No GPS signal on 2nd computer

[Han van Vliet]

I am looking for a configuration were the GPS is working on an other computer.

FS9 computer

• Com-port via PCI card and a “ standard” Com-cable

• Using PortMon I see that GPSout is sending information to com3 port

2nd computer

• Installed: Mapsource 6.5, Jepessen Flight Map 9.04, MS Autoroute 2005

• Via port programs are looking for information on the com1 port, but can not find a GPS

Both com-ports have the same configuration/settings, Windows XP standard.

Who has some Ideas how this can work?

Thank for the help.

What do you mean by "standard" COM-cable? There's no one "standard".

Most serial cables are intended to link a PC to a serial device like a modem. Such a cable has parallel connections -- one end is a DCE the other a DTE pin arrangement, meaning pins 2 and 3 have opposite functions at each end.

Extension serial cables are similar but have a male connector one end and female the other. Again, the links are parallel.

To link two PCs together you have to use what is commonly known as a "null modem" cable -- called this because it can link two PCs without a pair of modems between them. Really only 3 wires are needed - common (pin 1 or shield), and pins 2 to 3 and 3 to 2 (crossing over the RX to TX and TX to RX).

This is mentioned in the text file provided with GPSout.
