DCS loader can't find TIU

Do you have all the proper cables connected for the update?

(sterio jumper cable in place?)

Do you see a light in the TIU?

Rick,

Red LED on in TIU. Stereo jumper cable inserted from proto dispatch to proto cast.

You must do the following in the following order:

• Remove all power from the TIU - Aux. Power port, USB Pport and Fixed #1 Input
• Connect the 1/8" stereo jumper cable between ProtoDispatch and ProtoCast
• Power on the TIU from either Aux.Power port, USB port or Fixed Input #1
• The TIU's red LED should come come on steady without any blinking. If it doesn't come on steady you didn't follow the above procedure and the TIU upgrade will fail.
• Click on the TIU upgrade icon at the top of the Loader Program's window and then click OK.

When you do the remote upgrade:

• Remove all power from the TIU - Aux. Power port, USB Pport and Fixed #1 Input
• Remove the 1/8" stereo jumper cable between ProtoDispatch and ProtoCast
• Power on the TIU from either Aux.Power port, USB port or Fixed Input #1
• The TIU's red LED should blink the correct number of tiomnes before coming on steady. If it doesn't blink before coming on on steady the remote upgrade will fail.
• Click on the remote upgrade icon at the top of the Loader Program's window and then click OK.

Success with one caveat. I had to upgrade because I bought my first Proto 3 locomotive. I went to the MTH site and downloaded the latest versions of the loader and updater. (tiu6p00.dcst and remote6p00.dcsr) No matter what  I did I got the COM3 error. On a whim I found  copies of  the previous versions (tiu5p0.DCst and remote5p0.DCsr) and they both installed without a hitch. Tested my trains and DCS5 show on the remote and so far so good.

So my question is my TIU to old to accept 6.0 or did I need to have 5.0 installed first?

Thanks,

Rick

You can install any version over another version, all TIU's should accept the latest version.  I've loaded 6.0 onto an old Rev. G, the first TIU version, works fine.

Maybe a bad download of 6 then?

or something happened on the computer?

OK, I was finally able to get the com to the TIU for the update of TIU itself.  That requires the stereo mini audio cable.  Looks like that is to be removed to update the remote.  all other connections remain.

I have not been able to get a serial COM connection to update the remote.  I have tried 2 different usb to serial adapters, ensured current drivers.  Recycled power on the TIU.

I have used these adapters for instrumentation work over the last 15 years.  I bought new ones also for this.  3 uSB to serial tried.  2 brands.
LED flashes about 9 times.  Not sure what is the right number, but comes on steady.  that seems to be the major difference between power up with out and with the audio cable.  

have a windows 7 notebook and windows 10 notebook.  both behave the same, which is not much because the system can't find the com.

Connections Remote in from remote - a 4 wire straight through handset cord

USB to serial (RS232 null modem?) to computer

Aux power from a Z1000

No other connections

If the TIU’s red LED flashes more than 5 times, the TIU is defective.
