Connects Up to Four 9-Pin Serial Devices to Your Computer, Laptop or Tablet's USB-A Port

This USB to serial converter turns your computer's USB port into four DB9 ports capable of connecting RS-422 and RS-485 serial devices, such as modems, handheld scanners and GPS systems. No external power source is needed. Just connect the included USB cable between the U208-004-IND and your computer, and insert the included CD into your computer's CD drive in order to launch the driver. You'll be able to configure and share data among point-of-sale equipment and other serial devices. LEDs indicate when serial data is being sent or received.

Independent DIP Switches for Easy Port Configuration

The U208-004-IND's serial ports can be set to automatically detect an RS-422 or RS-485 device by adjusting their DIP switch settings. The ports can also be set specifically for use in 4-wire mode.

COM Retention Feature for Convenient Reassigning of COM Values to Ports

This USB to RS-485 adapter with built-in FTDI chipset offers COM retention. It automatically reassigns the same COM port values to each port, so when the cable is disconnected or the system is rebooted, no additional configuration is needed. The cable auto-detects and auto-switches RS-422 and RS-485 devices. It also supports RS-485 auto-transceiver turn around with unique featured ATTA hardware.

Rugged All-Metal Housing Designed to Last in Harsh Industrial Applications

The wall-mountable USB to serial converter with an industrial-grade steel enclosure offers electrostatic discharge (ESD) protection to ±15kV. It supports serial communications speeds up to one Mbps and USB 2.0 specifications, though it is backward compatible with USB 1.1 devices.

2-Year Warranty

The U208-004-IND is backed by a 2-year warranty, ensuring reliability and performance.

The LAVA Parallel Bi-directional has been a Lava product since 1984. Since that time, the board has gone through relatively few design changes. Other than gaining an 8-bit bi-directional mode, it is functionally identical to the original Lava Parallel. In the fast-moving world of computer hardware, that might be some sort of a record! The board has been hailed as the most reliable bi-directional product on the market with the widest range of operating system support.

Ideal for systems where manual settings of IRQ and COM addresses is a must, the LAVA DSerial-550 doubles the serial ports in a system short on ISA slots. Offers a generous selection of IRQ and COM port settings to minimize potential conflicts in resource allocation.
