Limited Hardware Warranty.
RF Monolithics, Inc. (“RFM”) warrants solely to the purchaser that the
hardware components of the DR2000 Virtual Wire® Development Kit (the “Kit”) will be free from
defects in materials and workmanship under normal use for a period of 90 days from the date of
shipment by RFM. This limited warranty does not extend to any components which have been
subjected to misuse, neglect, accident, or improper installation or application. RFM’s entire liability
and the purchaser’s sole and exclusive remedy for the breach of this Limited Hardware Warranty
shall be, at RFM’s option, when accompanied by a valid receipt, either (i) repair or replacement of
the defective components or (ii) upon return of the defective Kit, refund of the purchase price paid for
the Kit.
EXCEPT FOR THE LIMITED HARDWARE WARRANTY SET FORTH ABOVE, RFM AND
ITS LICENSORS PROVIDE THE HARDWARE ON AN “AS IS” BASIS, AND WITHOUT
WARRANTY OF ANY KIND EITHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING BUT
NOT LIMITED TO THE IMPLIED WARRANTIES OF NONINFRINGEMENT, MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE.
Some states do not allow the exclusion of implied
warranties, so the above exclusion may not apply to you. This warranty gives you specific legal rights
and you may also have other rights which vary from state to state.
Limitation of Liability. IN NO EVENT SHALL RFM OR ITS SUPPLIERS BE LIABLE FOR ANY
DAMAGES (WHETHER SPECIAL, INCIDENTAL, CONSEQUENTIAL OR OTHERWISE) IN
EXCESS OF THE PRICE ACTUALLY PAID BY YOU TO RFM FOR THE KIT, REGARDLESS OF
UNDER WHAT LEGAL THEORY, TORT, OR CONTRACT SUCH DAMAGES MAY BE ALLEGED
(INCLUDING, WITHOUT LIMITATION, ANY CLAIMS, DAMAGES, OR LIABILITIES FOR LOSS
OF BUSINESS PROFITS, BUSINESS INTERRUPTION, LOSS OF BUSINESS INFORMATION,
OR FOR INJURY TO PERSON OR PROPERTY) ARISING OUT OF THE USE OR INABILITY TO
USE THE KIT, EVEN IF RFM HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
BECAUSE SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF LIABILITY
FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES, THE ABOVE LIMITATION MAY NOT
APPLY TO YOU.
Special notice on restricted use of DR2000 Virtual Wire®
®
Development Kits
DR2000 Virtual Wire® Development Kits are intended for use solely by professional engineers for
the purpose of evaluating the feasibility of low-power wireless data communications applications.
The user’s evaluation must be limited to use of an assembled Kit within a laboratory setting which
provides for adequate shielding of RF emission which might be caused by operation of the Kit
following assembly. In field testing, the assembled device must not be operated in a residential
2
area or any area where radio devices might be subject to harmful electrical interference. This Kit
has not been certified for use by the FCC in accord with Part 15, or to ETSI I-ETS 300 220 or
I-ETS 300 220-1 regulations, or other known standards of operation governing radio emissions.
Distribution and sale of the Kit is intended solely for use in future development of devices which
may be subject to FCC regulation, or other authorities governing radio emission. This Kit may not
be resold by users for any purpose. Accordingly, operation of the Kit in the development of future
devices is deemed within the discretion of the user and the user shall have all responsibility for
any compliance with any FCC regulation or other authority governing radio emission of such
development or use, including without limitation reducing electrical interference to legally
acceptable levels. All products developed by user must be approved by the FCC or other authority
governing radio emission prior to marketing or sale of such products and user bears all
responsibility for obtaining the FCC’s prior approval, or approval as needed from any other
authority governing radio emission.
If user has obtained the Kit for any purpose not identified above, including all conditions of
assembly and use, user should return Kit to RF Monolithics, Inc. immediately.
The Kit is an experimental device, and RFM makes no representation with respect to the
adequacy of the Kit in developing low-power wireless data communications applications or
systems, nor for the adequacy of such design or result. RFM does not and cannot warrant that the
functioning of the Kit will be uninterrupted or error-free.
The Kit and products based on the technology in the Kit operate on shared radio channels. Radio
interference can occur in any place at any time, and thus the communications link may not be
absolutely reliable. Products using Virtual Wire® technology must be designed so that a loss of
communications due to radio interference or otherwise will not endanger either people or property,
and will not cause the loss of valuable data. RFM assumes no liability for the performance of
products which are designed or created using the Kit.
RFM products are not suitable for use in
life-support applications, biological hazard applications, nuclear control applications, or
radioactive areas.

1.0 DR2000 Virtual Wire® Development Kit Introduction
1.1 Purpose of the DR2000 Virtual Wire® Development Kit
®
The DR2000 Virtual Wire® Development Kit is a tool for evaluating the feasibility
of a low-power wireless data communications application. The kit also facilitates
the development of the actual system.
1.2 Intended Kit User
The DR2000 Virtual Wire® Development Kit is intended for use by a professional
engineer with a working knowledge of data communications. The kit itself is not
intended as an end product, or for use by individuals that do not have a
professional background in data communications. Please refer to the Special
Notices section in the front of this manual.
1.3 General Description
The DR2000 Virtual Wire® Development Kit allows the user to implement low-
power wireless communications based on half-duplex packet transmissions. The
kit contains the hardware and software needed to establish a wireless link
between two computers with RS232C serial ports. The kit includes two
communications nodes, with each node consisting of a data radio protocol
board, plus accessories. The DR2000-DK kit operates at 916.5 MHz.
