About this product
- INTERCHANGEABLE NUTS & SCREWS: Secure the adapter to serial devices using the pre-installed DB9 screws, or install the included DB9 Nuts for compatibility with serial peripheral devices/cables; Add two DB9 RS-232 ports to a computer, using a USB-A port
- LED INDICATORS: Each port has dedicated Transmit and Receive LED indicators offering real-time monitoring of port activity, while the USB LED indicates when the adapter is successfully recognized by the desktop or laptop
- COMPATIBILITY: Works with Windows, macOS, ChromeOS, and Linux; Drivers auto-install in Windows 7+, macOS 10.15+, and Linux; COM retention enables the COM port to automatically re-assign if the cable is disconnected/reconnected or if the system is rebooted
- BUILD QUALITY: One-piece molded TPE housing and Level-4 ESD protection (15kV air/8kV contact) enhance reliability and longevity; Copper shielding minimizes EMI/RFI interference; Gold-plated connectors; Extended operating temperature of -40°C to 80°C
- TECH SPECS: 2x DB9 RS232 Ports; 6.5ft (2m) cable length between hub and peripherals (13ft/4m total product length); FTDI FT2232H Chipset; Max Baud Rate: 921.6Kbps; 4KB FIFO; Odd/Even/Mark/Space/None Parity Modes; 7 or 8 Data Bits; 1 or 2 Stop bits
Add two RS232 serial ports to a laptop or desktop, using an available USB-A port
Add RS-232 serial communication support to USB-A enabled Data Terminal Equipment (DTE - e.g., desktop or laptop), using this 13ft (4m) straight through 2-Port USB to Serial Adapter Cable.
Serial Port Expansion
The Dual-Port USB Serial Adapter adds two RS-232 serial DB/DE-9 (male) connectors to a desktop or laptop via a single USB Type-A port. Secure the adapter to a serial device, using pre-installed and removable slotted D-Sub thumbscrews or install the included DB-9 Nuts for compatibility with other serial peripheral devices or cables.
LED Indicators
Data transmission and reception LED indicators for each port on the adapter provide real-time monitoring of port activity. The USB LED indicates when the adapter has successfully enumerated on the desktop or laptop. All the LEDs aid with diagnostics and troubleshooting.
Seamless Connectivity
The adapter is compatible with Windows, macOS, ChromeOS, and Linux. Drivers automatically install to Windows 7 and newer versions, macOS 10.15 and above, and Linux. The USB to RS-232 adapter features COM retention, which automatically reassigns the COM port value if the cable is disconnected and reconnected, or if the system is rebooted.
Built To Last
The rugged TPE construction and Level-4 ESD protection (15kV air and 8kV contact) enhance the reliability and longevity of the USB to Serial Adapter. Copper shielding minimizes Electromagnetic and Radio Frequency Interference (EMI and RFI). Gold-plated connectors enhance signal conductivity. The included mounting bracket allows the hub of the serial adapter to be mounted to a desired surface.
