RS485 terminating resistor setting
Short circuit the pins 1 and 2 of X1 by short-circuit module,
the terminating resistor of 120Ωis used for RS485 bus;
Short circuit the pins 2 and 3 of X1 by short-circuit module,
the terminating resistor is not used for RS485 bus;
When the short-circuit module is not used, the terminating
resistor is not used for RS485 bus.
