Warning: Exposure to Radio Frequency Radiation

!

The radiated output power of this device is far below the FCC radio frequency exposure limits.

Nevertheless, the device should be used in such a manner that the potential for human contact

during normal operation is minimized. In order to avoid the possibility of exceeding the FCC

radio frequency exposure limits, human proximity to the antenna should not be less than 20cm

during normal operation and the gain of the antenna must not exceed 1.5dBi.

2. Overview

2.1 Application Descriptions

The CDMA Wireless Data Module is a complex consumer communications instrument that relies

heavily on both digital signal and embedded processor technologies. The Wireless Data Modules

manufactured by AnyDATA.NET support Code-Division Multiple Access (CDMA). This operates in

both the cellular and PCS spectrum.

In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data

Module, AnyDATA.NET has successfully developed the DT2000 series. The DT2000-Dual is

AnyDATA.NET’s latest compact Wireless Data Module operating in the Cellular and PCS spectrum. The

DT2000-Dual also contains a complete digital modulation and demodulation system for CDMA standards

as specified in IS-95 A/B and IS-2000.

The subsystem in the DT2000-Dual includes a CDMA processor (MSM5100), an integrated

CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward

link data communications at a rate of 230.4kbps.

The DT2000-Dual provides an external interface that includes the standard RS-232, Digital Audio,

External reset control, LCD Display, Keypad, and Ringer extension ports.

The DT2000-Dual has the capability to power down unused circuits in order to dynamically

minimize power consumption.

* If not used as PCM, it can be used as a secondary UART for debugging. We strongly recommend that

the user has a 3-pin connector or 3 test points on their board, so that one can easily monitor and diagnose

their module.

** If the user wants the module to monitor battery voltage and the user is using a regulator in conjunction

with a battery, whose maximum voltage exceeds 4.3 V, to drive the module, then the user should please

contact our engineers.

When using a battery in which the voltage is between 3.3 V to 4.3 V and regulators aren’t used to drive

the module, leave this pin open.

4. Interface Descriptions

4.1 Overview

This chapter covers information required to convert the DT2000-Dual into a subscriber unit

application. In addition, some of the internal blocks of the device are described. Understanding these

internal blocks is necessary for one to completely grasp the functions of the various interfaces.

This chapter discusses the interface to the major blocks of the DT2000-Dual as shown in the

following figure. These blocks include:

4.2 CODEC Interface

The CODEC Interface is configured by internal and external figures. If the internal CODEC

interface is used, additional glue logic is not necessary and the module’s very simple audio interface can

be used. Otherwise if the internal CODEC interface is not used, an external CODEC is necessary to

support the car-kit system. In this case, the module provides a PCM CODEC Interface.

4.2.1 Internal CODEC Interface

The module contains analog audio interface circuitry. The contained audio interface supports all of the

required conversation and amplification stages for the audio front end.

The audio interface includes the amplification stages for both the microphone and earphone. The

interface supports one single-ended microphone input and one single-ended earphone output.

DESCRIPTION CHARACTERISTIC

MIC Input Analog Input (Pin No. 58) *

* MIC2, along with being a microphone input, checks to see if the user has pressed the headset key,

which allows the user to connect to or disconnect from a call. This pin is internally pulled high and is

therefore normally in the high state. To activate this input and connect to or disconnect from a call, the

user must set the MIC2 pin to a low state for 100ms to 200ms.

** EAR_DET1 checks to see if a headset has been connected to the ear-jack. When there is no headset

connected to the ear-jack, the audio path is disconnected. When a headset is connected to the ear-jack an

audio path is opened. To simulate a headset connected to the ear-jack, the user must apply a low signal to

the EAR_DET1 pin for as long as the user wants the audio path to be kept open.

4.3 UART Interface

4.3.1 Primary UART interface

The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that

TM

conforms to the RS-232 Interface protocol. The module provides 3.0V CMOS level outputs and 3.0V

CMOS switching input levels. In addition, all inputs have a 5.0V tolerance, however 3.0V or 3.3V CMOS

logic compatible signals are highly recommended.

All the control signals of the RS-232 are active low, however the data signals, RXD and TXD, are

active high.

The UART has a 64 byte transmit (TX) FIFO and a 64 byte receive (RX) FIFO. The UART features

hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no parity. The

UART operates at a maximum bit rate of 115.2kbps.

4.3.2 Secondary UART interface

The secondary UART is used to monitor and diagnose the status of the DT2000-Dual. It is strongly

recommended for the user to have the following secondary UART pins connected to an extra connector or

4.4 General Purpose Interface

The general purpose interface consists of 13 user-definable bi-directional pins.

Each GPIO pin can be configured as an input interrupt source. In addition, some GPIO pins can be

used as output control pins from the module. The user can define these pins properly as follows.

4.5 External Hardware Reset

There are two types of resets that the user can employ to restart the module. The first type will reset

the MSM and the memory and is performed when the user gives the AT command, AT+RESET, to the

MSM. Another way to reset the module is by using the external hardware reset. This type of reset will

reset the hardware as well as the MSM and the memory. The flash memory will be the only information

that is kept. To perform an external hardware reset, make sure the module has powered on and is not in

the initialization stage, and then apply a high signal of 2.5 V to 3.7 V to the external hardware reset pin

for 200ms to 500ms. Keep the external hardware reset pin low when the module is initializing as well as

during normal operation.

4.6 LEDs

The DT2000-Dual can indicate its current status through three pins. These three pins can be

connected to LEDs to more quickly and easily determine the status of the module. The SMS LED

indicates to the user if there is a SMS message or a voicemail message. If there is a SMS message or a

voicemail message, the SMS LED will turn on. After the user has read the SMS message or listened to the

voicemail message, the SMS LED turns off. Shortly after the module has been turned on, the Idle LED

should turn on indicating that the module is in-service. This means that the module is within the range of

the base station and is able to receive a signal from the base station. When the module is in traffic or

conversation stage, the Busy LED is on.

5.1.1 Absolute Maximum Ratings

Operating the module under conditions that exceed those listed in the Absolute Maximum Ratings

table may result in damage to the module.

Absolute Maximum Ratings should be considered as limiting values. The module may not function

properly and should not be operated if any one of the parameters is not within its specified operating

range.
