Quick Start

To download the 1-Wire drivers software package, visit

the

1-Wire Drivers page and click the button that takes

you to the

Download Page. Select the applicable ver-

sion of the Windows operating system and select the file

that corresponds to your PC’s configuration (e.g., 32-bit

1-Wire drivers or 64-bit 1-Wire drivers) and then click the

Download button. The web page provides assistance

on how to detect whether your PC runs a 32-bit or 64-bit

operating system.

1) Double click on the file you just downloaded

(

install_1_wire_drivers_x64_v405.msi or newer).

2) Select

Run when prompted with the question “Do

you want to run or save this file?”

3) The welcome setup wizard box opens for the One-

WireDrivers Setup. Click the

Next button.

4) Read and check the box if you accept the license

agreement. Click

Next.

5) Leave the destination folder to default and click

device software?” click

Install.

7) Click the

Finish button to exit the Setup Wizard.

8) After running the 1-Wire installation wizard, make

sure internet is available and plug the DS9490R USB

adapter in to a free USB port in your PC.

9) Plug the RJ-11 Modular connector of the DS1402D-

DR8 Blue Dot Receptor into the DS9490R USB

adapter.

10) Optionally snap the iButton into the key fob. This

makes easier removal of the iButton from the Blue

Dot Receptor.

key fob in warm water prior to inserting the iButton.

The warm moisture helps the key fob slide on easier

to the iButton.

All Programs and select

the folder 1-Wire Drivers x64. Select the

Default

1-Wire Net.exe program. When the program window

tions for missioning and reading the contents of a
