If you intend to transmit data only one way you need one pair: one transmitter and one receiver .. Here are examples: https://www.8051projects.net/e107_files/public/1238686774_5507_FT20623_mo-rx3400.pdf https://www.8051projects.net/e107_files/public/1238686774_5507_FT20623_st-tx02-ask.pdf https://www.8051projects.net/e107_files/public/1238686774_5507_FT20623_rlptlp.pdf Connection is pretty straightforward: Tx of one 89C51 goes to Data-In of the Transmitter module and Data-Out of the Receiver module goes straight to Rx of the second 89C51 ..
