Data communication interfaces 

SARA-R4 series modules provide the following serial communication interfaces: 

•

 

UART interfaces: asynchronous serial interface supporting AT commands, data communication, 
GNSS tunneling, FW update by means of FOAT. See section 

1.9.1

UART interfaces 

1.9.1.1

 

UART features 

SARA-R4 series modules include a primary main UART interface (UART) for communication with an 
application  host  processor,  supporting  AT  commands,  data  communication,  multiplexer  protocol 
functionality (see 

1.9.1.3

), FW update by means of FOAT, with settings configurable by dedicated AT 

commands (for more details, see the SARA-R4 series AT commands manual 

[2]

): 

•

 

8-wire serial port with RS-232 functionality conforming to ITU-T V.24 recommendation 

[7]

, with 

CMOS compatible signal levels (0 V for low data bit / ON state, 1.8 V for high data bit / OFF state) 

o

 

Data lines (

RXD

 as data output,

The default baud rate is 115’200

 b/s 

•

 

The default frame format is 8N1 (8 data bits, no parity, 1 stop bit) 

☞

 

The  UART  is  available  only  if  the  USB  is  not  enabled  as  AT  command  /  data  communication 
interface: UART and USB cannot be concurrently used for this purpose.  

☞

 

UART signal names of the cellular modules conform to the ITU-T V.24 recommendation 

[7]

: e.g. 

TXD

 line represents data transmitted by the DTE (host processor output) and received by the DCE 

(module input). 

☞

 

Hardware flow control is not supported by the  SARA-R410M-01B  or the  SARA-R410M-02B-00 
product versions. The 

RTS

 input line needs to be set low (= ON state) to communicate over the 

UART on the SARA-R410M-01B product versions. 

☞

 

DTR

 input of the module must be set low (= ON state) to have URCs presented over UART interface 

on the SARA-R410M-01B, SARA-R410M-02B, SARA-R410M-52B and SARA-R412M-02B product 
versions of SARA-R4 series modules. 

 

 

25

 Not supported by SARA-R422-00B, SARA-R422S-00B or SARA-R422M8S-00B modules 

26

 Not supported by the current product versions of the SARA-R410M or SARA-R412M modules. Not available on the SARA-R422, 

SARA-R422S or SARA-R422M8S modules. 

27

 Dedicated AT commands to communicate with external u-blox GNSS receiver are not supported by SARA-R410M-01B, SARA-R422, 

or SARA-R422M8S product versions 

28

 

DTR

, 

DSR

, 

DCD

 and 

RI

 pins can be alternatively configured, in mutually exclusive way, as secondary auxiliary UART interface (UART 

AUX) on SARA-R422, SARA-R422S and SARA-R422M8S modules.
