Xport Issues

**LFPerf** · 02-24-2008, 02:45 PM

Ive used Xport in the past with great results, due to a laptop bios failure I had to start all over with a different machine. I went to set up xport yesterday for use with iguidance and roadrunner. After a few minutes of running (working fine) either a error comes up saying an error has occurd and xport needs to shut down, or xport just shuts down with no warning. I've removed and reset it up a few times with the same outcome, any ideas?

Wow. I wonder how many people got that last one? Download the new version. Sorry.

Hi Curiosity,

I have used XPort for already a year to split GPS-Port, what was working fine.
Now I bought a GPS/TMC-Mouse (Navilock 409TE) and I'm trying to get TMC-Signal into the navigation software. This doesn't really work. I managed to get TMC connected with the XPort verision 1.19, but GPS-Signal was very unstable, appearing and disappearing every 20 Seconds or so and apparently a BSOD. With the 1.20 I get GPS connected, but TMC on the other port cannot be initialized. Do I do something wrong or is XPort not designed to handle TMC-Data?

I've never seen TMC data so I can't really give you an answer.

**Spacelord** · 02-28-2008, 02:04 PM

would it help to send you the actual GPS log?

**Curiosity** · 02-28-2008, 02:22 PM

Yes, I think that may help. Also, what do you mean by the "other" port? Is there more than one COM port and how do you initialize it?

I'll grab it tonight and attach. *done*
afaik TMC data is sprinkled among NMEA strings separated by "?"

The SW I use (iGO8) needs GPS and TMC on separate ports, so I split the original signal with XPort and feed iGO with the virtual ports

**Curiosity** · 02-28-2008, 06:37 PM

That can't be good. There is mixed text and binary in it. I see 3F D5 .... 3F inserted in the middle of NMEA sentences which should be causing problems with your software. It won't be able to find the TMC data in all that mess. It's kind of like 2 things are sending messages that don't know about each other. Try to find some kind of option that is designed to allow them both to work together if there is one. There could also be a baud rate setting for the TMC or second output that is different, but I really think it's made to output on seperate ports.

the funny thing is, it does. If I set a splitted port as TMC port in iGo and do not configure GPS properly, iGO receives TMC correctly.
ShowGPS receives NMEA and TMC on one port so the data seems to be correct.

Does XPort somehow parse/analyze received data or is it forwarded raw to the virtual ports?
