NOTE: Although in the TOP ZONE serigraphy it is shown Q0.9 & Q0.8 pins, in the reality they
are I0.3 I0.2 pins respectively. Additionally although the serigraphy only is expressed for the
RS485 it is also the same for the RS232. So if it is desired to enable any of the Hardware Serial
connection this is the function of these switches. See chapter 8 for more information

Switch configuration
8.1 General Switches Configuration
LEFT ZONE.
Communications and inputs/outputs cannot work simultaneously.
*I2C switch serigraphy is turned around. It should be: (SDA-D2 , SCL-D3). RX-RS485 should be RE-RS485
6. DE-RS485 – If this switch is ON, the A0.2-Q0.2 switch must be set to OFF. Being in ON mode
it enables DE for the RS-485.
5. A0.2-Q0.2 – If this switch is ON, the DE-RS485 switch must be set to OFF. Being in ON mode
it enables the outputs A0.2-Q0.2.
4. RE-RS485 – If this switch is ON, the A0.1-Q0.1 switch must be set to OFF. Being in ON mode
it enables EE for the RS-485.
3. A0.1-Q0.1 – If this switch is ON, the RE-RS485 switch must be set to OFF. Being in ON mode
it enables the outputs A0.1-Q0.1.
2. SDA-D2/I0.0 – Choosing between SDA (I2C) and I0.0. If this switch is ON, the I0.0 input will
be enabled and the SDA will be disabled. If this switch is OFF, the SDA will be now available
and I0.0 disabled
