EOL Resistor
2-digit Dip-switch S20 is used for setting EOL resistor of RS485.

1 and 2On:Internal EOL resistor is connected
1 and 2Off:Internal EOL resistor is disconnected

For RS485 Class A, loop mode, no EOL resistor is needed.
For RS485 Class B, stub mode, internal EOL resistor of the repeater display at the end of RS485 must be connected.
