Communication Interfaces
The RT207 can communicate with the host device via its TTL-232 interface. This interface is applicable to
most system architectures. For those requiring RS-232, a TTL-232 to RS-232 conversion circuit is needed.
The RT207
’
s TTL-232 interface supports baud rates from 1200bps to 115200bps; it does not support
hardware flow control. Its default settings are 9600bps, 8 data bits, no parity check and1 stop bit.
Besides, if use simulation kit board together(optional), the RT207 can also communicate with the host
device via its USB interface.
1. USB HID-KBW: Based on USB connection, the RT207
’
s transmission is simulated as USB keyboard input.
It works on a Plug and Play basis and no driver is required.
2. USB COM Port Emulation: The USB interface on the host device is emulated as a serial port with the
same data transmission and configuration as a real serial port. A driver is required.
