When a valid power appears the terminal will power up automatic, for the MCU that inside the terminal processed
the power up part, MCU also acts as a Watch Dog, when the terminal runs wrong, MCU will cut off the power
and recover it immediately to restart the terminal.
6.2 Serial Interface
T5320 provides one asynchronous RS232 serial port (female).The RS232 standard interface serves to connect a
PC, Data Terminal Equipment (DTE) or other application, which acts as host controller of the T5320 Terminal
with all its functions. Through the RS232 interface it can be used as GSM/GPRS modem for sending and
receiving of SMS, Data and Fax calls.

6.3.1 Audio interface
T5320 has one pair of audio input and audio output; it can be connected to a speakerphone directly.
Figure 14: Speaker reference circuit
Firstly, customer must use the “AT +CSDVC=3” to select speaker audio channel.
Customer can set the terminal MIC gain level to make the sounds louder so that the listener can hear more clearly.
And if the sound a little lower on the terminal side, customer can use the “AT +CLVL” to make the sound higher
so that customer can hear clearly.
The AT commands should be send to the terminal by RS232 or USB interface, and the following table shows the
detail commands.

6.4 LED indicator
A red led indicates the power status, when a valid power appears, the red led will lighten up. But a lighten up red
led does not mean that the terminal has been powered up.
A green led indicates the terminal status and GSM net status, after the terminal been powered up and registered to
the network, it will blink at a certain frequency.

Description
This command is used to switch the speed of USB between high speed and full speed. If you just want to use full
speed to simplify the circuit then you can use this command to switch the USB speed. This command will save your
configuration so if you don’t change the speed the module will use the latest configuration forever.
This command will only takes effect on the next start-up.

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 to not operate
normally for 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. Forget to think much of these instructions may lead to the flight safety or
offend against 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, for example no mobile fee or a invalid SIM card.
While you are in this condition and need emergent help, please remember using 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.
