The ANDROID-232 is a USB serial interface board that enables you to control legacy RS-232 devices from your Android devices. The board is well suited for POS, gaming systems, retail, hospitality, automation, kiosks, defense industries, lighting, or any other application requiring the connection of RS-232 serial devices to an Android-compatible system.
The ANDROID-232 uses the Android Open Accessory protocol to “convince” an Android device that its on-board USB port (normally limited to USB slave or OTG modes) is actually an RS-232 port. This two-way data port enables external hardware to control the Android unit or the Android unit to control external hardware.
The ANDROID-232’s key features include an Android USB 2.0 full-speed host-to-industry-standard RS-232 DB9M serial port; support for a UART interface with RX, TX, RTS, and CTS; a 5,512-byte RX buffer size; a 256-byte TX buffer size; ±15-kV ESD protection on USB data lines and all RS-232 signals; status and fault LEDs including external power, charging status, and USB status; a Type-A USB connector; a latching 5-V external power input connector with an external regulated power supply; a –40°C-to-85°C standard industrial operating temperature; and RoHS compliance.
The board includes an Android sample program with source code. This program enables you to verify proper operation of the ANDROID-232 device, including sending and receiving RS-232 data. The ANDROID-232’s Python test program can cooperate with the Android sample program to verify proper receipt of transmitted data.
The ANDROID-232 costs $139.
