Keep Your Legacy Systems Running
The TECHTOO 4-Port USB to RS232 Serial Adapter bridges the gap between older serial hardware and modern computers. It allows you to connect up to four 9-pin serial devices, such as modems, GPS receivers, or point-of-sale systems, to a single USB port. This adapter is powered directly by the USB connection, eliminating the need for an external power adapter and simplifying setup.
Engineered with a high-speed FTDI chipset, this adapter ensures reliable data transfer rates of up to 1Mbps. It supports automatic handshake and maintains COM port assignments across reboots, providing a stable connection for critical applications. The included hexnuts offer a secure, male-to-male DB9 connection, suitable for industrial and networking equipment.
This adapter is compatible with a wide range of operating systems, including Windows (8.1/8/7/Vista/XP/2000), Android, Linux, and Mac OS X 10.6 and above. It's plug-and-play after initial driver installation, making it easy to integrate into various environments. While it supports many serial devices, it does not support serial mice requiring IRQ or I/O addresses.
Bridge Legacy to Modern Tech
This TECHTOO adapter ensures your essential older serial equipment remains functional with contemporary computers. It's designed for robust connectivity, featuring a genuine FTDI chipset for dependable data transfer. Unlike generic adapters, it offers stable COM port retention and broad OS support, making it a trustworthy solution for industrial control, networking, and scientific instruments. Imported directly from authorized US retailers, it guarantees authentic performance for critical applications.
Ideal For Technicians & IT Pros
This adapter is perfect for IT professionals, network administrators, and technicians who need to connect to routers, firewalls, or industrial machinery with RS232 ports. It's also suitable for hobbyists working with GPS devices, telescopes, or embedded systems. Skip this adapter if you only need to connect a serial mouse, as it does not support IRQ or I/O address requirements for such devices.
