Gravity: Active Isolated RS485 to UART Signal Adapter Module

Jargon buster

Plain-language definitions for the technical terms used above.

baud

Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.

RS485

RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.

Short circuit protection

A safety feature that helps protect the device if its output or wiring is accidentally connected in a way that causes excessive current flow. This matters in automation wiring because mistakes or damaged cables can otherwise destroy the sensor or power supply.

UART

UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
