NMEA output on LC29T-AA EVB

My LC29T EVB does not output anything on the USB-Serial port (CP2102) using 115200 baud rate and does not respond to any commands sent from QGNSS V1.10, so i can’t even check the firmware version. The EVB PCB differs from LC29H EVB only by the third SMA 10MHz clock output connector. Which firmware is used by the LC29T and where can i get the user manual ?

Hi Helg

Did you see port information from Device Manager in Windows system after EVB connect to PC?

Did you see the LED on EVB blinking after swith on?

I attach the driver for Windows system. If you don’t see port in Device Manager, you can download and install the driver.

Dear Raphael,

the POWER(red) and VCC(green) LEDs are on.
The 1PPS(red) LED does not blink, the TXD(green) LED blinks once, if i press the RESET button(S502).
USB COM port is detected, CP2102N driver is installed and works. I have tested it under Windows and Linux.
Without the schematics i don’t know what are the right settings for RTS and DTR jumpers.
I can try to flash the LG69T-AA firmware, but it may be a bad idea without having the original LC29T-AA firmware.
The board picture is attached.

Hi Helg,

I will send you the latest firmware for LC29TAA via message.

Best regards.
