Connection to GrowControl™ GCX

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.

Refer to the GCX controller manual for details on adding the device to the system.

GrowNET™ Hubs

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.

Installation Notes

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.

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.
