4. HOST INTERFACE

The host interface of ACT-IR100SD is a full-duplex asynchronous RS232 DB9M connector. The following table is the signals of DB9M connector. It can be treated as DTE. The data bytes are transmitted via TXD pin and received via RXD. Each data byte consists of one start bit (0), 8 data bits (LSB first, MSB last), a stop bit (1) and no parity bit.

Implementing H/W flow control signals in host end is recommended. Since ACT-IR100SD is a buffer limited dongle. Without flow control will probably cause data loss sometimes. The H/W flow control relative signals are: DTR, RTS, DSR and CTS, which are defined exactly as RS232 DTE interface.
