StarTech ICUSB2321F USB to Serial RS232 Adapter Cable
Overview
The StarTech ICUSB2321F is a 6-foot USB to RS232 serial adapter cable, built with an FTDI FT232RL chipset. This adapter bridges the gap between modern USB ports and legacy serial devices, providing a reliable serial communication link. It's designed for applications where you need to connect serial equipment, such as industrial controllers, point-of-sale devices, or older surveillance equipment, to a computer that lacks a native serial port. The inclusion of COM port retention ensures that the assigned COM port number remains consistent across reboots, critical for systems that rely on specific port assignments.
Compatibility
This adapter is compatible with devices requiring an RS232 serial connection. It supports data bits 7 or 8, with parity options including None, Odd, Even, Mark, and Space. Stop bits can be configured as 1 or 2. The maximum baud rate supported is 115.2 Kbps. It connects via a standard USB 2.0 Type-A port on the host computer and terminates in a male DB-9 connector for the serial device. The 256-byte FIFO buffer aids in efficient data transfer.
Installation Notes
Operating temperature range is 0°C to 55°C (32°F to 131°F), with storage temperatures from -20°C to 85°C (-4°F to 185°F). It functions within a humidity range of 5-95% RH. The adapter itself has compact dimensions of 1.6 inches wide by 0.9 inches high.
