Recommended Wiring Practices
● Order Hood Controllers so that the lowest Hood Controller addresses are connected to Hood
Network Port 1, then Port 2, etc.
● The Touchpad should be the first device in the string from the System Controller.
● When possible, isolate the Touchpad on its own port (simplifies Troubleshooting).
● Last device in each Hood Network String should have the termination resistor switched to ON.
● All wiring is restricted to same room.
Max Number of Hood Controllers
with Optics in Hood Network String
Allowable total cable distance from the System
Controller to the last Hood Network device
1 450 feet
2 200 feet
The System Controller has a limited amount of power output capacity with the included power supply.
Up to (8) Hood Controllers with Optics may be connected across the four Hood Network ports. Also,
each Hood Network Port is power/current-limited. Cable length must be taken into account when
connecting the Hood Controller Network strings. The following table indicates the allowable load
based on maximum cable distance to the respective Hood Network Port.
