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.

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 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.

The key pad interface is consists of 4X5 matrix pattern. 5-KEYSENSE/[4:0] pins can be
used to connect a matrix key pad to the modem. But all pins are not necessary, just
4-KEYSENSE/ pins are used. KEYSENSE/ pins are active low.
5-GPIO pins are necessary to make other side of matrix, 5-GPIO pins are must active
high. The general key pad matrix are below :
