6.1 Power Supply
Customer can use the DC adapter that SIMCom provides as the power source.
If customer does not use the adapter, then DC source should be satisfied with the following requirements.
zInput voltage range 5-30V
zNormalvoltage 12V
zCurrentability 1A
The following chapter introduces the power line that SIMCom provides to customers, customer can power the
terminal by connect the terminal to the DC source via this line.
The power line includes four lines as the following figure shows, and table 3 gives a detailed description.

Figure 10: Power interface
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 15: Speaker reference circuit
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.

Please refer to document [1] and document [2] for details.
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.
