- [RC232] In order to save costs, the customer need to make a only one board that can accept the different devices: RC1240 or RC1701 / RC1701HP or RC1740 / RC1740HP or RC1780 / RC1780HP or RC11x. Could you supply a final schematic for all pins (series resistors, pull-up, diode etc.)?
- [RC232] Is the operation with RC1180HP module license free in Germany and in EU?
- [RC232] 1. How does the RC1180-RC232 react as the supply voltage reduces below the minimum operating voltage and below – the system is powered by a Solar cell secondary cell to hold charge short to medium term. It is possible the secondary cell will start to discharge beyond the requirement for operation – does the module need to be unpowered to protect it from brown-out situations.
