Line Termination – End of Line Resistor

The MRS-485 and DVP-485B adapters are wired in the standard 2W-Modbus circuit definition with selectable built-in
terminating resistors at the ends of the RS-485 bus. The MRS-485 and DVP-485B adapters provide integral
termination for the end of line resistors (EOL). The terminations use 4-pin connector (for MRS-485) and 3-pin (for
DVP-485B) with a jumper to select termination: The user selects no termination or one of the two Modbus line
termination options. The MRS-485 has two-line termination options provided and DVP-485B adapters have 120-ohm
termination options provided onboard.

Place the EOL jumper on one of the following positions:
