SIM345 EVB User Guide SIM345-EVB_UGD_V1.02 15.02.2008 176 Illustration 6.1 Running (1) Connect the SIM345 module to the 60 pins connector on SIM345 EVB, inserting 5V direct current source adapter, switching the S103 switch on off state, S202 switch on ON state; (2) Press the ON/OFF for about 2 second, and then SIM345 module begins running. You can see the light on the EVB flashing at a certain frequency. By the state, you can judge whether the EVB and SIM345 can run or not. No function and test can be executed when we have not connected necessary accessories. 6.2 Connecting Net and calling (1) Connect the serial port line to the MAIN serial port, open the HyperTerminal (AT command windows) on your Personal computer, the location of the HyperTerminal in windows2000 is START→accessory→communication→HyperTerminal. Set correct Baud Rate and COM number. The Baud Rate of SIM345 is 115200, and the COM number based on which USB port your serial port line insert in, you should select such as COM3 or COM4 etc. (2) Connect the antenna to the SIM345 module using an antenna transmit line, insert SIM card into the SIM card interface, and insert headphones or headset into its interface. (3) Act on the step of running which mentioned above, power on the system, typing the AT command in the HyperTerminal, and then the SIM345 module will execute its corresponding function. 6.3 Downloading Connect the serial port line to the MAIN serial port, connect the direct current source adapter, run the download program and press the START key, then switch the POWER switch on ON state, DOWNLOAD switch on ON state, and then EVB provide the function of downloading. 6.4 Turns off Turn off SIM345 module: press the ON/OFF for about 2 second, SIM345 module will be turned off.
●RF exposure requirements To allow compliance with RF exposure requirements，the SIM345’s maximum output power is 33dBm in GSM850/GSM900 band，or 30dBm in DCS1800/PCS1900 band，and the maximum antenna gain is 3dBi，and the minimum cable loss is 0.5db. ●The Antenna Parameter of SIM345 GSM850/GSM900 DCS1800/PCS1900 VSWR(Max.)Operation band ≤2.5 ≤2.5 VSWR(Min.)Outside the operation band ≥3 ≥3 GAIN(Min)(dBi) >0dBi > 1dBi Output Power (dBm) >30dBm >27dBm ●The Module’s Conducted Reception Characteristic GSM850/GSM900 DCS1800/PCS1900 Conducted RX Level @BER<2%(dBm) -106 -106 ●IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of about eight inches (20cm) between the radiator and your body. Contact us: Shanghai SIMCom Ltd.
