I'm putting a new kit together and would like some feedback.
Maxim makes a MAX3160 IC $17 that has both an RS232 & RS485 selectable interface (also includes RS422 but I'm not going to offer that)
Seems like a pricy part as the kit will only offer one or the other when sold (user could pull the socketed part and swap in their own so...)
* I guess I'm answering my question as I type this
Jumpers to select RS232 / 485 (slightly higher cost)
or simply only install the IC ST232 or SN75176 depending on your requirements.
I'll use a DE9 connector though, just like the MAX3160 schematic.
**broken link removed**
* Incase you missed it I'll avoid the MAX3160 as it would be the most expensive part in the kit!
