Installation Instructions
DANGER Electrocution Hazard
Always un-plug the relay module before servicing or wiring; ensure all power
is disconnected. For continued protection against electric shock plug into
grounded outlets only and do not remove the ground pin. Install all electrical
equipment and wiring in accordance with national and local electric codes.
For indoor use in dry locations only (0-80% RH non-condensing.) Do not open
the relay; there are no user-serviceable parts inside.
General Notes:
- Install into a vertical receptacle with the RJ45 connection facing down to maintain enclosure rating.
- Device is not intended for use with an extension cord.
- For indoor use and installation only.
Mounting the RX1i Relay
The RX1i intelligent relay is designed to be plugged into a standard 120Vac
wall outlet mounted on a vertical wall surface.
A screw tab is provided which can be used to fix the relay to the wall outlet
preventing accidental disconnection from the receptacle.
Equipment to be controlled is then plugged into the outlet on the RX1i. When
the RX1i is activated, power will be switched to the outlet on the RX1i from
the wall outlet.
NOTICE:
Plug the relay fully flush into a wall receptacle.
Do not plug the relay into an extension cord.
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.

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.
Connection to USB AgrowLINK
LX1 USB AgrowLINK connects Agrowtek’s devices to a computer’s USB port for:
- Firmware Updates
- Manual Operation
- API Based Control
- More
Agrowtek’s intelligent relays may be connected to the LX1 USB AgrowLINK for firmware updates, communication protocol configuration, addressing and manual operation. Standard drivers automatically install in Windows for the LX1 USB AgrowLINK.
Connection to MODBUS RTU
RS-485 / RS-422
Use the LX2 ModLINK to connect MODBUS devices to the GrowNET™ port.
3.3/5Vdc Serial Bus Compatible.
Include required bus terminating resistors per EIA standard.
Serial Speed & Format
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.
See MODBUS manual for more information.
Supported Commands
0x01 Read Coils
0x03 Read Multiple Registers
0x05 Write Single Coil
0x06 Write Single Register
A request to use a function that is not available will return an illegal
function exception.
Register Types
Data registers are 16 bits wide with addresses using the standard MODICON
protocol. Floating point values use the standard IEEE 32-bit format occupying
two contiguous 16 bit registers. ASCII values are stored with two characters
(bytes) per register in hexadecimal format. Coil registers are single bit
values which control and indicate the status of a relay; 1 being on and 0
being off.

Technical Information
Troubleshooting
Relays are not activating, no power LED on PCB
Ensure the relay is plugged into 120VAC outlet and the power is on to the
outlet.
Relays are clicking but no power to an outlet
Check the status LED to determine if AC power is reaching the line terminal of
the receptacle. The red LED is powered by AC voltage from the line voltage
terminal of the receptacle and will only illuminate if voltage is passed
through the relay to the terminal. If the status LED for the receptacle is on,
check the equipment by bypassing the relay.
Maintenance & Service
Exterior Cleaning
Exterior may be wiped with a damp cloth wish mild dish detergent, then wiped
dry. Disconnect power before cleaning the enclosure to prevent electrical
shock.
Fuse Replacement
There are no fuses or servicable components inside the RX1i. Do not open the
enclosure.
