Have you gone through the serial loopback tests etc. that are in the serial setup page in the manual?

James

Yes, I downloaded CDM 20814 setup.
That's when I got com 2 and 3.
Will not connect through TS using a new car project.
Earlier using the mini terminal in TS I got a return echo on com 3 now itis not working.

Do the responses change if you power up the MS3 with the boot jumper in place?

[Ollie8974]

I am trying to connect with MS3X.
Using the USB A-B cord.

This sounds like the issues I was having when I didn't have the ftdi drivers installed.... I could see the port but it would not comm with the MS3, would not loadfirmware...

Yes, FTDI Drivers are installed, See post #5
laptop connected to ECM with USB A-B cable.
The driver opened the com port
The Port Check 2.1
opened com 3
mini terminal in TS
echos back
The ms3loader_win32.exe can not find an open port or connected ECM
Start a new car project in TS can not find the ECM

AH...gotcha, its been a long time since I installed that. I didn't realize it came up with CDMxxxx

Is it possible to borrow another computer to rule out the computer being stupid?

[Ollie8974]

I will load it on my desk top see what happens.
Would sure like to have MS installed on the lap top for on the road tuning later on.
Loaded MS on the desk top.
Connected with USB A-B
Port Checker found and opened com5
TS mini terminal did not echo
ms3loader_win32.exe did not connect.

[Matt Cramer]

Does the desktop have a DB9 serial port? If so, try it.

[Ollie8974]

The desk top does not have a DB9 connector.

[jsmcortina]

Port Checker found and opened com5

ms3loader_win32.exe did not connect.

This is most odd - "portcheck" and the loader are almost the same code as far as serial comms are concerned.

Please run the loader again and use debug option #3, this will spew out lots of serial debugging information.
Please upload a screenshot of what it says during probing.
