2. Detailed Description

The interface specification between the product and a Host controller is described below.

2-1. Connection format

2-1-1. Physical connection

Host (Controller) Slave (the product)

(Serial setting <RS232C basic>)
Baud Rate : 9600bps
Data Bits : 8bit
Parity : None
Stop bit : 1bit

Handshaking : None

2-1-1-1. Data transmission sequence from Host to Slave

Host (Controller) Slave (The product)

TxD → RxD

RxD ← TxD

1. Host starts a data transmission from TxD.

2. Host performs the data transmission of the number of required bytes, and ends a transmission.

2-1-1-2. Data transmission sequence from Slave to Host

Host (Controller) Slave (The product)

TxD → RxD

RxD ← TxD

1. Slave starts a data transmission from TxD.

2. Slave performs the data transmission of the number of required bytes, and ends a transmission.
