7.2.9.9 Set interface
The AlphaGUARD provides three interfaces: USB, RS232 and Bluetooth (for the
setup of the Bluetooth connection with a computer, see point
14.2). Just one
interface can be used at the same time and has to be selected before usage. The
other two interfaces are deactivated to reduce battery consumption. The
interface can be selected by using the Scroll up or the Scroll down button. The
selection has to be acknowledged by pushing the Enter button.

interface hardware used by the PC it may also be possible to work with the
maximal baud rate of 115 200 B
