About the Model Railroad

RTAC Software


The Randall Museum in San Francisco hosts a large HO-scale model model railroad. Created by the Golden Gate Model Railroad Club starting in 1961, the layout was donated to the Museum in 2015. Since then I have started automatizing trains running on the layout. I am also the model railroad maintainer. This blog describes various updates on the Randall project and I maintain a separate blog for all my electronics not directly related to Randall.

2016-10-08 - NCE USB Limitation

Category Randall

Simply plugging the NCE USB to Power Pro resulted in no status from AIU card whatsoever.

Consensus is that will never work on the USB (when it ironically works on a PowerCab, but only with one AIU on cab address 4).

Bottom line for Randall I'm going to have to switch to RS232 with a USB adapter.

  • All forums and sites point to the same Keyspan USA-19HS adapter:  … $25.
  • Need a Straight (not null modem) RS232 cable, 50 ft will work here.
