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.
9. Jumper Configuration
General Jumper Configuration
This jumper makes the choosing between connecting MAX232 to pins
0,1 of the Arduino Leonardo or with the MAX485. In order to use the
RS-232 Hardware Serial protocol both RS-232 must be connected to the
D1/D0. In order to use the RS-485 Hardware Serial protocol both
RS-485 must be connected to the D1/D0.
This jumper zone makes the choosing between connecting the inputs
I0.2, I0.3 to pins 4 and 8 of the Arduino Leonardo respectively, or
connect the RS-232 ports to activate the Software Serial RS-232. In
order to use the inputs I0.2,I0.3 the jumper must be connected to the
pins 4 and 8. So I0.2 must be connected with D4 and I0.3 must be
connected to D8.
*The jumpers that are not connected to the middle jumpers MUST NOT be Connected anywhere.
