1 GSM Voice Modem User Manual 2 Read First Before operating the system, please read this manual thoroughly, and retain it for future reference. Attention Please not leave the GSM Voice Modem.The GSM Voice Modem can only be used after has a valid SIM card inserted. Please do not remove the shielding cover. Warning Hangzhou Tuolima Network Technologies Co., Ltd.will not fix the GSM Voice Modem that is opened by user.In such case, its warranty will be terminated too. 1. Summary More and more applications emerged with the rapid development of wireless data services, such as vehicle navigation, remote monitoring, wireless Internet access, wireless POS, etc. Thus, more and more devices need to be able to do wireless communication. With this background, Hangzhou Tuolima Network Technologies Co., Ltd. develops its GSM Voice Modem. Users of this product can add wireless communication capability easily to their own products, and then, develop many applications. The GSM Voice Modem mostly fits the need of data transfer, with SMS data communication, GPRS data navigation, Circuit Switch / Data Connectivity, TCP/IP protocol etc. Because the easy setting up in SCM (Single Chip Micyoco), it is convenient for network data communication. The GSM Voice Modem with small size, which fits both embedded application and external peripheral equipment. The AT command set and USB interface will offer easy data connection without any extra circuit control. Traditionally, the above applications use digital cellular, CDPD or other wire-line modem to do communication, and these technologies are of the disadvantages of high communication expense, limited communication range, dial before communications, etc. When we begin to use GSM Voice Modem, all these problems disappeared. Please read this manual carefully before your installation, and please keep this manual for further reference. 3 2. Interfaces 1 USB port, SIM Card Holder 3.

A new window will appear, from here you can test your modem by selecting “Diagnostics” to ensure you have selected the appropriate COM port. Click on the “Advanced” tab and enter the setting. Please note that you will need to obtain your APN (Access Point Name) from your cell phone provider to replace the “CMNET” value 13 You can then establish a dial up networking connection by double clicking your “My Network Places” icon, Selecting “View My Network Connections” and “Add a New Network Connection” option. You will also need to obtain your username and password from your ISP, your number to dial is *99# 14 Warning: This device complies with part 15 of the FCC Rul…

Circuit Description 1. Overview: The GSM Voice Modem works at 1900 MHz GSM band And CPU runs at 26MHz, with 64M bits Flash Memory and 32Mbits SRAM. The main IC include CPU(MT6223D),Flash( M36W0R6050T3ZAQ ),Transceiver(AD6548),PA(SKY77517) System diagram Overview: 1.1. RF: RF (Radio Frequency) section is in charge of the signal transmit and receiving, signal modulation and demodulation. Product technical parameters: GENERAL: Signal Flow Brief of the mobile signal flow as below: 3.1. Transceiver Transceiver (AD6548) dedicates to signal modulation and demodulation. Receiver mode: The receiver section includes 1900 MHz GSM band Low-Noise Amplifiers(LNAs), RF quadrature mixers, channel filters, Programmable-Gain Amplifiers(PGAs), and on-chip automatic DC-offset correction loops. The fully-integrated channel filters reject interference and blocking singals without any external components. The differential inputs are matched to external SAW filters using LC networks and the H/L gain step is 36dB. Following the LNAs are two quadrature RF mixers that down-convert the RF signal to IF I/Q signals. The IF I/Q signals are then filtered and amplified through a low-pass filter and a PGA. The multi-stage PGA is implemented between filtering stages to control the gain of the receiver. Transmitter mode: The transmitter section consists of Base-band (BB) I/Q filters, I/Q modulators, frequency dividers, output buffers and a bias-core circuit. BB I/Q signals are fed into the one-pole RC low-pass filter first for better out-of-the-band noise performance. The I/Q modulators are responsible for translating the BB I/Q signals to the transmitting frequencies. The low-noise divided-by-2/4 frequency dividers provide the necessary carriers for frequency translation while minimizing VCO pulling effect. The output buffers are adopted to amplify the modulator output signals to an adequate level to fulfill Pin requirement of Power Amplifiers. 3.3.

Tune-up Procedure Tune-up Procedure During manufacturing will be individually calibrated. The measurement is done in a fully calibrated setup, which is based on Agilent 8960 (adjustement of gain factors) and Agilent 8960 or RS CMU200 (control of power levels). Furthermore, the highest power level is verified afterwards in a GSM Voice Modem measurement on three channels (low, mid and high). Procedure: 1. Set operational voltage and on one certain channel in a special service mode by means of company proprietary software. 2. The actual power is measured at several power levels. 3. The gain factors are adjusted via the Board-test SW using automatic adjustment arithmetic until the target value is met. The appropriate gain control settings are stored in RF table (a special section in Nor Flash marked with Read only and untouchable for end user) individually (for each power level). The user has no possibility to change these settings later on.
