Insert all three jumpers on the unit at the start of network and the unit at the
end of the network. DO NOT insert the jumpers on the intermediate units.

• Jumper P1 adds a 510 ohm polarization resistance between the negative
data line (-) and GND;
• Jumper P2 adds a 120 ohm terminal resistance between the two data
lines (+) and (-);
• Jumper P3 adds a 510 ohm polarization resistance between the positive
data line (+) and the +5 Vdc internal voltage.
