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 ## Features - Auto transmit control eliminates RTS requirement - Power Up/Down glitch-free permits live insertion or removal - Powered from USB port - Common mode range permits +/-7V ground difference - Not bus terminated - increases flexibility - Rubber and stainless steel enclosure handles rough field use - Super low power design for extended portable computer battery life - FCC and CE approved - RoHS compliant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GIJ9WA0 | | Best Sellers Rank | #140 in Serial Adapters #9,959 in Computer Cables & Interconnects | | Brand | Microflex | | Color | Black | | Compatible Devices | Laptop | | Connector Type | USB | | Customer Reviews | 5.0 5.0 out of 5 stars (13) | | Finish | Stainless Steel | | Input Voltage | 7 volts | | Item Dimensions | 0.47 x 0.16 x 0.55 inches | | Item Weight | 4 ounces | | Manufacturer | MICROFLEX | | Mfr Part Number | 101-0020 | | Model Number | 101-0020 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Warranty Type | Extended | ## Product Details - **Brand:** Microflex - **Color:** Black - **Compatible Devices:** Laptop - **Connector Type:** USB - **Item dimensions L x W x H:** 0.47 x 0.16 x 0.55 inches ## Images ![Microflex 101-0020 USB to RS-485 Converter, 1000V Common Mode Range, RoHS Compliant, 20cm Cable - Image 1](https://m.media-amazon.com/images/I/31JcGPI0N0L.jpg) ## Frequently Bought Together - Microflex 101-0020 USB to RS-485 Converter, 1000V Common Mode Range, RoHS Compliant, 20cm Cable - Pepperl + Fuchs VIATOR USB HART Modem Interface with Power Xpress, USB to HART Protocol Modem - VIATOR USB HART Interface --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/29552175-microflex-101-0020-usb-to-rs-485-converter-1000v-common](https://www.desertcart.com.br/products/29552175-microflex-101-0020-usb-to-rs-485-converter-1000v-common) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-12*
