Description

StarTech ICUSB422 USB to RS422/RS485 Serial Adapter Cable

Overview

The StarTech ICUSB422 provides a robust USB 2.0 to RS422/RS485 serial communication link, essential for integrating legacy industrial equipment or specialized surveillance devices into modern networks. This adapter is built around the reliable FTDI FT232RL chipset, ensuring stable data transfer for applications requiring direct serial control or data acquisition, such as connecting to specific PTZ camera controllers, environmental sensors, or industrial automation hardware that relies on RS422 or RS485 interfaces. Its 6-foot cable length offers flexibility in deployment scenarios where the USB host is not immediately adjacent to the serial device.

Compatibility

This adapter is compatible with systems running Windows, macOS, and Linux. It supports various serial communication parameters including 7 or 8 data bits, Even, Odd, or None parity, and 1 or 2 stop bits. The maximum baud rate of 921.6 Kbps ensures compatibility with most serial devices, including many older surveillance camera systems that utilize RS422/RS485 for pan-tilt-zoom control or configuration.

Installation Notes

The adapter operates within an ambient temperature range of 0°C to 55°C (32°F to 131°F) and can be stored between -20°C to 85°C (-4°F to 185°F). It requires 5~95% non-condensing relative humidity for operation. The built-in 256-byte FIFO buffer helps manage data flow efficiently, reducing the load on the host system.
