Technical Overview
This adapter delivers serial communication with a maximum baud rate of 921.6Kbps, supporting configurable parity modes (Odd/Even/Mark/Space/None), 7 or 8 data bits, and 1 or 2 stop bits. The FTDI chipset includes 128-byte RX and 256-byte TX FIFO buffers to manage data flow efficiently, reducing potential bottlenecks during continuous transmission.
COM retention functionality automatically reassigns the COM port upon reconnection, maintaining consistent device addressing in Windows environments. LED indicators provide real-time visibility into transmit, receive, and USB recognition status, aiding troubleshooting and operational monitoring.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages
This adapter stands out with its robust construction and thoughtful design for professional and industrial use. The interchangeable DB9 nuts and screws allow secure attachment to serial devices or compatibility with peripheral cables, eliminating the need for separate hardware.
Enhanced Reliability
A solid one-piece molded TPE housing combined with Level-4 ESD protection (15kV air/8kV contact) safeguards against electrostatic discharge. Copper shielding minimizes EMI/RFI interference, ensuring signal integrity in electrically noisy environments.
- TPE Molded Housing
- Level-4 ESD Protection
- EMI/RFI Shielding
Broad Device Support
The adapter works with a wide range of serial devices, including desktop computers, notebooks, monitors, barcode scanners, receipt printers, POS devices, digital signage, sensors, and other peripherals. This versatility makes it suitable for retail, industrial, and office applications.
- POS Systems
- Industrial Sensors
- Legacy Peripherals
Deployment / Use Cases
This USB to serial adapter is ideal for environments where legacy serial devices must interface with modern computing systems. Its null modem configuration simplifies connections between data terminal equipment (DTE) and data communication equipment (DCE), common in serial communication setups.
In retail and hospitality, the adapter connects barcode scanners, receipt printers, and POS terminals to USB-only computers, extending the lifecycle of existing serial hardware. Industrial applications benefit from the extended operating temperature range (-40°C to 80°C) and rugged design, supporting sensors, controllers, and monitoring equipment in demanding conditions.
Retail & Point-of-Sale
Integrate legacy serial barcode scanners, receipt printers, and cash drawers with modern POS computers or tablets, avoiding costly hardware replacements.
Industrial & Embedded Systems
Connect serial sensors, PLCs, or diagnostic tools to laptops or embedded controllers for data acquisition, monitoring, and control in manufacturing or field service scenarios.

FAQ
How does COM retention work with this adapter?
COM retention ensures the adapter's COM port number remains consistent after reconnection or reboot in Windows. When the adapter is unplugged and reconnected, Windows automatically reassigns the same COM port, preventing configuration conflicts in applications that rely on fixed port assignments.
What is the maximum data transfer rate (baud rate) supported?
The adapter supports a maximum baud rate of 921.6 kilobits per second (Kbps). It also configures parity modes (Odd, Even, Mark, Space, None), data bits (7 or 8), and stop bits (1 or 2) to match connected serial device requirements.
Can I use this adapter with industrial equipment in harsh environments?
Yes, the adapter's extended operating temperature range of -40°C to 80°C, Level-4 ESD protection, and copper shielding make it suitable for industrial use. The rugged TPE housing resists physical stress, while gold-plated connectors prevent corrosion in humid or variable conditions.
What devices are compatible with this USB to serial adapter?
Compatible devices include desktop computers, notebooks, serial adapters, peripheral devices, sensors, monitors, barcode scanners, receipt printers, POS devices, and digital signage. It supports both data terminal equipment (DTE) and data communication equipment (DCE) with its null modem configuration.
What is included in the package with the adapter?
The package contains the USB to Serial Adapter, two DB9 screws for alternative attachment, and a quick-start guide. The adapter comes with pre-installed DB9 nuts, and the screws provide compatibility with devices or cables that require screw-fastened connections.
What refresh rate or brightness details are available?
Display-oriented products are best judged through screen, connectivity, and installation specifications. Those facts help buyers confirm visual fit, mounting flexibility, and deployment suitability more clearly than generic summary text.
