low.
J19
(J20/J21 are not used)
Jumper block: Use the jumper block J19 to set the termination resistor on/off for the
MODBUS communication on the connector J1. For the first and last sensor adapter in
a series, their termination resistors must be set to ON. Use the MC-CS Board with the
default setting because it becomes the "first" adapter in a series.
