Add two RS232 serial ports to a laptop or desktop, using an available USB-A portAdd 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 ExpansionThe 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 IndicatorsData 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 ConnectivityThe 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 LastThe 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.The StarTech.com Advantage

Reliably connect high-bandwidth HDMI 2.0 devices through plenum spacesRoute this Active High Speed HDMI 2.0 Cable through office plenum spaces for long distance transmission of 4K 60Hz video and high quality audio.HDMI UHD Over Long DistancesThe Active HDMI 2.0 cord is designed for long-distance reliability. Durable gold-plated connectors and 24/28AWG bare copper wire maintain optimal conductivity and low resistance, ensuring consistent performance across different environments. The integrated active chipset boosts the HDMI signal without requiring external power, facilitating 4K 60Hz video and full HDMI 2.0 capabilities. This enables the transmission of HDMI UHD video beyond passive cable lengths.Full-Featured HDMI 2.0The Active HDMI UHD Cable supports full HDMI 2.0 specifications:• Up to 18Gbps bandwidth for 4K 60Hz video and higher refresh rates at lower resolutions (e.g. 1080p/1440p 120Hz)• High Dynamic Range (HDR10) with 10-bit processing for higher contrast ratio and vibrant, cinematic picture quality• Audio Return Channel (ARC) for 7.1 and 32-channel audio• High-Bandwidth Digital Content Protection (HDCP 2.2) for a secure connection between source and display• Dual Video Streams enable two independent video streams from a single source, allowing for picture-in-picture and other capabilities• Variable Refresh Rate (VRR) synchronizes the refresh rate of the display with the output frame rate of the content, reducing screen tearingPlenum-Rated CablingThis HDMI 2.0 Cable features a Communications Multipurpose Plenum (CMP)-rated cable jacket with low-smoke characteristics. It is ideal for use in the plenum spaces of buildings (e.g., dropped ceilings and in-wall installations). The durable outer jacket is rated to withstand over 1,000 bending cycles at -/+60 degrees. This protects the cable from damage when routing through tight spaces that include multiple bends.Note : This cable is unidirectional and must be installed in a specific direction. Refer to the embossed SOURCE and DISPLAY markings on the HDMI connectors to ensure that each end corresponds with the correct hardware.The StarTech.com Advantage
