Connecting Software to theInternal GPSThe internal GPS receiver has two serial ports which connect tothe LT500T’s internal COM1 and COM6 ports. Both ports arealways active. Commands can be sent to either port, and NMEAstrings can be streamed from either/both ports.By default, the baud rate for each of the ports (COM1 and COM6)is set to 38,400. If you connect SurvCE to the internal receiverusing the ‘CHC’ ‘LT500T’ driver, SurvCE will set the baud rate to9600 baud. We strongly recommend that you don’t use theSurvCE internal driver and instead use the NMEA driver.You can control which NMEA sentences are sent to each portusing LTSet.iGage LT500T User Manual29
