Hi Ron,
well, after setting up the receiver with the TSIPCHAT (without battery backup) to use NMEA output 4800 8N1, i have powered it off for 24 hours, then conect back to PC with serial port monitor and there is still NMEA sentences being output at 4800 8N1.
I have not used the serial output string from Trimblebut wonder why they dont use packet 8E-26 which is non-volatile memory storage at the end.
I'll took it for granted that it works for you, and waiting news of gps string parsing and filtering.
I forgot one more question as I move forward to connect SQ to PIC, how do you connect them, use level shifter like max232 or directly ?
thanks
claxon
