  • Page 11: Introduction

    Introduction The RIM 802D Radio Modem set a new standard for radio modem performance in key areas, such as 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 12: Radio Performance

    The RIM 802D Radio Modem offers high performance on DataTAC networks. Receiver sensitivity The RIM 802D Radio Modem has a receiver sensitivity of –118 decibel milliwatts (dBm) using the MDC over-the-air protocol, and –111 dBm using RD-LAP, at a 0.05 packet error rate (BER).
  • Page 13 Introduction Powerful and efficient transmitter The RIM 802D Radio Modem is designed to supply a full 2.0 watts to the antenna. RIM radio modems provide reliable, efficient transmission across the entire operating voltage range of 4.1 to 4.75 volts. Batteries can be used even when they are almost depleted, which maximizes the radio coverage area throughout the life of the battery.

  • Page 14: Datatac Network Technology

    Small size Using a single-board design, the RIM 802D Radio Modem is very thin, and smaller than a business card. It measures 1.65 by 2.66 inches (42.0 by 67.5 mm). This small size allows the radio modem to meet tight space requirements within most applications.

  • Page 22: Test Board Overview

    The RIM test board provides a standard RS-232 serial interface between a computer and the radio modem. The test board helps you interface the RIM 802D Radio Modem to a standard computer using a COM port, or to a terminal device using a RS-232 serial port.

  • Page 23: Connecting The Test Board

    Connecting the test board You must connect the RIM 802D Radio Modem to an antenna and to a computer, or some other device with a RS-232 serial interface. Use the test board and cables supplied with your Integrator’s Kit.
  • Page 24 5. Turn on the system 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 ON. It is lit when the radio is on.

  • Page 25: Using The Menu Tool

    Getting started Using the MENU tool The RIM 802D Radio Modem contains a diagnostic utility called MENU. This utility enables you to set the current network, send test messages to the radio modem, and monitor radio and network status. The MENU utility is embedded in the radio modem firmware.
  • Page 26 If you continue to have problems, verify that the radio is turned on and connected to the computer, and that all cables are connected securely. Contact RIM for assistance if you are unable to continue at this point. The MENU screen displays the software version, the radio modem serial number, a list of available wireless networks, a list of setup commands, and status indicators.

  • Page 33 Mechanical integration Mounting methods RIM radio modems can be fastened securely using a variety of methods. You must consider the operating environment when choosing a mounting option. For example, extreme temperature, heavy vibration, or high electromagnetic interference areas can require a special mounting solution. You must ensure that the radio modem remains securely attached in the environment where it is used.

  • Page 50: Automotive Supplies

    Power requirements Automotive supplies If you plan to power the RIM 802D Radio Modem from an automotive supply, special steps must be taken to protect the radio modem from intense power fluctuations experienced when an automobile is started. A circuit comprising inductors, transorbs and voltage regulators should be used to ensure that the radio modem is protected from these power fluctuations.

    (RAP). If you are using a NCL application with another DataTAC radio and are now migrating to the RIM 802D, you do not need to rewrite the application in RAP. You can continue using the existing NCL application. If you are writing a new application for the RIM 802D Radio Modem, you must choose whether to use NCL or RAP as your link-layer protocol.
  • Page 52 NCL is designed to be robust and redundant, and should be used when the serial link is unreliable or when the serial cable to the RIM 802D radio modem is very long. However, advances in mobile computing technology have helped to ensure that serial links are short enough to make bit errors extremely unlikely.

  • Page 62: How To Turn The Radio On And Off

    Turning on the radio To turn the RIM 802D radio modem 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 modem to shut down, and the radio is performing shutdown operations and should not be disturbed.
  • Page 63 Note that if any line is left in the high state, as much as 5 mA may flow into the radio modem. Data that has been received by the RIM 802D radio modem from the DataTAC network, but has not been transferred to the computing device, will not be saved.

  • Page 67: Antenna Selection

    The antenna is one of the most important components of a wireless communication system. The right antenna will maximize the coverage area of the RIM radio modem. The antenna that you choose should complement the needs of your specific project. There are many different antenna types and options that will meet your engineering and user requirements while remaining within budget constraints.

    VHF and UHF has led to the use of a half-wave dipole as the reference element. At the antenna port, the output power of the RIM 802D is 2.0 W The antenna gain (or loss) will result in an increase (or decrease) in the output power.
  • Page 70 The antenna, cables, and connectors in a radio frequency system must all possess the same impedance. The impedance required by the RIM 802D radio modems is 50 Ω, which is a widely-available industry standard. Any deviation from this value may result in impedance mismatch and signal loss.
