I have a Legacy system with a ZW-L. Recently the engines on the D throttle started running in the manual mode where I was only able to control them by the throttle on the ZW-L {the D handle.} I feel that this was an odd problem since one throttle on the ZW-L {the A Throttle still was able to control my engines through the Legacy remote.} I tried to reset the system and it was not fixing the problem. This problem persisted for a few weeks, I did not have time to investigate the issue. Then the A throttle on the ZW started to do the same, none of the engines would run under the Legacy remote, A or D throttle. I could only control them through the handles on the ZW-L. Does anyone have a suggestion as to what I may do to reset or fix the issue?
