5. EVB and accessory equipment

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

Figure 19: EVB and accessory equipment

6. Illustration:

6.1 GSM part

6.1.1 Running:

(1) Connect the SIM508 module to the 80pins connector on the SIM508 EVB, insert the 5V

direct current source adapter, switch shifter S1 on the RUN state, shifter S2 on the ON

state;

(2) Press the GSM_ON/OFF button Z1 for about 2 seconds , then the GSM part of SIM508

begins to run.

You will see the light GSM_NET on the EVB glittering at a certain frequency corresponding

to various states, then you can judge whether the EVB and SIM508 is running or not. No

function and test can be executed when we have not connected necessary accessories.

SIM508-EVB_UGD_V1.01 Page 22 of 25

SIM508 EVB User Guide SIMCOM

6.1.2 Connecting Net and calling

(1) Connect the serial port line to the GSM_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 the

correct baud rate and COM number. The default baud rate of SIM508 is 115200 bps, and

the COM number based on which port your serial port line insert in, you should select

such as COM1，COM3 or COMx etc.

(2) Connect the GSM antenna to the SIM508 module using an antenna transmit line, insert

SIM card into the SIM card interface, insert headphone or handset 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 SIM508 module will execute its

corresponding function.

6.1.3 Downloading

Connect the serial port line to the GSM_MAIN serial port, connect the direct current source

adapter, run the download program and press the START key, then switch shifter S2 on the

ON state, shifter S1 on the D/L state, then the download procedure is executing

6.1.4 Turn off

Press the GSM_ON/OFF button Z1 for about 1 second, the GSM part of SIM508 will be

turned off.

6.1.5 Charging

Connect the SIM508 module to the 80pin connector interface and the external battery to

charging interface, which have been provided on the EVB. Insert the direct current source

adapter; switch shifter S2 on the OFF state, shifter S5 on the ON state, then the SIM508 will

go to the charging state.

6.2 GPS part

6.1.1 Running:

(1) Connect the SIM508 module to the 80pins connector on the SIM508 EVB, insert the 5V

direct current source adapter.

(2) Switch shifter S3 & shifter S4 on the RUN state, shifter S6 on the GPS_TXA state.

(3) Switch shifter S2 & shifter S7 on the ON state, then the GPS part of SIM 508 begins to

run.

SIM508-EVB_UGD_V1.01 Page 23 of 25

SIM508 EVB User Guide SIMCOM

You will see the GPS indicator (RX/TX_LED) on the EVB glittering at a 1Hz frequency, then

you can judge whether the EVB and the GPS part of SIM508 is running or not. No function

and test can be executed when we have not connected necessary accessories.

Note: Be sure of both shifter S3 and shifter S4 is on RUN state when the GPS part of
SIM508 is running normally, otherwise the GPS part of SIM508 will be on a undetermined
state.

6.1.2 Tracking the satellite signals

(1) Connect the serial port line to the GPS_COMA serial port

(2) Connect the GPS antenna to the SIM508 module using an antenna transmit line

(3) Run the GPS part of SIM508 as 6.1.1 described

(4) Then you will see the information transmitted by the GPS_COMA serial port in our demo

tool or through Hyper Terminal (AT Command widow)

6.1.3 Downloading

(1) Connect the serial port line to the GPS_COMA serial port,.

(2) Connect the direct current source adapter

(3) Switch shifter S3 on RUN state and shifter S4 on the D/L state

(4) Switch shifter S2 on the ON state and shifter S6 on the GPS_RXA state. (See note)

(5) Switch shifter S7 on the ON state

(6) Run the download program and press the execute key, and then the download procedure is

executing immediately.

Note: Step (4) is only for the judgement while program downloading form the PC side by
the glittering of the LED on EVB board, if you don’t need this visual indication or you can
judge by the response of the download program on the PC side directly, you can jump to
step (5) directly

。

6.1.4 Turn off and Reset

(1) Turn off: Switch shifter S7 on the OFF state, that will cut the power supply for the GPS

part directly, and then the GPS part of SIM508 will be turned off immediately.

(2) Reset: Press the button Z2 and release it lightly, the GPS part of SIM508 will reset

immediately, it’s necessary when system is running on a emergent state or encountering a

unpredictable malfunction and so on .
