The FTDI FT232R chipset delivers data rates up to 921.6 Kbps with 128-byte receive and 256-byte transmit FIFO buffers, while COM port retention ensures the assigned COM number persists across reconnections and reboots for consistent device addressing in automated environments.\u003c\/p\u003e\n\u003cp\u003eAt 6.6 feet (2 meters), this cable provides working distance between the host computer and serial equipment while maintaining signal integrity through copper shielding and gold-plated connectors. Level-4 ESD protection rated at 15kV air and 8kV contact discharge combined with a -40°C to 80°C operating range makes the cable suitable for industrial floor deployments where static and temperature extremes are common.\u003c\/p\u003e\n\u003ch3\u003eWhere the StarTech 1P6FFCN-USB-SERIAL Null Modem Adapter Cable Fits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial automation connecting to DCE serial devices\u003c\/strong\u003e where the null modem wiring eliminates a separate crossover adapter, the FTDI FT232R chipset supports data rates to 921.6 Kbps for high-speed serial protocols, and Level-4 ESD protection handles electrostatic discharge on factory floors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork infrastructure management via console ports\u003c\/strong\u003e where the 6.6-foot reach connects laptops to rack-mounted switches and routers, COM retention maintains consistent port assignments across sessions, and TX\/RX\/USB LED indicators confirm active data flow during configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint-of-sale and lab equipment requiring persistent serial connections\u003c\/strong\u003e where COM port retention prevents application errors from port reassignment, the DB9 female connector with interchangeable thumbscrews and hex nuts ensures a secure mechanical connection, and the -40°C to 80°C range supports uncontrolled environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the StarTech 1P6FFCN-USB-SERIAL Null Modem Adapter Cable Delivers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFTDI FT232R with 921.6 Kbps Throughput:\u003c\/strong\u003e Professional-grade FTDI chipset with 128-byte RX and 256-byte TX FIFO buffers provides reliable high-speed serial communication with broad OS driver support across Windows, macOS, and Linux.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNull Modem (DCE) Wiring:\u003c\/strong\u003e Built-in crossover configuration connects directly to DCE serial devices without requiring a separate null modem adapter, supporting 7\/8 data bits, 1\/2 stop bits, and odd\/even\/mark\/space\/none parity modes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCOM Port Retention:\u003c\/strong\u003e Assigned COM port number persists through cable disconnections and system reboots, preventing application failures in automated systems that reference specific COM assignments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial-Grade Protection:\u003c\/strong\u003e Level-4 ESD protection rated at 15kV air discharge and 8kV contact discharge, copper shielding against EMI, gold-plated connectors for corrosion resistance, and a -40°C to 80°C operating temperature range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure DB9 Connection:\u003c\/strong\u003e Interchangeable mounting hardware ships with thumbscrews pre-installed and hex nuts included, allowing tool-free or tool-secured attachment to match the mating connector style on any serial device.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"StarTech","offers":[{"title":"Default Title","offer_id":52326758514872,"sku":"1P6FFCN-USB-SERIAL","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/9110\/4952\/files\/1082494366.jpg?v=1764187543","url":"https:\/\/islandelectricalsupply.com\/products\/startech-null-modem-adapter-cable-usb-serial-1p6ffcn","provider":"Island Electrical Supply","version":"1.0","type":"link"}
