5. 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
Firstly，please 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.

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 COM1，COM3 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
ATI、AT+CSQ、ATD112 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）

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 SIM548Z’s maximum output
power is 33dBm in GSM850/GSM900 band and 30dBm in DCS1800/PCS1900 band，and the
maximum antenna gain is 3dBi and the minimum cable loss is 0.5dB。The 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。
