s Uniden Data 2000 Wireless CDPD PC Card Uniden Data 2000 Operation & Programming Guide 1-1 1 Uniden Data 2000 Introduction 1.1 What is the Uniden Data 2000? The Uniden Data 2000 is a wireless CDPD PC Card which enables most vendors’ laptops, handheld computers, and Personal Digital Assistants with Type II PC Card slots to communicate with host-based applications such as web servers, intranet servers, databases, dispatch systems, and other host computer systems. The Uniden Data 2000 uses the Internet suite of protocols running over the CDPD (Cellular Digital Packet Data) system. The product is fully Windows compatible, supporting Windows 95, Windows NT, and Windows CE, and provides a Graphical User Interface (GUI) which offers the user simplified access to operational status and statistics, as well as the ability to configure, control, and mon- itor the performance of the device. The Uniden Data 2000’s compact size makes it an easily portable communications tool that can be stored conveniently in a briefcase or purse when not in use. 1.2 What is CDPD? CDPD or Cellular Digital Packet Data is a wireless, public access, packet data standard designed to operate over existing analog cellular phone systems. Since it is designed to use existing cellular phone sys- tems, CDPD provides a large coverage area, low service pricing, and fast transaction execution. CDPD’s primary benefit is quick, inexpen- sive, and efficient transmission of data packets over the existing cellular network. Additional benefits include built-in encryption for security (where applicable); a billing structure which charges for message size rather than on-line time (depending on individual service provider’s ser- vice plans); forward error correction methods that reduce the effects of noise and interference on the airlink; and availability. s Uniden Data 2000 Wireless CDPD PC Card 1-2 1.3 What is the PCMCIA Standard for PC Cards? Over the past several years, mobile computers have experienced explo- sive growth. While prices have fallen sharply, features are becoming more advanced and reliability has been greatly improved. One of the most notable features of today’s mobile computers is the PC Card slot. Over the last four years, the personal computer industry has rapidly adopted the PC Card slot feature, and today nearly 75 percent of laptops include a PC Card slot. This has been the driving force in the innovation and development of PC Card technology. In 1989, an international standards body and trade association was founded, called the PCMCIA (Personal Computer Memory Card Inter- national Association.). This organization was founded in order to estab- lish standards for Integrated Circuit cards and to promote interchangeability among mobile computers where ruggedness, low power, and small size are critical. Even though PCMCIA is a rather young technology, it has been quickly adopted by every major personal computer manufacturer in the world. Since it’s inception, PCMCIA has published a PC Card Standard which contains all of the physical, electrical and software specifications for PC Card technology. This standard is in a constant state of improvement by the PCMCIA technical committee. s Uniden Data 2000 Wireless CDPD PC Card Uniden Data 2000 Operation & Programming Guide 1-3 1.4 Product Highlights •Compatible with most vendors’ laptops, handheld computers and Personal Digital Assistants (PDAs) with PCMCIA Type II PC Card slots. •Windows compatible (Windows 95, Windows NT, and Win- dows CE.) •Graphical User Interface (GUI) provides simplified access to operational status and statistics, and allows the user to config- ure, control, and monitor the performance of the device. •AT command interface allows the user to query status and sta- tistics, change operational modes, and configure and control the device. •External antenna connector allows a high gain antenna to be substituted for maximum performance. •Full Duplex operation with CDPD System Specification Ver- sion 1.1. •Data transfer via SLIP or PPP to a connected host, using the PCMCIA interface. •Embedded TCP/UDP/IP stack from which an embedded appli- cation can achieve data transfer capability to the CDPD net- work. •Embedded network connectivity application, for testing end-to- end connectivity. •Maximum of 10 unicast Network Equipment Identifiers (NEIs) which can be stored and activated one at a time. •Onboard battery for operation independent of host. •External power option for desktop use. s Uniden Data 2000 Wireless CDPD PC Card 1-4 **need photo 1.5 Package Contents •Uniden Data 2000 Wireless CDPD PC Card: The physical module containing all of the electronic and other hardware ele- ments.

