TRB141 1-Wire Setup/Configuration

The information on this page is updated in accordance with 00.07.04 firmware version.

Introduction

Inputs and outputs are used for monitoring and controlling a connected device or receiving signals from that device in order to trigger certain events.

1-Wire is a voltage-based digital system that works with two contacts, data and ground, for half-duplex bidirectional communication. Compared to other serial communication systems such as I2C or SPI, 1-Wire devices are designed for use in a momentary contact environment.

In this chapter, we will set up and configure the 1-Wire sensor with TRB141.

Prerequisites

• TRB141
• 1-Wire sensor
• If 1-Wire doesn't have its Wires(Like Dallas DS1820 used in this example) you will need additional wires to connect the sensor to TRB141

Connecting 1-Wire Sensor with TRB141

First of all we will connect the 1-Wire sensor with TRB141, for this example, I will be using two different 1-Wire sensors Dallas DS1820 and Dallas DS1922. Before we proceed with the connection, make sure you know how your 1-Wire sensor has to be connected, or open your 1-Wire sensor data sheet to reference where each wire should be connected.
