In the technical specification of NetDuino Mini, pins 1 to 4 are mentioned as RS232 pins, specifically pins 1 and 2 for TX and RX. Does this imply that I can get RS232 connection by simply connecting these pins to corresponding pins on a RS232 cable?

I assume for pins 11 and 12 (UART1 TX, RX) a TTL/RS232 adapter is required to convert TTL to RS232 and vice versa. Please correct me if I am wrong.

Also, is NetDunio Mini a discontinued product? I see many small and useful applications using this product, and it would be unfortunate, if it is discontinued.

Thanks.

Question 1 is yes, but cross connect them TX-RX, RX-TX and GND. You do need a TTL/RS232 adapter for COM1 if you want to use your RS232 cable for both ports.

Baxter, thanks for the reply.

Any idea of the availability of the product in the future?

As far as I know, there are no plans to discontinue production.
