EVB and accessory equipment At normal circumstance, the EVB and its accessory are equipped as the below figure:

Figure 9: EVB and accessory equipment 6. Operation Firstlyplease equip the module and accessories as the figure 9. 6.1 Power on and running

(1) Connect the SIM548Z module to the 80pins connector on the EVB, insert the 5V DC source adapter, switch S1 to the RUN state and S2 to the ON state, and the LED of B1 will light;

(2) Press the GSM_ON/OFF button Z1 for about 2 seconds, then the module is power on successful;

You will see the LED of B2 on the EVB glittering at a certain frequency corresponding to various states, and you can judge the EVB and SIM548Z are running correctly. No function and test can be executed when the necessary accessories are not connected. Page 10 of 12 6.2 Connecting the Net and calling

(1) Connect the serial port line to the serial port 1, open the HyperTerminal (AT command windows) on your personal computer, the location of the HyperTerminal in windows2000 is START accessory communication HyperTerminal. Set the correct baud rate and COM number firstly. The default baud rate of SIM548Z is 115200bps, and the COM number is based on which port your serial port line inserts in, you should select such as COM1COM3 or COMx etc;

(2) Connect the antenna to the SIM548Z module using an antenna transmit line, insert SIM card into the SIM card holder, and insert headphone or handset into its interface; (acts as the figure 9)

(3) Power on the module referring the description in 6.1, then type the AT command (such as ATIAT+CSQATD112 in the AT command document) in the HyperTerminal. If you get the correct response, it indicates the Hyper Terminal is successfully connected and the module is working correctly. About AT command and its response, please refer to the document of SIM508_ATC_V1.00.pdf. 6.3 Download and upgrade Connect the serial port line to the serial port 1, connect the DC source adapter, run the download flash tool and press the START key, then switch S2 to the ON state and S1 to the D/L state, and then the download procedure or upgrade procedure is starting. 6.4 Turn off Press the GSM_ON/OFF button Z1 for about 1 second, SIM548Z will be turned off. 6.5 Charge Connect the SIM548Z module to the 80pin connector interface and the external battery to charging interface provided on the EVB. Insert the DC source adapter; switch S2 to the OFF state and S5 to the ON state, then the SIM548Z goes into the charging state. 6.6 GPRS start-up Please see the document of GPRS Startup_V1.00.pdf 7 AT command the AT commands of SIM548Z are same as SIM508Z, also please see the document of SIM508_ATC_V1.00.pdf Page 11 of 12 8 FCC statements Please note:

SIM548Z complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) SIM548Z may not cause armful interference, and (2) SIM548Z must accept any interference received, including interference that may cause undesired operation. And changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 9 FCC RF exposure requirements To allow compliance with the FCC RF exposure requirements, the SIM548Zs maximum output power is 33dBm in GSM850/GSM900 band and 30dBm in DCS1800/PCS1900 bandand the maximum antenna gain is 3dBi and the minimum cable loss is 0.5dBThe antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter Page 12 of 12
