[RC232] Are the RC1140 and RC1240 compatible No. They are not compatible. Last Update: August 8, 2017 July 7, 2017 2139 RC232 Q&A Related Knowledge Base Posts -[RC232] Is the internal configuration (internal diode, internal pull-ups, etc) of RC17XX series the same of RC1240 on same pin? I.e, when pin of RC17XX is (functional) the same of RC1240, the internal configuration is the same too? If there are differt configuration, could you indicate it?[RC232] I’ve noticed the label FCC pending on the RC1190HP. Could you please confirm is FCC approved?[RC232] When I connect RXEN and TXEN to VDD, instead of leaving open, the current consumption increases to 20, mA. When I send a character to the module over RS232, the current appears to be 134mA.
