OG_MU-D1-R_v099Fe OPERATION GUIDE Embedded low power radio modem MU-D1-R 915MHz Operation Guide Version 0.99F (Nov. 2010) CIRCUIT DESIGN, INC., 7557-1 Hotaka, Azumino Nagano 399-8303, JAPAN Tel: +81-(0)263-82-1024 Fax: +81-(0)263-82-1016 E-mail: [email protected] Web site: http://www.circuitdesign.jp OG_MU-D1-R_v099Fe Circuit Design, Inc. 4 OPERATION GUIDE T he MU-D1-R is an FCC part15 compliant embedded low power radio modem for transmission of serial data. Since it is possible to control the radio component using dedicated simple commands, the user can concentrate on developing the transmitting and receiving programs for their system. The commands of MU-D1-R are compatible with the commands used for Circuit Design’s MU-1 and MU-2 series. Transmitting and receiving data and issuing commands are performed using a UART* 1 interface with a single-chip C PU and the modem can also be controlled via the COM port (RS232C format) of the computer, making it possible for the user to develop systems quickly* 2 . T he receiving part contains two independent receivers and operates as a true diversity receiver which provides stable receiving performance even in proximity operation prone to multipath effect. The MU-D1-R is designed to minimize design difficulties involving high frequency components, so that the user can embed the modem in their system with peace of mind.
Important It is not possible simply to replace communication using existing RS232C system equipment connected with a cable, with MU-D1-R wireless communication. In order to build wireless systems, issues specific to radio communications must be solved. The hardware and software must be newly designed specifically for the MU-D1-R. *1 UART (Universal Asynchronous Receiver Transmitter) *2 The RS232C interface board with a D-Sub 9-pin connector is available  1.1.1 Features  FCC part15.247 compliant  Command compatible with the MU-1 and MU-2 series  Serial data can be transmitted with a simple system of commands.  Offers a wide communication range with stable operation.  The true diversity receiving system achieves stable communication  The transceiver function is incorporated within a compact unit.  Ideal for battery operated applications thanks to operation at low voltage and low consumption current.  Uses the UART interface commonly available with on-board CPUs.  The high frequency circuit is designed specifically as an embedded radio unit, to operate stably on the user s ystem circuit board.  1:1, 1:N, and N:N systems can be built by flexibly setting link parameters.  It is possible to assess l ocally the status of radio waves and field noise at the source station.  RF power selectable by switching the power amplifier ON/OFF  Using a TCXO in the control part achieves a wide operating temperature range from -20 ºC to 65 ºC  1.1.2 Applications  Serial data transmission Energy monitoring, data monitoring devices, handy terminals, barcode readers, housing equipment control  Telecontrol Various warning systems, remote control for construction machinery, display devices, motor control, lifters Remote control of FA equipment  Telemetry S ecurity systems, water level monitors for rivers and dams, temperature and humidity gauges, rain gauges, pressure gauges, voltmeters, ampere meters Chapter 1 The MU-D1-R 1.1 Outline OG_MU-D1-R_v099Fe Circuit Design, Inc. 6 OPERATION GUIDE The VCC terminal of the MU-D1-R is connected directly to the power source of the mounted CPU. Ensure that the voltage of the power supply is regulated to within DC +4.0 v to +5.0 v. Basically the MU-D1-R uses hardware flow control with RTS or CTS, however 3-line control can be used without the hardware flow control. In this case, set the CTS terminal to Low level. In addition, care is required with the timing of transmitting and receiving. Example 1 and Example 2 are basically the same methods except for the difference in control voltage.  1.3.1 Example 1: Controlling the MU-D1-R with the on-board CPU It is possible to interface the MU-D1-R directly using the UART interface of the on-board CPU.

Using the RS232 port of your computer, you can develop a new program for OS’s such as Windows and the like. In this case, use an RS232C transceiver. (The program for existing system equipment will not work.) 2. By supplying power to the MU-D1-R with a cable, you can also isolate the radio component from your system and locate it in the most suitable environment. The distance can be extended by 15 m to 50 m, but the exact distance should be confirmed through experiments.

The physical crystal and tuning capacitors may be located external to the shielded radio elements. The device is equipped with Metal shielding to cover RF section. Refer to external photos Y 2The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. All inputs to the device are buffered through logic U1 inputs. Refer to Schematic Diagram. Y 3The modular transmitter must have its own power supply regulation. The device is equipped with Internal 2.5VDC and 3.8VDC regulator. Refer to Block Diagram. Y 4The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Device is equipped with unique antenna (part number:Shintake SP060022,verdor:Shintake) or Reverse SMA, or Reverse TNC. Refer to Antenna Specification. Y 5The modular transmitter must be tested in a stand- alone configuration,i.e., the module must not be inside another device during testing for compliance with Part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see Section 15.31(i)). The device was tested outside of the Laptop PC for full modular approval. Refer to setup photos. Y 6The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. (A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. (B) If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. The proposed FCC ID label format is to be placed on the module. If FCC ID is not visible when the module is installed into the system, “Contains FCC ID: V9X-MUD1R” shall be placed on the outside of final host system. Y 7The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Refer to “User’s Guide” ExhibitY 8The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. The device complies with RF exposure compliance requirement Y Alimited modular approvalmay be granted for single or split modular transmitters that do not comply with all of the above requirements,e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation, if the manufacturer can demonstrate by alternative means in the application for equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the operating conditions in which the transmitter will be used. Limited modular approval also may be granted in those instances where compliance with RF exposure rules is demonstrated only for particular product configurations. The applicant for certification must state how control of the end product into which the module will be installed will be maintained such that full compliance of the end product is always ensured.
