Re: [44net] Making Packet Node with Pi ?

A few notes: 1) There is a TNC board for the RPi: http://tnc-x.com/TNCPi.htm and it supports stacking multiple TNCs on a single RPi. It's a pretty elegant solution. 2) The RPi has UART pins on the I/O connector. All you need is a RS232 to LVCMOS level converter. The only disadvantage to that is that you can only connect a single TNC unless you go to NETROM firmware on the TNCs. 3) Using USB<->RS232 converters should work but do yourself a favor and avoid any adapter that is based on the Prolific chipset. The number of fake Prolific devices on the market is unreal and their drivers are very suspect. Use FTDI based devices as they have done a good job of protecting their IP and maintaining a stable driver set for Windows and Linux.

(Please trim inclusions from previous messages) _______________________________________________ Hi there Is there a way to have a Packet Node with Pi (or any other small size solution that will not require a PC) ? If yes How do I connect TNC (serial port) to PI is the Pi support USB to serial external interface (like the profilic ones) ? Or (preferred) something can be done to do the TNC on Sound card (can be an External sound card that connect to the USB of the PI) Please Advice Thanks Forward Ronen - 4Z4ZQ jttp://www.ronen.org
