Overview
The DM-15 module is intended for mounting into an application developer’s chassis to provide wireless
communication capability for the product. The target chassis could be in a wide variety of forms such as a
residential electric meter, a point of sale terminal, an alarm panel, or an automobile console. All initial
configuration, mode control, and operational commands are issued to the module over an RS-232 serial port
using a flexible AT command format. The module circuitry has been designed to meet the environmental
requirements of a large range of commercial and industrial users.
1.1
General
DM-15 is a fully RF shielded PCB assembly with dimensions of approximately 4 x 2 x .7 inches. It has three
external interfaces: a 30-pin system connector, a 16-pin accessory connector and a miniature coaxial RF
antenna connector.
Figure 1.1 -1: DM-15 Module
1.2
Operating Modes
The word “mode”, when applied to DM-15 can refer to either software modes or hardware modes. Desired
usage can be determined from the context. Software modes are the various ways in which DM-15 can be made
to send and receive wireless data. They are described briefly in Section 1.3 below. Hardware modes are the
various ways in which the functions of the 30-pin connector can be changed as needed for testing or to
configure DM-15 for different applications. Hardware modes are described in more detail in Section 2.
1.3
Software
DM-15 software options can be used to configure the module hardware to operate in a wide variety of cellular
voice and data communication modes. The first two software option packages to be delivered for the module
are described below.
1.
IS-136 rev. B with IS-130/IS-135 asynchronous data and group 3 fax capability - This software provides
dual mode AMPS/ TDMA cellular communications over the 800 MHz cellular frequency band. The
module automatically switches between the legacy AMPS system and the newer digital IS-136 cellular
system based on system availability and/or manual selection by the host application.
2.
AMPS 553 analog voice with burst data capability – This software option is being offered in response to a
need for a voice/data communications capability with high percentage geographical coverage over most of
the United States and Canada. The AMPS cellular system using circuit switched data is the only viable
option at this time. Although digital cellular systems with data capability are being deployed in several
locations around the county, it will be many years if ever before they have the coverage footprint of the
existing AMPS system. In addition to providing voice communication services, this software option
provides a built-in circuit switched burst data modem over the analog circuit switched cellular network.
V.27ter is used to transmit the data, which is heavily encoded to combat the fading in the mobile
environment. The burst data is operated in a half duplex mode. The module is capable of transmitting or
receiving 250 bytes of data over the analog circuit switched cellular network in less than 5 seconds. The
DTMF tones are used to switch between voice and data modes either locally, or by a remote
communication center.
All of the software platforms listed above include a serial bus multiplexing protocol capability that can be used
by the application developer to create multiple virtual communication channels with the DM-15 module over
the single serial port. A common example of the virtual channel application is providing simultaneous transport
of mode commands, data traffic, and status messages between the module and the main application control
microprocessor.
1.4
Hardware
The next two sections give a top-level overview of DM-15 as seen from the application developer’s
perspective. Hardware design details inside the DM-15 module are described in the “DM-15 Operational
Description”.
1.4.1 Mechanical
The DM-15 module has no mechanical elements other that the main PCB assembly. All critical electronic
components are shielded using sheet metal cans to prevent internal/external electromagnetic interference from
degrading the module’s performance and to prevent the module from interfering with other nearby devices.
Figure 1.4-1 shows a typical mounting configuration of the module with the main motherboard assembly. The
module is plugged into the fixed mating connector and secured with four screws to the standoff components.

Antenna Connector
Radio frequency (RF) signals from the module to the external, customer-supplied antenna are made
through a surface mount, microminiature snap-on M/A-COM connector (P/N 2367-5002-54). A wide
variety of compatible mating connectors are available. Pigtail assembly (P/N 9960-2100-24), and the
inter-series cable assembly (P/N 9960-4100-XX) from M/A-COM are two options using preassembled cables. The cost of these cables varies with quantity and connector type. Another mating
option is a right angle crimp jack from M/A-COM that uses standard RG-type coaxial cable. Custom
cables assemblies can be then be manufactured to individual requirements using standard off-the-shelf
coaxial cable and mating connectors (TNC, SMA, etc.) with

Right Angle Crimp Jack
either RG-178 (P/N 2338-5001-10) or RG-316 (P/N 2338-5002-10) size M/A-COM connectors. The
cost of the crimp connector alone is approximately $1.50 USD in quantities of 10,000. Physical
dimensions of the two module connector types are shown above. Since the mating connector can
rotate through 360o, the application developer has maximum flexibility for routing the RF coax
assembly. The total height of the mated pair using M/A-COM pre-assembled RF connectors is 0.12
inches. The mated pair height using the right angle crimp jack is approximately 0.290 inches.
2.3
Electrical Performance
Electrical performance parameters are valid only when the terminating impedance at the output of the
antenna connector exhibits a VSWR of less than 2:1 for all phase angles in the frequency band of
operation. High VSWR loads at the antenna connector adversely affect current consumption,
linearity, and power efficiency of the module and may prevent operation or cause internal damage.
The RF performance of the DM-15 fully meets the following specifications:
• IS-136 TDMA Cellular mode – Per IS-137 specification
• 553 AMPS Cellular mode – Per IS-19 specification
2.4
Mobile Station Power Class
The module is able to operate in several modes and different output power levels. Typical
applications require output power levels similar to those in a handheld cellular phone (600 mW
nominal) which is considered a power class IV unit for dual mode operation. It is possible to increase
the output power level to that of a class I unit (4 W nominal) during the 5 second analog burst data
ode. Table 2.4-1 below shows the nominal output power levels (Effective Radiated Power, assuming
an antenna system gain of 1 dBd (2.5 dBd antenna gain with 1.5 dB cable loss)).

