First question would be: Does the Green LED flash for some time, then go solid?
? If not, then the TT4 is not getting the GPS data.
Are you using a splitter that allows both computer and GPS?
?? The Byonics splitter has a port for the computer and one for the GPS with proper connectors.
?? Without a splitter, you must configure AMODE and ABAUD must be set to the GPS configuration.
?? BMODE and BBAUD won't matter without the splitter
???
NOTE:? The TT4 always starts out at 19200 baud and after initialization, changes to the ABAUD and AMODE settings.? This means you can still make settings change on PORT A, even if it is set to GPS.
If that isn't it, you need to provide more details:
?? What firmware is in the TT4?
?? Explain you connections to GPS and radio
?? Post your settings and we can review them to provide more comments.