Overview of the System 1 Functional Overviews .1 Hardware functional overview The physical dimensions and the power consumption requirements drive the system design concept into adopting a single MAC layer ASIC partitioned in such as a way that all non MAC protocol decision related processes are done in ASIC hardware. The main intent of the ASIC partition is to eliminate any computation intensive elements of the system from the MCU so that no DSP class processing power is needed. Furthermore, as power consumption is function of the system clock speed, an overall system clock speed of in the order of 2 Mhz is desirable. A dedicated PCMCIA controller will be used to interface with the host computer. A full duplex cellular transceiver will provided for the airlink interface. Figure 1.1 shows the overall block diagram of the design.

It will also synchronize with the forward channel in minimum time of less than 2 microslots. ASIC is responsible for performing Reed Solomon decoding and it passes the recovered data block to the MCU. In the reverse channel, the Channel Interface ASIC accepts pre-formatted data blocks from the MCU. It appends a 38 bit dotting sequence and negotiates the reverse airlink in accordance to DSMA procedure. A stand alone Reed Solomon encoder is made available to the MCU so that the 16 parity symbols are provided when a raw data block is presented to the encoder. As it can be seen from Figure 1, the Channel Interface ASIC provides other support functions. It provides AFC control signal and hard limiter threshold level for the forward channel operation. It also provides the power output step size and power output ramp-up ramp-down controls. The MCU is responsible for interfacing with the Channel Interface ASIC to obtain the incoming data blocks in the forward channel. It executes all layers of the CDPD protocols. The forward channel engine provides the MCU with the status of synchronization by summarizing the majority vote of each of the synchronization flags, the Reed Solomon error correction counts and the decode flags. From these information MCU determines the status of the forward engine synchronization, and it can reset the forward engine operation In the reverse channel, MCU dictates all access protocol action by constructing respective data blocks. All formatting of the reverse channel data block such as convolution encoding, interleaving, bit stuffing and continuity flag insertion is completed before the MCU delivers the formatted data block for transmission by the Channel Interface ASIC.

A DC Power capable of 6.3 to 4.0 Vdc with greater than 500 mA current capability. 4pcs AAA Alkaline Battery 2. PCMCIA Interface and Switch ON/OFF: The PCMCIA Interface test must be run for both 3.3 Vdc interface Host and 5 Vdc interface Host 1. Using a 3.3 Vdc interface Host: 1. Connect card to the Host PC, turn the switch to ON position. The Host will recognize the Card by displaying a PC Card ICON on the bottom right corner of the screen and if the speaker is turned on by making a hop “” sound. 2. Leave the Card in the Host PC, turn the switch to OFF position. The Host will drop the card by removing the PC Card ICON from the bottom right corner of the screen and if the speaker is turned on by making a plug out “” sound. 3. With the Card still in the Host, turn the Switch to ON position 4. Unplug the Card from the Host, turn the switch to On position while the Card is still out then insert it back to the Host slot 5. Plug the card to the Host, turn the Switch to ON position, open a communication software (i.e. Hyper Terminal or Procomm). While the communication software is open, type the following “AT” command. at <Enter > Receive an “OK” response from the Host. 2. Using a 5 Vdc interface Host: Procedure is same as 3.3Vdc interface Host. 3 3. Rx/Tx Mode Setting For stop the wide scanning mode, PC Card have to set the Rx_Mode or Tx_Mode. 1. Rx Mode Setting 1. Plug PC Card into PCMCIA slot and turn the PC Card on. 2. Type: “ at$chanset *** ” next type “ at reset ” to set the channel in *** and start receive mode. 3. To change the mode to wide scanning, type :” at$chanset 0 ” next type “ at reset ”. 2. Tx Mode Setting 1. Plug PC Card into PCMCIA slot and turn the PC Card on. 2. Type: “ at$syncgen 383 r” to start transmission with random data. 3. Type: ”at$txlevel 2” for setting wanted TX PWR level. 4. To change the TX PWR level type: “at$txlevel 3~7” .(*see comment) 5. To change the channel type: ” at$chan *** ” for setting wanted channel. 6. To change the mode to wide scanning, type ” at reset ”. 