A power down or "sleep mode" is available in which the module is placed in a low power
consumption state under control of the host application. In this mode, the unit consumes
approximately 35 uA of current as measured from the VCC_5V supply input on pin 1 of the system
connector. A logic level "0" on pin 19 of the system connector returns the unit to full operation
although there may be a significant delay while the module reestablishes registration with the cellular
network

External Control/Interface
3.1
Introduction
DM-15 interfaces with external controlling devices via an RS-232 serial port on the 30-pin system
connector. This section defines the interface protocol between the controlling device and DM-15 over the
serial port. Future versions of this document will also include the interface definition between various
external accessories and DM-15 over the accessory connector.
The primary message transport mechanism across the system connector interface uses the AT command
format. However, other transport mechanisms, for example, a packet protocol based messaging
mechanism, may also be supported per customer specifications.
Information about AT commands and responses for various Ericsson products are available in two
formats: (1) AT Command Ensembles, and (2) Product Design Documents. An “AT Command
Ensemble” is a group of AT commands that have a specific purpose such as factory test, mode control,
phonebook management, etc. Product Design Documents specify the subsets of AT commands in
various ensembles applicable to a particular product. A separate “Product Design Document” will be
generated for each product.
The AT command descriptions included in this document are intended only to give an overview of the
command functions available, and are not intended to be adequate for software design purposes. The
appropriate set of AT Ensemble Documents will be provided to the application developer under a
separate non-disclosure agreement as part of the Product Design Document. Note AT*E commands are
Ericsson defined commands that may be used by the customer.

