    This symbol represents a hint or a suggestion. Although the ideas presented are not necessary to the integration of the RIM 801D, they are useful to many applications, and they may save integrators time.

  • Page 11: Introduction

    Introduction Topics covered in this introduction include the RIM 801D OEM radio modem features and an introduction to DataTAC network technology. Radio modem features The RIM 801D OEM radio modem is specifically designed to integrate easily into a computer or other embedded system, such as PDAs, vending machines, and point-of-sale terminals.
  • Page 12 Using a single board design, the RIM 801D is very thin, only 0.3” to 0.38” (7.5 to 9.6 mm). The RIM 801D is about the size of a credit card, with a footprint of 3.5” by 2.6” (87.5 by 66.3 mm). This tiny size makes the RIM 801D very lightweight (only 2.3oz or 64g, including case) and allows the...

    Mechanical specifications and mounting needs This chapter provides information about the RIM 801D that will be useful in determining the physical positioning of the radio modem within an application. Environmental properties, case dimensions, cabling, connectors, and mounting suggestions are presented.

  • Page 16: Physical Properties

    Physical properties Dimensions The RIM 801D has been designed to meet the most stringent space requirements. In most cases, there will be sufficient room in an existing enclosure to house the radio modem. Within the case of the modem, the smaller components are mounted on one side, and the larger components on the other.

  • Page 18: Mounting The Rim 801D

    The designer should select an adhesive based on its suitability to the mounting surface of the radio modem as well as the casing. The outer casing of the RIM 801D is pre-tinned steel or stainless steel, with a thickness of 0.010” (0.25 mm).
  • Page 19 Appendix II for complete contact information. Reclosable Fasteners A reclosable fastener may be used to affix the RIM 801D to a surface. The use of such fasteners is useful if the radio modem might be removed at some point during the product’s life. For example, the RIM 801D can be installed in a housing with no need for the end user to remove the radio modem, but the product manufacturer might later wish to do so.

  • Page 21: Power Requirements

    Power requirements The RIM 801D OEM Radio Modem must be provided with a clean, high current power source. This can be provided by a plug-in power supply unit, a rechargeable battery pack, or single use batteries. RIM has conducted extensive research and has developed guidelines for integrators to follow when designing the power supply system for the RIM 801D OEM Radio Modem.

  • Page 23: Automotive Supplies

    Power requirements: Automotive supplies Automotive supplies If you plan to power the RIM 801D from an automotive supply, extra protection must be included to protect the radio modem from the intense power fluctuations experienced when the automobile is started. A circuit comprising inductors, transorbs and voltage regulators should be used to ensure the radio modem is protected from these power fluctuations.

  • Page 24: Single Use Batteries

    Power requirements: Single use batteries Single use batteries When using single use cells, RIM has found that only Alkaline cells provide the high current necessary for transmission. AA, AAA, and even square 9 Volt batteries provide an excellent power source. The following graph was generated by a simulator, not an actual radio modem;...

    8 volts DC to operate the RIM 801D, as well as 5 volts for the embedded system VCC. Please note that it is not necessary to supply the RIM 801D with a 5 volt VCC — there is only one power source to the radio modem, and that is the 8 volt supply.

  • Page 26: Connecting The Power Source

    Power requirements: Connecting the power source Transient voltage protection zener diodes, or other spike arrestor circuits, should also be added to keep the inputs within the limits given in the RIM 801D load specifications. These should have a value of 20 volts and be placed on the supply side of the regulator circuit.

  • Page 27: Serial Interface Specification

    Serial interface specification The serial interface on the RIM 801D operates at HCMOS electrical levels. This interface can be connected directly to a micro-controller, or through a UART to a microprocessor data bus. Signal specifications (Standard 5V interface) Outputs 4.5 Volts Min.

  • Page 28: Connecting The Serial Cable

    The RIM 801D can also be customized for 3.3 volts. Connecting the serial cable The RIM 801D serial communication and power on/off signals are carried on a flat 14-conductor flexible printed circuit (FPC) cable, which can plug into a matching connector.

  • Page 29: Detailed Pin Description

    DNC1 and DNC2 These are “Do Not Connect” pins. They are used for internal testing of the Radio hardware by RIM. Connecting these pins to VCC or Ground can damage the radio. Simply leave these pins disconnected when integrating the radio modem into your device.

  • Page 33: Turning The Radio On

    Serial interface specification: Turning the radio ON Turning the radio ON To turn on the RIM 801D, the software should first check the ONI pin. If ONI is high, but TURNON is being held low, then the radio is currently performing shutdown operations and should not be disturbed.

    Turnoff are not connected to the RIM 801D radio modem, but to the processor of the embedded system. If no processor is present, the Turnoff line can be tied to the RIM 801D’s Turnon, and the Shutdown signal can be tied to the RIM 801D’s ONI line.

  • Page 35: Antenna Integration

    Antenna integration The choice of antenna is important to maximizing the coverage area of the RIM 801D radio modem. It is important to choose an antenna that will best compliment the needs of a specific project. There are many different antenna options that will meet both your gain and directivity requirements and remain within budget constraints.

  • Page 36: Equation 1: Vswr

    Equation 2: Return Loss The antenna match for “best performance” is a VSWR ≤ 1.5 or a RL < -14 The antenna match which is the minimum acceptable for the RIM 801D is a VSWR ≤ 2.0 or a RL < -10 dB.

  • Page 40: Shielding

    The RIM 801D is designed to provide high immunity to RF noise; consequently, it will not be necessary to provide special shielding. In fact, it is more important that the power supply to the RIM 801D be free of high- Integrator’s Guide – RIM 801D OEM Radio Modem...
  • Page 41 RF shielding between other computing devices and the RIM 801D case. The RIM 801D case provides shielding to prevent it from being affected by RF interference from the computing device to which it is attached. The case also prevents the RIM 801D from emitting RF energy into the computing device and disrupting the computing device’s operation.

  • Page 43: Protocol Support

    RAP offers several advantages over NCL when used with the RIM 801D, or other applications where the radio modem is physically located close to the host device. RAP is a scaleable protocol that is easy to implement, it uses only 1 to 3 K of program storage.

    RIM 801D over an asynchronous serial port, using RAP’s framed link protocol. The RAP program is not concerned with the transfer of data between the RIM 801D and a DataTAC network base station, as the RIM 801D completely handles transmission and reception.
  • Page 46 Kbytes. This increases the memory available for applications. The RIM 801D OEM radio modem includes on-board support for both NCL and RAP. Even when in RAP mode, the RIM 801D can detect certain NCL frames arriving on the serial port. This will cause the radio to automatically switch to NCL mode.
  • Page 47 The header consists of a unique sequence of values (0x9D, 0xAE, 0xBF). This signals the beginning of a RAP frame to the RIM 801D radio modem. The frame type indicates which one of the 18 different RAP frame types is being used.
