3.9. Serial Interfaces
The module provides four serial ports: UART Port, Debug Port, Auxiliary UART Port and GNSS UART
Port. The module is designed as DCE (Data Communication Equipment), following the traditional
DCE-DTE (Data Terminal Equipment) connection. Autobauding function supports baud rate from
4800bps to 115200bps.
The UART Port:
TXD: Send data to RXD of DTE.
RXD: Receive data from TXD of DTE.
RTS: Request to send.
CTS: Clear to send.
DTR: DTE is ready and inform DCE (this pin can wake the module up).
RI: Ring indicator (when there is a call, SMS or URC output, the module will inform DTE with the RI
pin).
DCD: Data carrier detection (the validity of this pin demonstrates successful set-up of the
communication link).
The Debug Port:
DBG_TXD: Send data to the COM port of peripheral.
DBG_RXD: Receive data from the COM port of peripheral.
The Auxiliary UART Port:
In
All-in-one
solution:
TXD_AUX: Send data to the GNSS part.
RXD_AUX: Receive data from the GNSS part.
In
Stand-alone
solution:
TXD_AUX: Keep open
RXD_AUX: Keep open
The GNSS UART Port
In
All-in-one
solution:
GNSS_TXD: Send data to the GSM part.
GNSS_RXD: Receive data from the GSM part.
In
Stand-alone
solution:
GNSS_TXD: Send GNSS data to the COM port of peripheral.
GNSS_RXD: Receive GNSS data from the COM port of peripheral.
