Introduction to DS9490R

Hello, guys welcome to a new post. We will discuss Introduction to DS9490R. It is USB to single wire configured with the single wire technology designed by Maxim integrated. It is used to configure the one wire output sensor with a computer with the use of a USB port.

It helps for conversion of single wire link to USB through use of USB port assembled on the computer. In this post, we will cover its basic working features and some other points. So let’s get started Introduction to DS9490R.

Table of Contents

DS9490R is an adapter that comes with a high speed of twelve megabytes per second serial interface for the connection of single wire modules to PCs.

This module is configured to Ds2401 which is a sixty-four-bit read-only memory module that has DS2490 USB for a single wire connection.
It is less power-consuming module easy to use with small size devices and used in serial communication.
It also used for intefacing of Button with the personal computer
For handling the one wire to receptacles and different protocols it has a single wire RJ11 interfacing.

DS9490R Features

Its main features are explained here
It is used for interfacing the twelve megabytes per second USB

It is compatible to standard and overdrive single wire protocol
Its slew rate controlled single wire time interval and active pullup for well-equipped single-wire system operation.
It also has compatibility to make a connection with different modules like DS1402D-DR8
It has the ability fo connect single wire to different devices.
It comes with single wire programmable timing to make communication to with other devices.

Applications DS9490R

Its main applications are explained here.
It protects the different software from piracy with the use of button hardware.
Used for different software missions and downloads
It helps to describe the features of iButton and single-wire boards on computers.
It performs the read and write functions.

DS9490R vs. DS9490B

DS9490B is a USB bridge and holder used for a single F5 size iButton. The button is configured with the latched door.
DS9490R is a USB bridge that comes with a 1-wire RJ11 interface for handling 1-wire receptacles and circuits.
For one-wire network cables, define the connectivity matrix table for the DS1402X one-wire system cable. These two adapters are configured on the DS2490 USB-to-1-Wire bridge chip.
DS9490R operated with the DSxx sensor series with the use of a direct connector with DS9490R and operated with a button is not easy to process. DS9490B comes with a certain holder for iButton.
These two modules use 58 58milluiampes for USB active mode and in suspend mode use 0.5 mA.

Applications of DS9490R

The DS9490R is a simple USB module with a one-wire adapter. The one-wire standard is compatible with larger types of sensors and other modules. If these modules are connected with computers, one wire connection is transformed into a USB that is the same as the DS9490R connector has.
While it comes with an RJ11 connection that connects with sensors with the use of a cable.
That RJ11 port is used for the connection of carry of sensors. If needed, the connector to connect with one wire sensor with computers DS9490R is best to use.

What is a DS9490R?

DS490R is a USB module configured to a one-wire system. The one-wire output sensor is configured with a computer through a USB port. That connector transforms one wire connection with a USB connection that is used with a computer USB port.

How to choose a USB adapter?

Maxim made two USB adapters that were used for one-wire EV kits. The DS9490R is a low-cost adapter that operates with five-volt EEPROM one-wire devices and other not-needed certain external programming voltages.
For one-wire devices that work with 3.3 volts, use DS9481R.
There is a 12 V programming pulse used for one-wire EPROM devices for program memory. Applications DS9490R
