9 Jumper configuration
9.1 General jumper configuration
This jumper zone makes the selection between using the RS-485 Full
Duplex or the Analog Outputs. If it is wanted to use the RS-485 Full
Duplex communication protocol the Y+ must be connected to ENABLE,
and Z- also connected to ENABLE. If it is wanted to use the Analog
Outputs, The A0.0 must be connected to ENABLE, and A0.1 also
connected to Enable
This jumper zone makes the choosing between connecting the inputs
I0.2, I0.3 to pins 4, 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 4,8. So
I0.2 must be connected with D4 and I0.3 must be connected to D8.
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.
*The jumpers that are not connected to the middle jumpers MUST NOT be connected anywhere.
