Perform crossover wiring.
For crossover wiring of a shielded cable using the terminal SG,
set the terminal 2/SG selector switch to the right side (ON) to
change over the terminal 2 to the terminal SG.
(By this setting, analog inputs to the terminal 2 become invalid.)
When connecting a 100 terminal resistor,
set the switch to the "100 " side.
