RS- 485 Switch configuration
RS-485 TOP ZONE: In order to enable the RS-485 protocol the TOP ZONE must be
configured as it is shown in the table.
Although the switch serigraphy is only referenced to RS-485.
Having this setup, the I0.3 & I0.2 are disabled
RS-485 LEFT ZONE: In order to enable the RS-485 communication
protocol it is necessary that the switches of the left zone are
configured as it is showed in the table.
The ones marked with “-“ mean that they don’t affect the RS-485
communication protocol
I2C Switch configuration
I2C: Enable SCL and SDA connections (direct Arduino pins) with configuration switches. I0.0
and Q0.6 will not be available. In order to implement this communication a 4.7kΩ pull-up
resistor
(IS.ACI2C-4.7K
)
is required.
