Error when uploading sound file to engine

Chris,
I have received this error in the past when the Loader software can't find the TIU's serial port. Sometimes unplugging and reconnecting my USB to serial adapter will refresh the COM port and then I use the command "Options>Serial Port>Auto Search for TIU". Not sure if this will help in your case as you may have already tried this.

This error is not the same as not finding TIU.  It has TIU on Comm 4.  It is engine related.  I would make sure red to center rail and black to outside if your talking PS-2.  Does engine work fine otherwise?

Sometimes you just need to power down and start over.  Going slow between steps, especially after applying power to engine.  G

The TIU is on Comm 4 so that's not the issue.   I have it connected to the laptop via a USB cable.    The engine I was trying to change the sound file on is a brand new PS-3 engine. 

PS/3 are sometimes a little more tricky to get a good sound file load.  A couple of things to try.

• Do the load on a piece of test track, not on your layout.
• Power the TIU channel with DC, 14 to 18 volts.
• Provide a 20-30 foot wire between the TIU and the test track.

That's the configuration that MTH used when I went to the ASC training, and it's how I load them here.

The TIU didn't see the engine. Before trying to change the sound file, maybe try to run the engine as G points out.

I was able to start the engine  & access all the functions , so the TIU sees it. 

Christopher,

Do as Gunrunner John suggests.  The 20-30 feet of cable is to be coiled.

Also, on the loader - go to options -  serial port - try and auto search for the TIU.

Using DC power is highly recommended, it provides a cleaner signal.  You are dealing with digital signals.

I had this same message popping up over and over as the download was moving like molasses on a winter day. What worked for me was moving my wires on the TIU from Fixed 1 to Fixed 2. The download went super fast with no messages after doing this.

Similar to what Dave just posted, I was trying to upload a file to a PS3 engine with two different original REV. G TIUs and it was extremely slow. Then I tried my REV. L and the upload went quickly and smoothly.

There are some post on this. Those original Rev G can have issues with PS-3, especially sound file loading.  G