7. When check carrier suppression Type: “at$syncgen 383 0” then follow step 3~6. (* TX PWR level have 6 level step. Level 2 as highest PWR, Level 7 as lowest PWR each level is different by 4dB. See Section 4.3) 4. Calibrations For the transmit side, there are transmit power calibration and carrier suppression calibration. These two calibrations will be done at three different channels: low (channel 991), middle (channel 383) and high (channel 799). For the Receive side, only RSSI calibration is required at channel 383 only. 1. RSSI Calibration 1. Requirements The RSSI Calibration is to make the RSSI value( the reading power level) the same or near the real input level. Make the difference between real level and reading level meet the specification, i.e. + 6dB. The RSSI will be calibrated at channel 383 only. An external signal generator with GMSK modulation will be inputted to the antenna connector. The channel will be set to 383. The 13 RSSI level and their according real input power level as follow: RSSI LevelInput Power Level (dBm) 0-113 1-108 2-103 3-98 4-93 5-88 6-83 7-78 4 8-73 9-68 10-63 11-58 12-53 2. Procedure 1. Plug PC Card into PCMCIA slot and turn the PC Card on. 2. Type “ at$chan 383” after UnidenData 2000 turn on the receiver power. 3. Set the external signal generator to GMSK modulation, and set the out put level( make sure the input level at the antenna connector is the same as the level in the above form). 4. Type “ at$rssical v” the “v” is the according RSSI Level of the input level in the above form. 5. Repeat step 3 and step 4 for all 13 RSSI Level. 6. type “ at$rssiwrite” to write the new calibrated RSSI Table into EEPROM. 7. Type: “at$reset” to reset the PC Card. 2. Reference Frequency Calibration 1. Requirements Reference Frequency Calibration is to compensate for the TXCO initial frequency variation at room temperature. The reference frequency will be adjusted by monitoring the Tx frequency at channel 383 for 836.49MHz + 200 Hz. On the Reference Frequency Calibration, the TX carrier will be turned on continuously. And de-balance the I and Q signal to make the carrier level high. Then use spectrum analyzer to find the carrier frequency. Change the AFC output value to make the frequency accuracy meet the specification. This calibration is only done for channel 383. 2. Procedure 1. Plug PC Card into PCMCIA slot and turn the PC Card on. 2. Type: “ at$syncgen 383 r” . 3. Type “ at$write 0x4060 1 0x05” to bypass the I and Q, and set the AFC manually 4. Type “ at$write 0x4061 1 0x00” 5. Use the “Peak Finding” function of spectrum analyzer to find the carrier frequency. 6. Type “ at$write 0x4065 1 0x hh ” to adjust the Tx frequency manually. The default value for AFC is 0x94. Change the “hh” to adjust the carrier frequency until it is within 836.49MHz + 200 Hz. 7. Type “ at$afcwrite 0xhh ” to store the calibrated data into EEPROM. 8. Type: “at$reset” to reset the PC Card. 5 3. Tx Power Calibration 1. Requirements The PC Card UnidenData 2000 is a class III CDPD MES, its output power must operate over 11 levels as follow: LevelCDPD output Power spec (dBm) Calibration goals (dBm) 028, +2 / -427 + 0.5 128, +2 / -427 + 0.5 228, +2 / -427 + 0.5 324, +2 / -423 + 0.5 420, +2 / -419 + 0.5 516, +2 / …

EXPLANATION OF SAR TEST CONDITION (FCC ID: AMWUH302) Model: DATA 2000 EXHIBIT FOR APPLICATION FOR TYPE ACCEPTANCE The SAR test condition which Uniden DATA 2000 (CDPD Modem) was tested under would never exist even in the worst case operation. This is because the CDPD specification limits the maximum length of transmission to 64 blocks of data for one transmission burst. In between transmissions, A MES requires a lot of time for transmission preparation in forming the transmission data burst stream. In particular, each block of data are individually Reed Solomon (63,47) encoded before concatenated to form the burst data stream. It also requires to get transmission requests from the forward channel before the subsequent transmission can take place. In most cases, the minimum delay the baseband station will take before issuing a transmission request is about 30-block time. Within the DATA 2000 software design, the optimization for the processor load sharing with the higher layer protocol and the physical layer preparation requires an idle time of at least 750 mSec. Thus in the case of one MES per base station where there is no power control situation, DATA 2000 will have a maximum capability of 50% transmission duty cycle. However, this is also a scenario that will have almost zero probability of taking place.
