Wall mounting slots are provided for installing against a vertical wall surface, or a hanging bracket is avail-
able for conveniently suspending the sensor from a wire or cable in the middle of the environment. Note the
location of the light sensor (top.) Sensor should be installed with the light sensor facing up.
Install in locations with adequate access to the environmental conditions and away from extreme inuences
such as ventilation ducts, doorways, windows or heat generating equipment such as lights and ballasts.
Installation Instructions
Do NOT connect the GrowNET port to Ethernet networks. Disconnect power while making connections to
prevent damage to any components.

Sensors with analog output connect to Agrowtek’s GC-Pro and GC-ProXL controllers using the standard
MINI-DIN 6 analog sensor cable. Power is provided to the sensor through this cable.
Plug the cable rmly into the analog port on the sensor and into the desired sensor port inside the GC-Pro/
XL controller. Sensor ports are located on “modules”inside of the controller. Route sensor cables through the
sensor cable slot on the bottom of the controller.
50ft extension cables are available and may be used to extend up to 1000ft distance from the controller.

Sensor Mapping
Sensors must be “mapped”in the controller so it knows which sensors are connected to the sensor ports.
Each port has four“channels”which must be mapped according to the sensor’s channels.
Controller Channels:
Port 1 = Channels 1-4
Port 2 = Channels 5-8
Port 3 = Channels 9-12
Port 4 = Channels 13-16
Sensor Channels:
Channel A = Temperature
Channel B = Humidity
Channel C = Light
Channel D = Humidity
Example mapping zone 1 climate sensor connected to port#2:
Temperature = 5
Humidity = 6
Light = 7
CO2 = 8 (leave 0 if CO2 sensor is not installed)

Use the LX2 ModLINK to connect MODBUS devices to the GrowNET™ port.
HX8 8-Port Hubs
HX8 GrowNET ™ Hubs allow multiple GrowNET™ sensors, relays and
dosing pumps to be connected to a single LX1 or LX2 interface. Indi-
vidually buered, 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.

Calibration registers are 16-bit signed integers for the purpose of calibrating the sensor values or analog out-
put channels. Calibration may be achieved by writing the desired calibrated value to the associated register.
Writing to the calibration registers automatically invokes the calibration routine for that register.
Oset Calibration
Oset, or zero calibration, is an arithmatic positive or negative correction to the sensor reading and is the
only type of sensor calibration available on climate/environmental sensors.
To perform a sensor oset calibration, simply write the corrected sensor value to the oset calibration reg-
siter (taking into account the integer scale as shown above.)
For example: to set the temperature to a calibrated value of 25°C, write the value“2500.”
Analog Calibration
Analog output calibration sends a positive or negative oset to the respective output channel’s digital to
analog converter (DAC.) The DAC has a resolution of 0.005mA/bit.
±1 calibration bit = ±0.005mA adjustment
For example: to shift the analog output up by 0.1mA, set the analog oest value to +20. ( 0.1 / 0.005 = 20)
Sensor # Type Integer Scale Range
1 Temperature x100 -2000 - 6000 (-20 - 60°C)
2 Humidity x10 0 - 1000 (0 - 100%)
3 Light x1 0 - 1000 W/m2
4CO2 x1 0 - 2000 ppm
For example: an integer temperature value of 2417 is equal to a temperature reading of 24.17°C.
Sensor values are available in integer or oating point formats depending on the register requested (see
map.)
Sensor Value Registers
Calibration Registers
0x03 Read Multiple Registers
0x06 Write Single Register
0x10 Write Multiple Register
Supported Commands
All 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.

CO2 ppm Sensor Upgrade
The SXC sensor may be upgrade to sense and control CO2 ppm with a precision NDIR type CO2 sensor.
1. Disconnect cables from the sensor.
2. Remove the hanging bracket (1).
3. Take note the orientation of the light sensor on the cover.
4. Remove the two cover screws (2) and lift o the cover.
5. Locate the CO2 headers on the circuit board.
6. Position and install the CO2 sensor module (3) ensuring the sensor is oriented with the correct pin head-
ers. One header is 4-pins and the other is 5-pins.
Installing the sensor backwards will damage the CO2 module.
7. Re-install the top cover and re-connect cables.
Note the light sensor orientation is correct and not backwards.
8. Check to ensure the CO2 reading is now working.
Note correct pin alignment.

The fan air lter should be periodically removed for cleaning.
It is NOT necessary to remove the fan.
1. Pry the retaining grate (1) out of the base (3) using a small at blade eye-glass screwdriver.
2. Remove the foam lter (2) and replace, or clean with mild dish detergent and water, then pat dry.
3. Check for proper fan operation while the lter is removed.
If fan is not spinning or is making noise, replace the fan.
4. Re-install the foam lter (2) and grate (1) into the base (3) gently snapping the grate back into place.
