Note: The digital lightLINK must be connected to a LINKS Hub in order to power on and function. Additionally, there must also be a canopyLINK registered to the associated LINKS Hub with a climaLINK sensor connected in order for the high temperature lighting failsafe and no data lighting failsafe to function on the digital lightLINK.

Installation & Wiring Instructions
The digital lightLINK modules connect Growlink HUB to lighting fixtures from various manufacturers that are controlled with digital communication protocols. One module is required per lighting zone and is situated between the controller and the light fixtures as a communication bridge. The digital lightLINK enables full intensity and spectrum control on compatible fixtures from the LINKS system. 
HUB Connection Port: RJ-45 connector port for power & data.
MS/TP Terminals: Terminal blocks for connecting RS485 capable devices.
RJ-12 Connection: RJ-12 connector for dimming lights via the connected RJ-12 cable.
Thinkgrow®
Thinkgrow® fixtures require the ECS-9 Data cable (12ft/ RJ12 to 4-pin IP65 connector
cable) available from Thinkgrow®. This cable plugs directly into the digital lightLINK for
fixture control.
Dutch Light Innovations®
Dutch Light Innovations® (DLI) fixtures require standard RJ-12 phone cables and RJ-12
splitters. This cable plugs directly into the digital lightLINK for fixture control.
Hydrofarm®/Phantom®
Hydrofarm®/Phantom® fixtures that are controlled by the Autopilot series of controllers
have a unique wiring configuration despite using the same RJ-12 connectors as the
previous manufacturers. These fixtures require wiring to the terminal block by cutting
and stripping the wire of the RJ-12 cable.
Scynce®
Scynce® fixtures require the use of the Sycnce® gateway device (THEIA Echo Air.) The
digital lightLINK is connected to the RS-485 MODBUS port on the gateway, and the
gateway is put into remote control mode.
Revolution Lighting®
Revolution Lighting® fixtures use a RJ-11 or RJ-12 cable between fixtures for RS-485
data. Standard RJ-12 couplers allow multiple fixtures to be daisy chained together.
Connection to Revolution Lighting® fixtures requires manually connecting the wires to
the terminal block by cutting and stripping one end of the RJ data cable. See
connection details below.
Fohse®
Fohse® fixtures use various methods and cables depending on the model of fixture.
Circular Connectors (Aries Series)
Fohse® fixtures which have a circular 3-conductor connector are wired as shown below.
Connection to Fohse® fixtures requires manually connecting the wires to the terminal
block by cutting and stripping one end of the Fohse® data cable. See connection
details below.
RJ-12 Connectors (A3i Series)
Fohse® fixtures which have a RJ-12 (6 position) connector are wired as shown below.
Connection to Fohse® fixtures requires manually connecting the wires to the terminal
block by cutting and stripping one end of the Fohse® data cable. See connection
details below.
Iluminar®
Iluminar® fixtures feature a circular connector with three pins for digital data communication. Connection to Iluminar® fixtures requires manually connecting the wires to the terminal block by cutting and stripping one end of the Iluminar® data cable. See connection details below.
Note: If you don’t see a component in the wiring diagram that matches your brand of light, contact the manufacturer.

Mobile App Setup Guide
1) Plug in your Growlink device to power it on. The LED should be blinking blue. If not, hold the SETUP button until status light flashes blue rapidly (12-15 seconds).
2) Download the Growlink app from the Apple App Store, or Google Play Store.
3) Go to portal2.growlink.com/signup or tap the ‘Sign Up’ button at the login page of the Growlink Mobile App to create a Growlink Account:
After creating your account, a verification email will be sent from ‘no-reply@growlink.com’ to the email address set for your newly created account. One must verify your email address in order to utilize your newly created account.
4) Open the Growlink Mobile App and login to your newly created and verified account:
5) Tap the icon of three lines in the top-left of the Mobile App, then tap the Hardware button in the following menu:
6) One can add a controller to an existing room, or tap the ‘+Add’ button in the following page to add a new room to your account. This is the container that will hold the future controller registration:
7) If you are creating a new Room, provide a name for the Room, the Square Footage of the Room, and the Room Type, followed by tapping the 'Create’ Button to finish creating that room:
8) Once an existing room has been selected or a new room has been created, tap the ‘Continue’ button to begin registering the controller to your account:
9) Tap the LINKS button in the following page:
10) Select the ‘Add Devices’ option to add the controller to the specified room:
11) Select the ‘Digital lightLINK’ option in the following menu that populates:
A digital lightLINK cannot be setup as a standalone controller and instead must be connected to a LINKS Hub with a registered canopyLINK and climaLINK sensor connected to it. This is to ensure the digital lightLINK and the LINKS Hub are able to determine the temperature in the room in order to activate its related high temperature lighting failsafe or no data lighting failsafe to protect the plants within the space.
12) In the following screen, select the LINKS Hub you wish to connect the digital lightLINK to:
Connect the digital lightLINK to one of the Hub ports on your LINKS Hub in order for the digital lightLINK to be detected by your LINKS Hub.
13) Once the digital lightLINK has been detected, the app will populate outputs of the digital lightLINK, where you can then specify the manufacturer of the lights being connected to the digital lightLINK. This ensures the digital lightLINK uses the appropriate protocol to communicate with the downstream lights:
14) Once the manufacturer of the lights have been selected and any required fields for the module have been designated, one can tap the ‘Register Device’ button to push that configuration to your newly configured digital lightLINK and paired LINKS Hub.
15) Once successfully connected and configured, the following success message will display. Tap the ‘Add Equipment to this Controller’ to add more hardware to this controller, Tap the ‘Edit Controller Profile’ button to update the Controller Profile Settings, or tap the ‘Go to Room Dashboard’ button to view the dashboard for the newly connected controller:
Troubleshooting
Controller not showing up on my list of devices to connect:
Check your phone or tablet and ensure Bluetooth is enabled.
Hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Then refresh the device list on your phone or tablet.
Unplug the unit for 10 seconds and then plug the device back in and wait for the LED lights to stop changing colors (typically 15 seconds). Then refresh the device list on your phone or tablet.
Controller didn’t connect to Wi-Fi:
If unsuccessful in the first attempt to connect the controller to the Wi-Fi network, hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Once rapid flashing becomes visible, immediately release the Setup button. This will put the controller into Listening Mode (Blinking Blue). Now, restart the connection process outlined in the Quick Setup Guide section above.
The Wi-Fi network being used has changed:
In the event the controller needs to re-connect to an existing or new Wi-Fi network, put the controller back into Listening Mode (see above) and follow the Controller Connection process outlined in the Quick Setup Guide section above.
