that new PSX board. Thanks.

It just means turn on the the track power,  The Z has a button to do that.
