Detailed Description The interface specification between This product and a Host controller is described below. 3-1. Connection format 3-1-1. Physical connection Host (Controller) RTS Slave (This product) CTS CTS TxD RxD GND RTS RxD TxD GND (Serial setting ) Baud Rate : 9600bps Data Bits : 8bit Parity : None Stop bit : 1bit Handshaking : (RTS/CTS) 3-1-1-1. Data transmission sequence from Host to Slave Host (Controller) Slave (This product) RTS → CTS CTS ← RTS TxD → RxD RxD ← TxD 1. The host checks that CTS is High, then starts a data transmission from TxD. 2. The host performs the data transmission of the number of required bytes, and ends a transmission. * The host can do RTS to Low during the transmission for disable data transmission from a slave. 3-1-1-2.
