Using USB Serial Ports
An interface once commonly used to access external hardware is an RS232 serial port. This type
of interface was once used to connect a variety of devices to a desktop PC such as printers, mice,
barcode scanners, and NFC readers. The low hardware and software cost of adding this type of
device makes this type of interface still attractive in many devices.
The majority of serial ports use a device referred to as a Universal Asynchronous Receiver
Transmitter, or UART for short. This device manages the sending and receiving of data.
There are many standards for serial communications. The RS232 standard defines the most
common electrical levels and types of connectors used.
There are several USB UART Adapters available on the market compatible with Android.
The LAVA Tablet Manager v4.** and v5.** have special support for single and multiple user-
supplied serial ports. If your system is using a USB serial port, please contact LAVA for
additional information.
