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 Q0.9, Q0.8 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 Q0.9, Q0.8 the jumper must be connected to the
pins 4 and 8. So Q0.9 must be connected with D4 and Q0.8
must be connected to D8.
*The jumpers that are not connected to the middle jumpers MUST NOT be Connected
anywhere.
