To wire a laptop to the L W
ON ORKS
1. Remove the front plate of the EC-Sensor.
2. Connect all three (3) LON cables coming from the previous device, going to the next device and going to the EC-Sensor to the LON1 and LON2 input
terminals on the controller. If inserting multiple wires in the terminals, ensure to properly twist wires together prior to inserting them in the terminal con-
nectors.
3. Connect the LON network cable coming from the controller to the NET+ and NET- terminals on the EC-Sensor.
4. Connect the two (2) wires that terminate with the ⅛" audio cable to the output terminals of the LonTalk
5. Insert the ⅛" audio cable into the communications jack of the EC-Sensor.

If the distance between the EC-Sensor and the controller (T-tap length) is greater than 10ft (3m), a bus topology must be used. The following figure
shows how the EC-Sensor in bus topology LON network:
