I am really, really happy that Jason brought back the SMT TARPN NinoTNC back into production. It makes the NinoTNC accessible for those that aren't comfortable soldering and troubleshooting their build. I understand that building it yourself from mostly through-hole components was a design goal of the NinoTNC, but the SMT TARPN NinoTNC really makes that technology more accessible.
Nice to see a small compact unit back on the market. However, can we understand that 'bit rate' and 'baud rate' are not the same in all cases? The rates that you speak of in your documentation are actually the bit rate. In some modulation methods, such as 2400 DPSK, where 2 bits are coded at a time, the baud rate is actually the symbol rate, which in this case is 1/2 the bit rate. Granted some are the same when one bit is encoded at a time, but in higher orders of modulation this is not the case. For example, 14.4Kb modems actually had a baud rate of 1200.
Please note that RPC Electronics SMT TARPN NinoTNC has been discontinued. Only the original thru-hole version of the NinoTNC remains.
We're bringing the SMT NinoTNC back. The website has been updated to show this and we'll start taking orders in about a week...
