2. Overview
2.1 Application Descriptions
The CDMA Wireless Data Modem is a complex consumer communications instrument that relies
heavily on both digital signal and embedded processor technologies. The Wireless Data Modem
manufactured by AnyDATA.NET supports Code-Division-Multiple-Access (CDMA). This operates in
800MHz CDMA and 1900MHz PCS spectrum.
In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data
Modem, AnyDATA.NET has successfully developed the EMIV-DUAL. The EMIV-DUAL is
AnyDATA.NET’s latest compact Wireless Data Modem operating in 800MHz CDMA and 1900MHz
PCS spectrum, also contains complete digital modulation and demodulation system for CDMA standards
as specified in IS-95 A/B and IS-2000.
The subsystem within the EMIV-DUAL includes a CDMA processor (MSM6050), an integrated
CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward
link data communications of a rate of 153kbps.
The EMIV-DUAL provides external interface. External interface includes the standard RS-232,
Digital Audio, External reset control, parallel LCD Display, Keypad, Ringer extension ports and R-UIM
for China market.
The EMIII-DUAL has the capability to power down unused circuits in order to dynamically
minimize power consumption.

4. Interface Descriptions
4.1 Overview
This chapter covers information required to design the EMIV-DUAL into a subscriber unit
application. In addition, the internal signals that are necessary for complete understanding of the UART
interfaces are described below.
4.2 RS232 Interface (Standard)
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms the RS-232 Interface protocol. The modem provides 5.0V CMOS level.
All the control signals of the RS-232 signals are active low, but data signals of RXD, and TXD Are
active high. The UART has a 64byte transmit (TX) FIFO and a 64byte receive (RX) FIFO. The UART
Features hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no
parity. The UART operates at a 115.2kbps maximum bit rate.

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15, Part22 and Part24 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
