RS3 base output (RTCM3)

I set up RS3 to output RTK correction signals via serial cable (Part number CBL102). I made a capture of that correction signal in binary. Here is an example of that. all in hex format.

Notice that the message starts with 0x16 and 0x77 where I’m expecting 0xD3 and 0x00, based on RTCM specs.

So I’m confused here, what exactly RS3 is output? Is this proprietary correction message?
Here is my RTCM message set up. I made this screenshot after I got a fix and moving RS3 indoors. just to capture a screenshot.


My serial port setup is baudrate 38400, 8N1.

Hi,

You could check RTCM3 binary log by WAY service.

Thanks for providing the link, I tried, but no luck.

Could you share the log please?

Thanks for your help. I got it fixed. the log I capture is corrupted. The reason is I didn’t us a correct RS-232 to USB serial cable.
My laptop doesn’t have DB9 port, so, my connection is
Emlid RS3 —> CBL102 —> DB9 to USB cable —> Laptop USB port.

The cable (DB9 to USB cable) is the root cause. Originally, I’m using a FTDI, C232HD-DDHSP-0 cable, but I realize it’s not the right one.
After I switched to a Z-TEK RS232 to USB cable, everything looks good. I start to see 0xD3 0x00 RTCM messages.
