[RC232] Are the modules full duplex ? Module is half duplex. Sent and receive but not at the same time. Last Update: August 8, 2017 February 3, 2017 2312 RC232 Q&A Related Knowledge Base Posts -[RC232] I’m not currently using flow control, and am having an issue in correctly identifying the start of each 64 byte packet. My understanding of CTR/RTS is that they wouldn’t help in this? Is there a signal that shows the start of each packet?[RC232] For EN 300 220, which “receiver category” (1, 1.5, 2 or 3) has been used for conformity assessment of RC1240?[RC232] In the Datasheet of the RC11XXHP-RC232 Module it is written that the Module is “Designed for EX compliance”. What does this mean?
