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.

Use the LX2 ModLINK to connect RS-485 MODBUS devices to the GrowNET™ port.

See MODBUS manual for more information.

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.
