RoHS compliant and FCC/CE approved, it’s engineered for reliable industrial and field use without external power supplies.

## Description

USB to RS-485 ConverterIncludesDrivers for Windows 10, 8, 7, Vista, XP, and 2000The 101-0020 USB to RS-485 Converter provides a simple, low cost interface between a PC or laptop with a USB port, and 2-wire RS-485 devices. Universal Serial Bus (USB) drivers make this converter compatible with most software developed for RS-232 serial port interfaces because it appears as an RS-232 port to your software. Switching between receive and transmit is automatically controlled, RTS (request to send) is not needed. Power for the converter is taken from the USB port so no external power supply is required. A rugged design makes 101-0020 an ideal choice for field engineers and technicians who service RS-485 2-wire equipment in an industrial environment. Because the 101-0020 RS-485 converter is used on devices without a ground terminal, voltage suppression is used to clamp the common mode voltage to +/- 7 volts for increased protection.FeaturesAuto transmit control eliminates RTS requirementPower Up/Down glitch-free permits live insertion or removalPowered from USB portCommon mode range permits +/-7V ground differenceNot bus terminated - increases flexibilityRubber and stainless steel enclosure handles rough field useSuper low power design for extended portable computer battery lifeFCC and CE approvedRoHS compliant
