    I haven't logged into Discord for a long time, and I can't join DCC++EX's channel. So I take the liberty of asking my question.
    I use the EX Station monitoring command <D ACK ON><R>to read the CV values of the locomotives in the programmed track. The callback value is always-1.
    Similarly, I use JRMI to connect EX Station (using DCC++), read the locomotive CV value in the programming track, can get the value and take ACK discharge action is normal.
    I feel that the JMRI and ACK limit current is different from the ACK limit current of the EX Station monitor. Is this the case? How to adjust?

    https://dcc-ex.com/reference/tools/diagnostic-d-ack-command.html
    Code:
    <D ACK LIMIT 50>
    <D ACK MIN 2000>
    <D ACK MAX 20000>
    The default values were updated in version 4.0.2
    ACK defaults set to 50mA LIMIT, 2000uS MIN, 20000uS MAX

    Previous values were 60mA, 4000uS, 8500uS

    To add your preferences in DCC-EX

    Commands can also be sent from JMRI.
    JMRI Menu items:
    DCC++ >> Send DCC++ Command
    DCC++ >> DCC++ Traffic Monitor -- and use the 'Show Raw Data' checkbox

    Thank ash,Problem solved. It's my engine contacts that are not making good contact, not EXCS.
