- [RC232] “We are drawing a new board which used your module RC1180. We are in a final phase. For the interface with the our µC, we connected only the pins : – RxD & TxD for module configuration and normal use for communication – Pin Reset, Pin 19, Pin 20 : for future programming (case of firmware update) Also, we connected the pin Vcc and ground with recommandations described in your data sheet. I would like to know, if we can use functions of test carrier transmit, modulation transmit and permanent receipt with only the pins RxD and TxD (RTS, CTS and config not connected to our µC but available on test pads). Do you have a procedure to put this module in test mode. For a firmware upgrade, could you confirm us that we need only Pin 19, 20 and reset ? “
- [RC232] “I have a question for the RC2500HP-RC232, which seems not to be listed in the datasheet. We have the RC2500HP-RC232 connected to a supply voltage of 3.3v. Which voltage will the uart tx output from the RC2500HP-RC232 be? We found a other note on your site, that suggested that it would only have 2.7v on the uart tx pin, even though the module was supplied with 3.3v. “
- [RC232] Can you give a guidance on the range in a city and non-line-of sight?
