If you have the Seatalk to USB converter, then you can plug this straight in to a Windows, LINUX or Mac computer and use a Telnet Terminal type program to send this command. If you have the Seatalk to NMEA0183 converter, you need to use a NMEA 0183 to USB Adapter.

On a Mac we use CoolTerm which is freeware by Roger Meier…

You need to make sure that CoolTerm is set to send CR+LF as the Enter (EOL) characters, as this is always used in NMEA 0183 systems to indicate the end of the sentence has been reached.

Then copy the command: $PDGY,STalk,On

And paste it into CoolTerm or any Telnet Terminal Type program and the mode should change.

• If you have the Seatalk to USB converter, then you don’t need any extra cables

• If you have the Seatalk to NMEA 0183 converter then you will need an NMEA0183/RS422/RS232 to USB adaptor cable, but the procedure is the same.

1. Please download the Tech Note that explains the procedure. It is the same procedure for our ST-NMEA, iKonvert and GPS160 products, that all have an STM32 micro.
2. Also download the latest V2.08 firmware. This is a ZIP file which you will need to unzip and there is just one BIN file inside. This is the file that you upload to the ST-NMEA converter.
