  • Includes type FT232R UART with 128-byte receive/256-byte transmit FIFO buffers
  • Supports 7 or 8 data bits, 1 or 2 stop bits, and odd /even / mark / space / no parity
  • ±15kV ESD Protection (IEC 6100) on all RS-232/422/485 signals protects against spikes and ground loops
  • Fully shielded cable protects data from EMI and RF interference
  • Software programmable baud-rates
  • All required power drawn from host USB port, no external power adapter required
  • Supported for use in Windows (including Windows CE) and Linux operating systems

USB-232-IND

  • Supports all RS-232 signals, including handshaking
  • Data transfer speeds up to 1Mbps asynchronous

USB-422-IND

  • Supports full-duplex (4-wire) RS-422 protocol
  • Data transfer speeds up to 3Mbps asynchronous

USB-485-IND

  • Supports multi-drop (2-wire, half-duplex) RS-485 protocol
  • Data transfer speeds up to 3Mbps asynchronous

FACTORY OPTIONS

  • RC Termination to prevent ringing and reflections (RS-422 and RS-485 models)

The USB to serial IND series are rugged, industrial, serial communications adapters designed for use in demanding real-world applications such as transportation, military, embedded control systems, remote data acquisition, mobile, and more. These intelligent modules provides a cost-effective solution for transferring high-speed asynchronous serial data over USB. Use legacy serial devices with any PC or embedded system with a USB port. The adapters provide easy connectivity between the computer and standard communication ports or remote serial devices. No PC reconfiguration, assignment of IRQs, or jumper settings required. The adapter will be recognized as a USB to Serial Adapter and install in the system as a standard COM port.

Accessories

The ADAP9 accessory provides a screw terminal connection to break out the RS-232, RS-422, and RS-485 signals on the DB9M connector.

Connections to System

The USB serial converter is equipped with a 6 foot, fully shielded USB cable, a USB type A connector for connection to a computer USB port, and a male DB-9 for connection to a RS-232, RS-422, or RS-485 equipped data or communication terminal.

SOFTWARE

The USB serial converter installs into any operating system as a standard serial COM device, allowing all 3rd party software to operate the serial port as usual. Samples in a variety of languages and environments are provided, including a Windows utility "WinRISC", a "Really Incredibly Simple Communications" terminal program. Drivers are provided for Windows (including Windows CE) and Linux, and are available at no cost for most other operating systems.