If this module is intended to be used as a portable device, the OEM integrators should investigate separate approval to satisfy SAR requirements of 2.1093. Warning: Antenna Installation 1. 2. 4.2 At no time is the antenna to be located closer than 27 centimeters to a normally occupied location or person. At no time should an antenna system with greater than 1.0 dB gain be used with this module in any normally occupied area. In an automotive configuration, an antenna with a 2.5dB gain and a minimum 1.5 dB of cable loss should be used. Module Operation Safe and efficient use of this module requires a properly terminated antenna. DO NOT operate the module with a damaged or missing antenna, replace a damaged or missing antenna immediately otherwise damage to the module may result and could violate FCC regulations. DO NOT operate this device within 27cm of a person unless proper shielding from the antenna is installed. 4.3 OEM Labeling A label must be affixed to the outside of the end product into which the authorized module is incorporated, with a statement similar to the following: This device contains TX FCC ID: XXXXXX (where "XXXXXX" is the FCC ID of the module). 4.4 Posted Facilities Do not operate this device where posted notices require wireless devices to be turned off. 4.5 Electronic Devices Most electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded properly against RF signals. Pacemakers The Health Industries Manufacturers Association recommends that a minimum separation of six (6) inches be maintained between a wireless transmitter and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with the independent research and recommendations of Wireless Technology Research. Persons with Pacemakers should always keep the antenna/module more than 27cm from their pacemaker when the module is on; if you have a reason to suspect that interference is taking place, turn off the module immediately. Hearing Aids Some digital wireless devices may interfere with some hearing aids. Other Medical Devices If you use any other type of personal medical device in the presence of this transceiver, consult the manufacturer of your device to determine if it is adequately shielded from external RF energy. Your physician may be able to assist you in obtaining this information. 4.6 Blasting Areas To avoid interfering with blasting operations, turn your module off when in a “blasting area” or in areas posted: “Turn off two-way radio”. Obey all signs and instructions. 4.7 Potentially Explosive Atmospheres Turn your module off when in any area with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include such areas as gasoline stations; below deck on boats; fuel or chemical storage or transfer facilities; vehicles using liquefied petroleum gas (such as propane or butane); areas where the air contains chemicals or particles, such as grain dust or metal powders; and any other area where you would normally be advised to turn off your vehicle engine. 4.8 Vehicles RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also consult the manufacturer of any equipment that has been added to your vehicle. 4.9 For Vehicles Equipped with an Airbag An airbag inflates with a great force. Do not place objects including both installed or portable wireless equipment in the area over the airbag or in the airbag deployment area. If in-vehicle wireless equipment is improperly installed and the airbag inflates, serious injury could result. 4.10 Responsible Use OEM Manufacturers providing telematic devices for vehicular use are encouraged to incorporate the following CTIA guidance for safe and responsible wireless phone use into their user’s manuals: A Guide to Safe and Responsible Wireless Communication Device Use TENS OF MILLIONS OF PEOPLE IN THE U.S. TODAY TAKE ADVANTAGE OF THE UNIQUE COMBINATION OF CONVENIENCE, SAFETY AND VALUE DELIVERED BY THE WIRELESS TELEPHONE. QUITE SIMPLY, THE WIRELESS COMMUNICATION DEVICE GIVES PEOPLE THE POWERFUL ABILITY TO COMMUNICATE BY VOICE--ALMOST ANYWHERE, ANYTIME--WITH THE BOSS, WITH A CLIENT, WITH THE KIDS, WITH EMERGENCY PERSONNEL OR EVEN WITH THE POLICE. EACH YEAR, AMERICANS MAKE BILLIONS OF CALLS FROM THEIR WIRELESS PHONES, AND THE NUMBERS ARE RAPIDLY GROWING. However, an important responsibility accompanies those benefits, one that every Wireless Communication Device user must uphold. When driving a car, driving is your first responsibility. A Wireless Communication Device can be an invaluable tool, but good judgment must be exercised at all times while driving a motor vehicle--whether using the Wireless Communication Device or not. The basic lessons are ones we all learned as teenagers. Driving requires alertness, caution and courtesy. It requires a heavy dose of basic common sense---keep your head up, keep your eyes on the road, check your mirrors frequently and watch out for other drivers. It requires obeying all traffic signs and signals and staying within the speed limit. It means using seatbelts and requiring other passengers to do the same. But with Wireless Communication Device use, driving safely means a little more. This brochure is a call to Wireless Communication Device users everywhere to make safety their first priority when behind the wheel of a car. Wireless telecommunications is keeping us in touch, simplifying our lives, protecting us in emergencies, and providing opportunities to help others in need. When it comes to the use of a Wireless Communication Device, safety is your most important call. Wireless Communication Device "Safety Tips" Below are safety tips to follow while driving and using a Wireless Communication Device, which should be easy to remember. 1. Get to know your Wireless Communication Device and its features such as speed dial and redial. Carefully read your instruction manual and learn to take advantage of valuable features most phones offer, including automatic redial and memory. Also, work to memorize the communication device keypad so you can use the speed dial function without taking your attention off the road. 2. When available, use a hands free device. A number of hands free Wireless Communication Device accessories are readily available today. Whether you choose an installed mounted device for your wireless communication device or a speaker communication device accessory, take advantage of these devices if available to you. 3. Position your Wireless Communication Device within easy reach. Make sure you place your Wireless Communication Device within easy reach and where you can grab it without removing your eyes from the road. If you get an incoming call at an inconvenient time, if possible, let your voice mail answer it for you. 4. Suspend conversations during hazardous driving conditions or situations. Let the person you are speaking with know you are driving; if necessary, suspend the call in heavy traffic or hazardous weather conditions. Rain, sleet, snow and ice can be hazardous, but so is heavy traffic. As a driver, your first responsibility is to pay attention to the road. 5. Do not take notes or look up phone numbers while driving. If you are reading an address book or business card, or writing a "to do" list while driving a car, you are not watching where you are going. It's common sense. Don't get caught in a dangerous situation because you are reading or writing and not paying attention to the road or nearby vehicles. 6. Dial sensibly and assess the traffic; if possible, place calls when you are not moving or before pulling into traffic. Try to plan your calls before you begin your trip or attempt to coincide your calls with times you may be stopped at a stop sign, red light or otherwise stationary. But if you need to dial while driving, follow this simple tip--dial only a few numbers, check the road and your mirrors, then continue. 7. Do not engage in stressful or emotional conversations that may be distracting. Stressful or emotional conversations and driving do not mix--they are distracting and even dangerous when you are behind the wheel of a car. Make people you are talking with aware you are driving and if necessary, suspend conversations, which have the potential to divert your attention from the road. 8. Use your Wireless Communication Device to call for help. Your Wireless Communication Device is one of the greatest tools you can own to protect yourself and your family in dangerous situations--with your communication device at your side, help is only three numbers away. Dial 9-1-1 or other local emergency number in the case of fire, traffic accident, road hazard or medical emergency. Remember that it is a free call on your Wireless Communication Device! 9. Use your Wireless Communication Device to help others in emergencies. Your Wireless Communication Device provides you a perfect opportunity to be a "Good Samaritan" in your community. If you see an auto accident, crime in progress or other serious emergency where lives are in danger, call 9-1-1 or other local emergency number, as you would want others to do for you. 10. Call roadside assistance or a special wireless non-emergency assistance number when necessary. Certain situations you encounter while driving may require attention but are not urgent enough to merit a call for emergency services. But you still can use your Wireless Communication Device to lend a hand. If you see a broken-down vehicle posing no serious hazard, a broken traffic signal, a minor traffic accident where no one appears injured or a vehicle you know to be stolen, call roadside assistance or other special non-emergency wireless number. Careless, distracted individuals and people driving irresponsibly represent a hazard to everyone on the road. Since 1984, the Cellular Telecommunications Industry Association and the wireless industry have conducted educational outreach to inform Wireless Communication Device users of their responsibilities as safe drivers and good citizens. As we approach a new century, more and more of us will take advantage of the benefits of Wireless Communication Devices. And, as we take to the roads, we all have a responsibility to drive safely.
