Hi,
I have tried every permutation I can think of at this point and tested multiple hardware devices. In summary there seems to be an issue with serial comm’s via the GX450 Normal mode Serial Port.
I have a device connected to the serial port that transmit a standard NMEA-0183 String:
Example:
$PMPPTDAT,1.0.3-EXP,4288,4558,4293,0,0,23,23,23,25,5,0,4288,4657,0,16,0,16,0,1,0,3604,0,0,0,0,0,4938,0,1,10,6,0,3418,0,4556,4270,4380,0,0,0,0,0,1,2097,5288*71
However, when I try to use my GX450 system I get some good and some garbled data.
Example:
$PMPPTDAT,1.0.3-EXP,4288,4558,4293,0,0,23,24,24
25(4,0,4289,4647,0,16,0,!6,0,1,0,3604,0,0,0,0,0,0939
0,!,1 ,6,0,3418,0,4556,4270,4380,0, ,0,0,0,1,2097,528870

Any Help would be seriously appreciated!
