Thank you for purchasing this USB Host to RS232 Adapter Cable (the
“
Adapter Cable
”
). It is designed specifically to support Android Open
Accessory protocol. The Adapter Cable connects to a USB device on
the Android platform, establishes the USB connection, enumerates
Open Accessories, and then provides a bridge from the USB host port
to a UART interface. All necessary USB and Android Open Accessory
protocol is incorporated in the chip built-in the Adapter Cable, so
that users can quickly and easily establish a USB connectivity link and
have a basic UART (RXD, TXD, RTS, and CTS signals) interface for their
applications.
Android Open Accessory Protocol is supported in Android
Honeycomb (3.1) and later versions, with the benefit that data can
be transmitted and received without additional driver support.
