To enable the module to switch OFF correctly, the level shifter outputs (module
side) or host processor outputs must be set at low level (0V) or in high
impedance.
Typical implementation with a terminal:
VCC
+3V
+3V
+3V

Typical implementation with a microprocessor:
The figure above shows a typical implementation when the WISMO Quik Q24x6
module is connected to a host microprocessor which is 2.8 V tolerant on the
serial port signals.
