HX8 GrowNET ™ Hubs allow multiple GrowNET™ sensors, relays and
dosing pumps to be connected to a single LX1 or LX2 interface. Indi-
vidually buffered, full-duplex ports for signal integrity. Hubs can be
daisy chained to form a network of up to 247 devices.
Hubs provide up to 1A of power for operating sensors and some re-
lays directly over the GrowNET cable. A DC jack on the hub provides
24Vdc power to the ports from the included 120V wall power supply.
The default serial data format for the LX2 ModLINK interface is:
19,200 baud, 8-N-1
.
Alternate speeds and formats between 9,600 - 115,200 baud may be configured with the free AgrowLINK PC
utility using a LX1 USB AgrowLINK and the cross-over adapter supplied with the LX2 ModLINK.
