`
`Because iButtons use the 1-Wire protocol, the hardware needed for communicating with
`an iButton is inexpensive. Any PC, PDA or other computing device with the necessary
`ports and software can easily communicate to any iButton through our 1-Wire port
`adapters.
`
`PC 1-Wire Connectivity
`The DS1402D Blue Dot Receptors are
`iButton reader/probes that provide a
`convenient pipeline into the PC for iButton-
`to-PC communication. The receptor's cable
`connects to a USB, serial, or parallel-port
`1-Wire adapter, whichever type of port you
`wish to use. The receptor itself easily
`affixes to any accessible spot on the front
`of the PC. The user can elect a quick
`information transfer with a momentary
`touch of the iButton to the Blue Dot. For
`hands-free operation the iButton can be
`snapped into the Blue Dot and remain
`there.
`
`Each receptor contains two Blue Dots to accommodate instances where multiple iButtons
`are required for a transaction. A company's policy may, for example, require both an
`employee and a supervisor to authenticate access to sensitive data stored on a network
`server.
`
`Several adapters are available that actually hold iButtons. Each adapter/iButton
`combination becomes a self-contained security device perfect for software authorization
`solutions.
`
`USB Port Adapters
`We offer two 1-Wire USB Port Adapters, the DS9490R and the DS9490B, both of which
`connect to any standard universal serial bus (USB) port. The DS9490R is designed to
`connect multiple 1-Wire/iButton devices to a PC or handheld through its RJ-11 connector.
`Attaching the DS1402D-DR8 Blue Dot Receptor to the RJ-11 connector is a popular way
`to interface a PC to a 1-Wire network comprised of multiple iButtons.
`
`The DS9490B, in contrast, is designed to hold a single iButton, perfect for software
`authorization solutions. The DS9490 family of 1-Wire USB port adapters comes with the
`following features:
`• DS9490R
`◦ USB port
`◦ Internal 64-bit address
`◦ Communicates to all iButtons; can read but not write to
`DS198x EPROM iButtons

`◦ RJ-11 out; compatible with DS1402D-DR8 Blue Dot Receptor
`
`• DS9490B
`◦ USB port
`◦ Internal 64-bit address
`◦ Single iButton holder
`◦ Can be used as a key-chain fob
`◦ Ideal choice for software authorization solutions
`
`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:
`• DS9097U-S09
`◦ 9-Pin RS-232-C port
`◦ Communicates with all iButton devices, can read but not write
`to DS198x EPROM iButton devices
`• DS9097U-009
`◦ 9-Pin RS-232-C port
`◦ Has internal 64-bit address
`◦ Communicates with all iButton devices, can read but not write
`to DS198x EPROM iButton devices
`
`Please note that other serial-port adapters are available, including some that can
`physically hold an iButton. These adapters are perfect for software authorization solutions.
`We also offer passive serial-port adapters for legacy systems. To examine our complete
`line of serial-port adapters, please visit the associated parametric tables.
