NOTE
Where an RS-232/RS-422 converter is used, R1 is not applicable
since it is built in to the converter.
Use a shielded, 0.33 mm 2 /22 AWG twisted pair cable for each
communication link; terminate the ends of multi-drop line with 200-500
Ohm resistors. Connect the cable shield to the ground input.
