3. Operation Procedures
3.1 Power on Module
3.1.1 The Module Single Power Supply
The b position on the EVB is the R203. If the module needs single power supply, it should be disconnected
R203 resistance and J203 before using, and then VBAT and GND test points of the a position connect to the external power supply.
As shown in the following figure.
Figure 11: The module single power supply
3.1.2 Power on Operation Procedures
The module power on procedure as is shown in the following:
⑴
Connect the DC adapter.
⑵
Connect the module to J101 on SIM8200-M2-EVB2.
⑶
Pull S103 to ON state, the LED101 will be lighted.
⑷
Pull S102 to ON state, and the module will be powered on, if the module registered the net, the LED201 will be lighted flash, if no registered the net, the LED201 will be lighted all the time. www.simcom.com 21/35

SIM8200 series module provides a full-featured serial port. By default, when used as an ordinary serial port, we can set the data frame format of the serial port and set the baud rate and other operations.
(1) Set the serial data frame format
SIM8200 series module supports multiple serial data frame formats. The default data frame format is 8 data bits, 1 stop bit, and no parity bit.

Supported formats
8bit/7bit

1bit
Odd, Even, None
If you need to modify the data frame format, please refer to the instruction AT + ICF. Common data frame format settings are as follows
：

AT+ICF=4
、
AT+ICF=4,2
7 Data bit 1 Stop bit odd check
7 Data bit 1 Stop bit even check
AT+ICF=3,0
AT+ICF=3,1
(2) Set the serial port baud rate
SIM8200 series module supports a variety of common baud rates. The standard factory default baud rate is
115200, and it supports automatic baud rate adaptation. There are two methods to modify the baud rate.
For temporary modification and long-term modification, please refer to the instruction AT + IPR for temporary modification. Please refer to AT + IPREX for long-term modification of the baud rate. The serial port baud rate is modified for a long time, and the baud rate will be saved locally, so it will continue to take www.simcom.com 29/35
SIM8200-M2-EVB2 User Guidelines Manual V1.01 effect after the next boot. The temporary modification of the serial port baud rate will be invalidated after restart. The baud rate will be restored to the locally saved baud rate.

(3) Set serial data flow control the serial port of SIM8200 series module adopts RTS / CTS flow control mode, but the full-featured serial port of SIM8200 series module works by common serial mode by default.
If we need to set the working mode of serial flow control, please refer to AT + IFC.

The method of using serial port RTS flow control can be verified by using the serial port tool. When RTS flow control is set, if RTS is not checked, it means that RTS does not take effect. At this time, two www.simcom.com 30/35
SIM8200-M2-EVB2 User Guidelines Manual V1.01 consecutive ATs are sent. It is found that the window of the serial port tool does not show AT and return value.
Figure 22: UART flow control method 1
Then check RTS to make RTS take effect, and then the window of serial tool will display AT and return value.

Marks Requirements
When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and not operate normally due to RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Forgetting to think much of these instructions may impact the flight safety, or offend local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. RF interference can occur if it is used close to TV sets, radios, computers or other electric equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for hands free operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember to use emergency calls. In order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.
Some networks do not allow for emergency call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile. www.simcom.com 35/35
