CV-USB-RS485 is a USB to RS485\/RS422 adapter designed to bridge serial communication protocols with standard USB interfaces. This adapter allows technicians and AV integrators to connect RS485 or RS422 serial devices directly to a host computer or control system via USB. It is commonly used in professional video conferencing installations where camera control, pan-tilt-zoom commands, or other serial data signals need to pass through a USB-equipped controller or laptop. The CV-USB-RS485 is a compact, single-unit adapter suitable for rack-room deployments and field service work.\u003c\/p\u003e\n\u003cp\u003eThis adapter fits into video conferencing system setups where RS485 or RS422 serial control lines are required. Typical applications include PTZ camera control, serial device configuration, and integration with AV control systems. AV integrators, systems technicians, and video conferencing installers are the primary users. The unit ships individually and is sold as a single piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts USB interface to RS485 and RS422 serial protocols\u003c\/li\u003e\n  \u003cli\u003eEnables serial device control from USB-equipped computers and controllers\u003c\/li\u003e\n  \u003cli\u003eSuitable for PTZ camera control in professional video conferencing environments\u003c\/li\u003e\n  \u003cli\u003eCompact single-unit form factor for field and rack-room use\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit with no minimum order quantity beyond one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a serial communication adapter for use in professional video conferencing and AV control systems requiring RS485 or RS422 serial connectivity over a USB interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed AV integrators or qualified systems technicians. Power down or disable active control signals on the serial bus before connecting or disconnecting the adapter to avoid data errors or device damage. Ensure the correct serial protocol mode (RS485 vs. RS422) is selected in the associated software or control system configuration prior to commissioning. Consult applicable AV system documentation and local codes for structured cabling and low-voltage wiring requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterface\u003c\/strong\u003e: USB to RS485\/RS422\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARSHALL ELECTRONICS INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CV-USB-RS485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARSHALL ELECTRONICS","offers":[{"title":"Default Title","offer_id":51687671497010,"sku":"CV-USB-RS485","price":116.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d90c40d9f4985ca94f4853ec4cc78bc1.jpg?v=1788235521","url":"https:\/\/voomisupply.com\/products\/marshall-electronics-inc-cv-usb-rs485-usb-rs485-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
