Hardware Interface
A. UART interface:
10
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.

Null modem
GPIO
If UART port is used in Null Modem, the pin “RI” can be used as an interrupt signal
to HOST. Normally it will keep high logic level until certain condition such as
receiving SMS, voice call (CSD, video) or URC reporting, then “RI” will change to
11
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”.
13
D. I2C Interface:
I2C is used to communicate with peripheral equipment and can be operated as either
a transmitter or receiver, depending on the device function. Use AT Commands
“AT+CRIIC and AT+CWIIC” to read/write register values of related peripheral
equipment connected with I2C interface.
Both SDA and SCL are bidirectional lines, connected to a positive supply via a pullup resistor respectively. When the bus is free, both lines are high.
For RC3000A, the data on the I2C bus can be transferred at rates up to 400kbps. The
number of peripheral devices connected to the bus is solely dependent on the bus
capacitance limit of 400pF. Note that PCB traces length and bending are in users’
control to minimize load capacitance.
Note:I2C_SDA and I2C_SCL have been pulled up with two 2.2kR resistors to 2.6V
level in module. So there is no need to pull them up in users’ application circuit.
E. SPI Interface:
SPI interface of RC3000A is master only. It provides a duplex, synchronous, serial
communication link with peripheral devices. Its operation voltage is 1.8V, with
clock rates up to 26 MHz.
F. GPIO Interface:
RC3000A provides a limited number of GPIO pins. All GPIOs can be configured as
inputs or ouputs. User can use AT Commands to read or write GPIOs status.
Note-1: If more GPIOs need to be used, users can configure GPIO on other multiple
function interfaces, such as PCM.
Note-2: The output driver current of GPIOs is 2mA.
G. PCM Interface:
RC3000A provides hardware PCM interface for external codec. The PCM interface
enables communication with an external codec to support hands-free applications.
RC3000A PCM interface can be used in two modes: the default mode is auxiliary
PCM (8 KHz long sync mode at 128 KHz PCM CLK). In short-sync (primary PCM)
mode, RC3000A can be a master or a slave. In long-sync (auxiliary PCM) mode,
RC3000A is always a master. RC3000A also supports 3 kinds of coding formats: 8
bits (υ-law or A-law) and 16 bits (linear).
Note: PCM interface is multiplexed from GPIO (default setting). The AT command
“AT+CPCM” is used to switch between PCM and GPIO functions.
ADC Interface:
RC3000A has a dedicated ADC that is available for digitizing analog signals such as
battery voltage and so on; it is on PIN 35 and PIN 36, namely ADC1 and ADC2.
14
This ADC is 12 bit successive-approximation circuit, and electronic specification is
shown in the following table.

Global Positioning System (GPS)
RC3000A merges GPS satellite and network information to provide a high-availability
solution that offers industry-leading accuracy and performance. This solution performs
well, even in very challenging environment conditions where conventional GPS receivers
fail, and provides a platform to enable wireless operators to address both location-based
services and emergency mandates.

Note: Performance will vary depending on the environment, antenna type and signal conditions
and so on.
RC3000A supports both A-GPS and S-GPS, and then provides three operating modes: mobileassisted mode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and
mobile-based mode.
In mobile-assisted mode, when a request for position location is issued, available network
information is provided to the location server (e.g. Cell-ID) and assistance is requested from the
location server. The location server sends the assistance information to the handset. The
handset/mobile unit measures the GPS observables and provides the GPS measurements along
with available network data (that is appropriate for the given air interface technology) to the
location server. The location server then calculates the position location and returns results to
the requesting entity.
In mobile-based mode, the assistant data provided by the location server encompasses not only
the information required to assist the handset in measuring the satellite signals, but also the
information required to calculate the handset’s position. Therefore, rather than provide the GPS
measurements and available network data back to the location server, the mobile calculates the
location on the handset and passes the result to the requesting entity.
In standalone (autonomous) mode, the handset demodulates the data directly from the GPS
satellites. This mode has some reduced cold-start sensitivity, and a longer time to first fix as
16
compared to the assisted modes. However, it requires no server interaction and works out of
network coverage.
This combination of GPS measurements and available network information provides:
• High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural
• High availability that is enabled by using both satellite and network information
Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell
geometry/density, and while unassisted, GPS-only solutions typically perform poorly indoors.
The RC3000A GPS solution provides optimal time to fix, accuracy, sensitivity, availability, and
reduced network utilization in both of these environments, depending on the given condition.

This device is to be used only for mobile and fixed application. End-users must be
provided with transmitter operation conditions for satisfying RF exposure compliance.
OEM integrators must ensure that the end user has no manual instructions to remove or
install RC3000A modem. Antennas used for this OEM module must not exceed 3dBi
gain for mobile and fixed operating configurations.
GSM Antenna – Installation Guidelines
• Install the antenna in a place covered by the GSM signal. The Antenna must be
installed to provide a separation distance of at least 20 cm from all persons and
must not be co-located or operated in conjunction with any other antenna or
transmitter. In case of this requirement cannot be satisfied, the system integrator
has to assess the final product against the SAR regulation.
• Due to the RC3000A antenna characteristics to environmental sensitivity, the
antennas location should consider that the performance could be affected by a
building’s characteristics or other obstructions that may interfere with the
modules ability to make a strong connection to the intended cellular signal
provider.
21
•
The Antenna must not be co-located or operated in conjunction with any other
antenna or transmitter.
Antenna shall not be installed inside metal cases.
•
Antenna shall be installed also according Antenna manufacturer instructions.

SIM (Subscriber Identity Module) Card Information
To access a cellular network you must purchase a compatible SIM card. The GSM
modules have a SIM card slot located on the bottom of the PCB. The SIM card has to be
handled with care, avoiding any contact with the pins because electrostatic discharges
may damage the product itself. Please read the SIM manufactures instructions prior to
installing.
Do not insert or remove the SIM card when the product is in power saving mode.
The SIM interface complies with the GSM Phase 1 specification as well as GSM Phase
2+ specification for FAST 64 kbps SIM card. The module supports both 1.8Volt and 3
Volt SIM cards. The SIM card is enabled with the AT+CSDT command.

Introduction to Modem Operation-The AT Command Set
RC3000A modules are used to originate or answer telephone calls and establish links
with other devices for the purpose of transmitting voice, data, or fax information between
two locations. Please refer to the SIM900 AT Command Manual for complete AT
command listings and information
After installation, you will now be able to communicate with the modem and establish
connections with remote devices. Controlling the modem functions is accomplished by
using “AT” commands. These commands are used to instruct the modem to perform
functions such as dialing or to answers calls. These commands are normally
automatically issued by communication software. However for some applications,
custom software may have to be written due to the absence of a normal operating system
such as DOS or Windows.
NOTE: The first AT command issued must be Upper Case AT. Subsequent AT
commands can be either Upper Case or Lower Case.
The modem will automatically accept and process “AT” commands at most standard
DTE (Data Terminal Equipment) speeds and parity settings. For each command issued,
the modem will respond with a result code informing you of the modem’s status. The
format of a basic “AT” command and result code is as follows:
AT  
OK
AT = ATtention what follows is a command
 = any valid command
 = Carriage Return or Enter Key
OK = Result code meaning: the modem has accepted the command

replace or refund the purchase price of this Product, provided it is returned in accordance
with the terms of this warranty to RRI. Repair, at the option of RRI, may include the
replacement of parts, boards or other components with functionally equivalent
reconditioned or new parts, boards or other components. Replaced parts, boards or other
components are warranted for the balance of the original applicable warranty period. All
replaced items shall become the property of RRI.
RRI MAKES NO GUARANTEE OR WARRANTY THAT THE PRODUCT WILL

warranty for the Product manufactured by RRI, and RRI assumes no obligation or
liability for additions or modifications to this warranty. In no case does RRI warrant the

RRI is not responsible in any way for any ancillary equipment not furnished by RRI that
is attached to or used in connection with the Product, or for operation of the Product with

require availability of repeater stations or of particular radio frequencies, RRI assumes no
liability for range, coverage or suitability of the Product for any particular application.

the Product, and that buyer is not relying on RRI’s skill and judgment to select or furnish
suitable goods.

(a) Defects or damage resulting from use of the Product in other than its normal and
customary manner.
41
(b) Defects or damage from misuse, accident or neglect.
(c) Defects of damage from improper testing, operation, maintenance, installation,
alteration, modification or adjustment.
(d) Disassembly or repair of the Product in such a manner as to adversely affect
performance or prevent adequate inspection and testing to verify any warranty claim.
(e) Any Product that has had its serial number or date code removed or made illegible.

WARRANTIES. ANY APPLICABLE IMPLIED WARRANTIES, INCLUDING
WITHOUT LIMITATION THE IMPLIED WARRANTY OF MERCHANTABILITY,
ARE LIMITED TO THE DURATION OF THIS LIMITED WARRANTY. TO THE
FULLEST EXTENT PERMITTED BY LAW, RRI DISCLAIMS ANY LIABILITY
FOR DAMAGES IN EXCESS OF THE PURCHASE PRICE OF THE PRODUCT, FOR
ANY LOSS OF USE, LOSS OF TIME, INCONVENIENCE, COMMERCIAL LOSS,
LOST PROFITS OR SAVING OR OTHER INCIDENTAL, SPECIAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
