GrowNET™ Hubs
All GrowNET™ devices are connected using standard CAT5 Ethernet cable with RJ-45 connections.
Devices can be connected directly to the GrowNET™ ports on the bottom of the controller, or through HX8
GrowNET™ hubs. It is typical to simplify cabling by locating hubs centrally in hall ways and rooms allowing
single runs from an 8-port device hub back to a central hub or back to the controller.
HX8 GrowNET ™ hubs expand a single port into eight more ports.
Hubs can be daisy-chained to form a network of up to 100 devices per
GrowNET™ bus. Individually buffered port transcievers provide excellent
signal integrity and extended communication strength and range.
Hubs provide up to 1A of power for operating sensors and most relays
directly over the CAT5 cable. A DC jack on the hub provides 24Vdc power
to the ports from the included wall power supply. A terminal block
power option is also available.
DIELECTRIC GREASE
Dielectric grease is recommended on RJ-45 GrowNET™ connections when used in humid environments.
Place a small amount of grease onto the RJ-45 plug contacts before inserting into the GrowNET™ port.
Non-conductive grease is designed to prevent corrosion from moisture in electrical connectors.
• Loctite LB 8423
• Dupont Molykote 4/5
• CRC 05105 Di-Electric Grease
• Super Lube 91016 Silicone Dielectric Grease
• Other Silicone or Lithium based insulating grease
NOTICE
GrowNET™ ports use standard RJ-45 connections but are NOT compatible the Ethernet network equipment.
Do not connect GrowNET™ ports to Ethernet ports or network switch gear.
Installation Notes
Refer to the GCX controller manual for details on adding the device to the system.
