In August 1996 the Federal Communications Commission (FCC) of the United States
with its action in Report and Order FCC 96-326 adopted an updated safety standard for human
exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters. Those
guidelines are consistent with the safety standard previously set by both U.S. and international
standards bodies. The design of this device complies with the FCC guidelines and these
international standards.

Overview
1.1
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 support Code-Division-Multiple-Access(CDMA).
Operating both the cellular and PCS spectrum.
In a continuing effort to simplify the design and reduce the production cost of the Wireless
Data Modem. AnyDATA.NET has developed the DTS series. The DTS-800 CDK is
AnyDATA.NET ‘s latest compact Wireless Data Modem operating in Cellular spectrum, also
contains complete
digital modulation and demodulation system for CDMA standards as specified in IS-95 A/B.
The subsystem within the DTS-800 CDK include a CDMA processor (MSM3000), an
integrated CODEC with ear piece and microphone amplifiers, and an RS-232 serial interface
supporting forward link MDR data communications of 64kbps.
The DTS-800 CDK provides external interface.
External interface includes the standard RS-232, Digital Audio, External On/Off control, LCD
Display, Keypad, Ringer extension ports.
The DTS-800 CDK will power down unused circuits in order to dynamically minimize power
consumption.

The CODEC Interface configured by internal and external figures.
If use internal CODEC Interface, additional glue logic is not necessary. The modem provides
very simple audio interface.
Otherwise, An external CODEC is necessary support for car-kit system. The modem provides
PCM CODEC Interface.
3.2.1 Internal CODEC Interface
The modem contains analog audio interface circuitry. Contained audio interface
supports all of 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 differential microphone input and one differential
earphone output.

Interface Description
DTS-800 Reference Manual Application Information
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data
that conforms the RS-232 Interface protocol. The modem provides 3.0V CMOS level outputs
and 3.0V CMOS switching input level. And all inputs have 5.0V tolerance but 3.0V or 3.3V
CMOS logic compatible signals are highly recommended.
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.
