Description USB to RS485 - 3 Pin Running MODBUS/RTU over an RS485 network is pretty cool, in an old-school way. The technique was invented decades ago, and allowed you to connect to a few dozen MODBUS devices over simple twisted pair copper wire, over a thousand feet distance or more. It's such a successful technique that it has not been supplanted by new modern communication technologies like TCP/IP. Unfortunately most modern computers do not have RS-485 interfaces. Fortunately there are many USB-RS485 adapters available. RS485 to TTL Module is for long range, high data rate error prone differential communication. Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications. Quick Spec Standard: USB2.0 standard, backward compatible, in line with the standard RS485 Direction control: the use of automatic data flow control, auto distinguish and control data transfer direction Baud Rate: 300-9216000bps, automatically detecting the serial signal data rate Load capacity: support multipoint, each converter allows RS485 interface device to connect 32 Interface Protection: TVS tube protection, USB self-recovery protection Self-powered from USB Using virtual serial COM port Support Windows98 / ME / 2000 / XP / WIN7 / Vista / Linux / Mac Dimensions: 76 x 18.5 x 16mm Resources Datasheet Shipping List 1 X USB to RS485 - 3 Pin More Products View More Products
