[Elecraft] re TCP Port for KPA500 and KAT500

[John Newgas]

I can’t help with whether the ports are hard coded or not … but I can give you a neat solution.

You can  use a low cost raspberry Pi with a couple of USB to Serial adaptors to link to the KPA500 and KAT500

The free software ser2net will give you a direct interface from the TCP/IP to the serial ports.

Configuration is pretty easy and basically two lines like 
4626:telnet:600:/dev/ttyUSB0:19200 8DATABITS NONE 1STOPBIT banner
4627:telnet:600:/dev/ttyUSB1:19200 8DATABITS NONE 1STOPBIT banner

You can connect to the TCP/IP side of the Raspberry Pi through WiFi or Ethernet from your main router, but  you would have to open those ports inside the router.

I run my KX3 remotely like that without problems ( higher baud rates work well for me )
