Overview

The US-101 is a robust USB-to-RS232 adapter designed to provide a single high-speed serial port for industrial and commercial environments. It features a DB9 male connector and is capable of data rates up to 1 MBaud, making it suitable for modern high-bandwidth serial applications. The device is powered directly from the USB port, drawing approximately 40mA at 5V, which eliminates the need for an external power supply.

Why Choose This Part

This adapter stands out with its high-speed performance, supporting baud rates up to 1 MBaud far exceeding standard 115.2 kbps limits. Its 89mm length provides a compact form factor for tight industrial cabinets, and the manufacturer provides a lifetime warranty upon registration for long-term reliability. The device is optimized for stability across a 0 to 50 degrees Celsius operating range.

Applications

PLC Programming and Monitoring
Ideal for connecting modern laptops to industrial Programmable Logic Controllers that utilize RS232 communication ports.
Lab Instrument Integration
Facilitates data collection and control for older laboratory equipment like scales, sensors, and analyzers that lack native USB support.
Point of Sale (POS) Systems
Connects peripheral devices such as barcode scanners and receipt printers to a centralized USB-based computer system.
Field Service Diagnostics
A portable solution for technicians needing to interface with serial consoles on networking gear or industrial machinery in the field.

Getting Started

Installation is straightforward as the device is plug-and-play compatible with most modern operating systems which automatically download the necessary FTDI or Prolific drivers. Once connected, the adapter appears as a standard COM port in the Device Manager, allowing it to be used with any terminal emulator or custom software. For industrial reliability, ensure the DB9 thumb screws are tightened to prevent accidental disconnection during vibration.
