Could you give us some advice on that? “[RC232] “i have some questions for RC1701HP-RC232. Need the “tx” pin a levelshifter or driver-ic (our previous experience with RC1280 was a f—ing 100KR impedance!!!) ? Are on the “tx”, “rx” and “cts” pins resistors in series? Can I connect “tx”,”rx” and “cts” directly to a MCU (XMEGA @ 3,3V)? “[RC232] Do you have an Unlimited modular approval FCC / IC + EN Test results?
