  • Page 9: Introduction

    Introduction With the introduction of the RIM 802D, Research In Motion (RIM) has set a new standard for radio modem performance. The RIM 802D is unrivaled in the key areas of receiver sensitivity, output efficiency, noise immunity, and power consumption. Its small size and weight make it suitable for virtually any wireless data application, including handheld devices and mobile terminals.
  • Page 10 RF shielding Low power requirements If you are planning to integrate the RIM 802D into a handheld or portable device, battery life is a critical issue: your customers will insist on long lasting devices without heavy battery packs. The RIM 802D sets a new power consumption standard for DataTAC radio modems.
  • Page 11 Using a single board design, the RIM 802D is very thin, and much smaller than a business card, at only 42.0 by 67.5 mm. This tiny size allows the RIM 802D to meet tight space requirements within most applications. Its single-board...

  • Page 15: Getting Started

    Years of intense R&D have spawned several tools that have been used internally to help streamline our own development process. We have included many of these tools with the RIM 802D OEM Developer’s Kit. The purpose of the Kit is to accelerate radio integration and to help system designers evaluate the RIM 802D.

  • Page 16: Test Board Overview

    It is designed to help you quickly interface the RIM 802D to a standard PC (through a COM port) or a terminal device with an RS-232 serial port. The test board also provides access points to the radio’s communication port, which allows you to monitor activity with a logic probe, multimeter, or oscilloscope.

  • Page 17: How To Connect The Test Board

    Now that you are familiar with the components and functions of the test board, you are ready to connect the RIM 802D radio modem to an antenna and to a PC (or some other computing device with an RS-232 serial interface). To do this, you will use the test board and cables supplied with your RIM 802D Developer’s Kit.

  • Page 18: The Menu Diagnostics Tool

    The power switch on the test board is connected to the TURNON line of the RIM 802D radio modem. To determine whether the radio is on, look at the LED marked ONI. It is lit when the radio is on.
  • Page 19 Setup The following instructions assume that your RIM 802D is connected to a PC running a terminal program, such as Windows HyperTerminal. The MENU utility is based in the RIM 802D’s firmware, so HyperTerminal is the only software required to use it.

    Power supply parameters The RIM 802D requires a clean, stable 4.1 to 4.75 volt source that is capable of delivering a one-second burst of up to 1.7 A when required by the transmitter.
  • Page 36 A passive LC (series L, shunt C) power filter can be put between your power supply and the RIM 802D radio modem to reduce ripple at the radio connector. Bear in mind that the RIM 802D radio already has about 70 F of on-board shunt capacitance.

Calculating overall power consumption The instantaneous power consumption varies between 0.2 mA and 1.7 A, a range of four orders of magnitude.

  • Page 38: Batteries

    The selected cells must be able to meet the load specifications of the RIM 802D. Specifically, they must be able to provide 1.7 A (at 4.4 V) for transmission. Rechargeable cells vary considerably, because capacity varies with current draw.

Note that pins 9 through 22 on the RIM 802D correspond to pins 14 through 1 on the RIM 900. The numbering is reversed because the connector is reversed, but physically the leftmost pin on the RIM 802D connector is the same as the leftmost pin on the RIM 900 connector.

This output from the radio that is asserted while the RIM 802D is transmitting a packet to the network base station. TRI has a built-in current limiter that allows it to drive an LED directly, to provide real-time visual feedback to the user that the radio is transmitting packets.
  • Page 46 When this line is high, any data sent from the computing device to the RIM 802D may be lost. This is a flow control mechanism that is normally reacted to by the UART in your serial communication system.
  • Page 47 The active (data terminal ready) state of this line is low, and indicates that the computing device is ready to receive data from the RIM 802D. De-asserting this line high will turn communication off; the RIM 802D would not attempt to deliver data to the computing device until ~DTR is again asserted low.

  • Page 48: How To Turn The Radio On And Off

    Turning the radio on To turn the RIM 802D on, the software should first check the ONI pin. If ONI is high, but TURNON is being held low, then your application has recently requested the radio to shut down, and the radio is performing shutdown operations and should not be disturbed.
