Troubleshooting

How to install the bus

(refer to bus installation schematic)

1. wire the bus with the suggested cable;

2. leave a 10”loop out of the wall at each location

3. cut the loop

4. Skin all 8 wires (2x4) and join each color-like wires

Bus checking

1. at the extremity of the bus cable to be connected to the central controller, skin all 4 wires and

measure resistance between the two wires of the same pair and between a wire of each pair. In

each of these two cases, resistance should be infinite.

2. then, still at the end of the bus to be connected to CARDIO, short wires of each pair and measure

the resistance at the other end, that to be connected to the last item on the bus: resistance should

be NIL.

3. the test is now complete. Remove shorts on the CARDIO end of the bus and leave all 4 wires

open and ready to be connected to CARDIO later on.

!WARNING!: Make sure to remove all short circuits..

Peripheral items checking

During its countdown, CARDIO checks and displays all peripheral products on the bus. Make sure

that it does read all products that have been installed.

Bus polarity

For all products, make sure to respect COM A and COM B:

• the green wire goes to COM A

• and the yellow wire goes to COM B.
