Hardware Interface
A. UART interface:

X
The RC3000A-E provides an UART (universal asynchronous serial transmission)
port. It consists of a flexible 7-wire serial interface. The module is as the DCE
(Data Communication Equipment) and the client PC is as the DTE (Data Terminal
Equipment). AT commands are entered and serial communication is performed
through UART interface.
The application circuit is in the following figures.

low logic level to inform the master (client PC). It will stay low until the master
clears the interrupt event with AT command.
If Full Modem is used to establish communication between devices, the pin “RI” is
another operation status. Initially it keeps high, when a voice call or CSD call comes,
the pin “RI” will change to low for about 5900ms, then it will return to high level for
100ms. It will repeat this procedure until this call is answered or hung up.
Note: RC3000A supports the communication rate: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, 921600, 3200000, 3686400,
4000000bps. Default rate is 115200bps.
B. Audio Interface:
RC3000A-E provides two analog signal outputs and one analog input. MIC1P/N is
used as microphone, EAR1P/N and SPK_P/N are used as audio output. Regarding
audio parameters configuration, please refer to the ATC manual.
There are three audio channels in RC3000A, including speaker output, receiver
output and microphone input. SPEAKER circuit in RC3000A is a Class-D amplifier.
Note: RC3000A has integrated MIC bias circuit. There is no need to pull the MIC1P
and MIC1N up to the external power, just connect it to microphone. MIC1P and
MIC1N must be differential lines.
Main audio parameters can be changed to satisfy users’ requirement. Here primary
register parameters and related description are listed. User can adjust them through
AT command.

C. USB Interface:
RC3000A-E module contains an USB interface. This interface is compliant with the
USB2.0 specification. The USB2.0 specification requires hosts such as the computer
to support all three USB speeds, namely low-speed (1.5Mbps), full-speed (12Mbps)
and high-speed (480Mbps). USB charging and USB-OTG is not supported.
Currently RC3000A supports the USB suspend and resume mechanism which can
help to save power. If not transaction is on USB bus, RC3000A will enter suspend
mode. When some events such as voice call or receiving SMS happen, RC3000A
will resume normal mode automatically.
Note: The RC3000A has two kinds of interface (UART and USB) to connect to host
CPU. USB interface is mapped to five virtual ports: “SIMTECH USB Modem”,
“SIMTECH NMEA Device”, “SIMTECH ATCOM Device”, “SIMTECH Diagnostics
interface” and “SIMTECH Wireless Ethernet Adapter”.
