4.3.2 Secondary UART interface
The secondary UART is used to monitor and diagnose the status of the DT2000-Dual. It is strongly
recommended for the user to have the following secondary UART pins connected to an extra connector or
to test points, in order to easily troubleshoot any problems with the module.

4.4 General Purpose Interface
The general purpose interface consists of 13 user-definable bi-directional pins.
Each GPIO pin can be configured as an input interrupt source. In addition, some GPIO pins can be
used as output control pins from the module. The user can define these pins properly as follows.

There are two types of resets that the user can employ to restart the module. The first type will reset
the MSM and the memory and is performed when the user gives the AT command, AT+RESET, to the
MSM. Another way to reset the module is by using the external hardware reset. This type of reset will
reset the hardware as well as the MSM and the memory. The flash memory will be the only information
that is kept. To perform an external hardware reset, make sure the module has powered on and is not in
