Because iButton® products use the company's 1-Wire® protocol, the hardware needed for communicating with an iButton device is inexpensive. All the hardware below lets you communicate with iButton devices from PCs and PDAs to microprocessors and embedded systems.
PC 1-Wire Connectivity
Each receptor contains two Blue Dot connectors to accommodate instances where multiple iButton devices are required for a transaction. A company's policy may, for example, require both an employee and a supervisor to authenticate access to sensitive information stored on a network server.
USB Port Adapters
The DS9490R USB Port Adapter and the DS1402D-DR8 Blue Dot Receptor connect to any standard universal serial bus (USB) port. The DS9490R connects to the USB port and then the DS1402D-DR8 connects to the DS9490 through an RJ-11 connection.
The DS9490 USB Port Adapter comes with the following features:
Serial Port Adapter
The DS9097U RS-232 Serial Port Adapters and the DS1402D-DR8 Blue Dot Receptor connect to any standard RS-232-C serial port. The DS9097U connects to the serial port and then the DS1402D-DR8 connects to the DS9097U through a RJ-11 connection. The DS9097U is not a pass-through device. A serial port must therefore be dedicated to perform iButton communication.
The DS9097U RS-232-C COM Port Adapter comes in three versions:
Parallel Port Adapter
Two other probes are available for communicating with iButton devices through our adapters. The DS9092GT is a Handheld Touch Probe with tactile feedback. It can be connected to either the DS9490R USB port adapter or the DS9097U serial port adapters.
Software Authorization Products
By using an iButton device as the key to lockup your proprietary or licensed software, you can keep unauthorized users from using or copying your software. The following products enable semi-permanent docking of an iButton device to the port adapter for software authorization solutions. Each of these products connects directly to their respective communications port. iButton devices, snap directly into the holder with no additional cables needed.
Embedded Systems Probes and Ports
Many products use iButton devices for access control, data collection or authorization. These devices, such as Door Locks and PDAs, need a 1-Wire probe or port for communicating to iButton devices. For this reason we designed several probes and ports so you can easily build a 1-Wire interface directly to your embedded systems.
The DS9092, DS9092T, and DS9092L are panel-mount Touch Probes pre-wired for easy installation. The DS9092T has tactile feedback for better feel, while the DS9092L is a durable probe essential for outdoor use. The DS9092L also comes with a green LED for directing users where to touch.
The DS9100x parts are for building your own Touch-and-Hold Probe. The DS9100A and DS9100C, the parts used to make the company's DS1402-RP8 and BP8 probes, can be soldered directly to a printed circuit board to create a touch-and-hold probe.
The DS9092R and DS9092RG are 1-Wire Ports designed for communicating to 1-Wire chips or iButton devices within an embedded system. These 1-Wire ports are simply empty iButton 'cans' with data and ground leads inside to allow easy wiring to a microprocessor or 1-Wire micro-LAN. If a product contains 1-Wire chips and/or iButton devices, these ports allow you to communicate with all the 1-Wire devices simply by touching the port with one of the 1-Wire probes described above. Use the RG version for touch-and-hold applications.
iButton devices can be connected to printed circuit boards by using the DS9098P or one of the DS9094 parts. These PCB Mounts come in several different options to fit your needs.
