I've purchased two iButton kits and some other iButton stuff. Here are the
prices and contents:
- The iButton Starter Kit (DS9092K, revision 4.0A, 5/15/97)
Ordered May 1998 for $75.00 plus tax from Dallas (1-800-336-6933).
- 1x DS1920-F5 temperature button
- 2x DS1971-F5 256-bit EEPROM button
- 4x DS1982-F5 1kbit "add-only" button
- 1x DS1994L-F5 4kbit NVRAM plus time button
- 1x DS1996L-F5 64kbit NVRAM button
- 1x DS9097E "passive" serial-port adapter (DB25M to RJ11 socket).
"EPROM Upgraded", meaning it has a socket for an external DC power
supply which can be used to program EPROM buttons (maybe the 1982?
or the 1971? I'm not sure).
- 1x DS9092GT hand-held wand thingy, cable with RJ11 plug
- 1x DS1402BR RJ11 plug on one end, fake iButton on other to plug
- 1x DS1401 4-socket iButton bus, just 4 ibutton sockets tied
- assorted mounting hardware, plastic holders, key fobs, hospital
bracelets, sticky discs, badges
- DS9092K User's Manual, Book of DS19xx iButton Standards,
50 Ways To Touch Memory, Automatic Identification Data Book.
- The JavaButton Kit (DSJTK-001 Version 1.0)
Ordered July 1998 for $50.00 plus tax from Dallas
- 1x Java Button on a permanently-mounted angled plastic key fob.
- 1x DS9097U "active" serial-port adapter (DB9F to RJ11 socket).
Contains a DS2480 interface chip and (surprise) a DS1982 equivalent
solder-mount device internally attached to the one-wire bus. I
don't know why.
- 1x DS1420D-DR8 "Blue Dot Receptor". Has an RJ11 plug at one end,
the other has a pair of sockets with a blue plastic thingy in the
middle where you can stick an iButton. The DS9097U+DS1420D-DR8
combo is available for $15 separately.
- 1x piece of paper "Software Authorization Customer Registration
Form" with instructions to download the software from
- 1x exciting full-color brochure "Digital Accessories that Fit
- um, that's it.
- The DS1411
- DS1411 has the DS2480 "active" serial interface chip inside a
DB9F dongle-shaped serial port plug. It has a cavity that just
fits a single iButton (using a DS9098 "MicroCan Retainer" socket
listed in the iButton data book). See the
for a picture. It is meant as a dongle, once you put an iButton in
the socket you could put a sticker over the whole thing and you'd
never know what was inside it. The DS1411 has (surprise) a DS1990A
equivalent (id-only) hidden somewhere inside it, soldered down to
the circuit board, so you could basically use it as a dongle even
without adding a real iButton, if you didn't mind clever people
writing microcontroller programs to spoof the one-wire protocol
and replace the dongle. Keep the extra device in mind when trying
to use the 'Read ROM' command: if you have a button in place, the
two devices will conflict and the Read ROM checksum will fail. Use
Search ROM instead. I find this interface handy to use with my
laptop. There is a development kit on the Dallas FTP site for the
DS1411, that emphasizes the "software authorization control"
uses. Decent code.
- The DS1820-PR35
This is the solder-mount version of the DS1920 temperature iButton.
It looks like a TO-92: a slightly-tall three-terminal plastic transistor
case. One pin is ground, one is data, the third is an optional extra
Vcc that could be useful if your One-Wire Bus driver can't supply the
strong-pullup during the temperature conversion cycle.
There is a price list for
see it. There are prices for the basic memory iButtons ($2.30 for single
DS1990A id-only buttons, $12 for single 4kNVRAM buttons). It has some
adapters, some goofy button holder stuff, and some nebulously-defined "kits"
with unspecified contents. Call Dallas and ask them what's in the kits before
you buy them. (and tell me so I can put more information here).
ftp://ftp.dalsemi.com/pub/ has some
downloadable software. Of note:
