This manual covers basic GroWeather/EnviroMonitor installation, including
how to connect your sensors to the sensor interface module (SIM) and how to
power your unit. Instructions on installing/mounting sensors and other system components (such as the Alarm Output Module) are contained in the manuals for those products. This manual does include several installation drawings
which depict typical GroWeather/EnviroMonitor installations and should help
you connect all of your components correctly.

We have provided two sheets of labels which should aid you in your installation. The majority of the labels on the sheets are cable labels for marking the
ends of each cable. These labels contain connector codes which will help you
attach the correct cable to the correct connector. We have included two label
sheets so you can label both ends of each cable with the same label.
Note: Also included on the label sheet are circuit board labels which are for use only with industrial
versions of the stations.
Cable Connector Codes
To simplify installation, we have coded each connector and included the code
on the cable label and on the circuit board or enclosure next to the appropriate
connector. Most connector codes includes a letter and a number. The letter
identifies the module or unit on which the connector is located while the number identifies the specific connector. The following letter codes identify the
module/unit on which a connector is located.
✦
S = Sensor Interface Module
✦
P = Power
✦
C = Console
✦
L = WeatherLink

B = Battery and Solar Power

A = Alarm Output Module

Labeling Cables
Any installation is going to include a number of cables running from various
sensors and components to other components. To alleviate confusion, we have
included label sheets which you should use to mark your cables (see “Cable
Connector Codes” on page 2).Before you begin installation, lay out all of your
cables and attach the appropriate label to each end of each cable. Make sure
you label every cable end, including extension cables. Doing this now will help
prevent confusion during the installation and if you ever need to disconnect a
sensor/component at a later date.
When labeling cables, orient the label so the connector code nearest the end of
the cable matches the connector to which that end of the cable will be attached.
For example, place one C2/SENSOR I’FACE/S7 label onto the 8-conductor
cable (which will be running between the sensor interface module (SIM) and
the console) so the C2 side of the label is nearest the end of the cable which will
be connected to the console. Place the second C2/SENSOR I’FACE/S7 label
onto the other end of the cable so the S7 side of the label is closest to the SIM
end of the cable.

Temperature Sensor/Probe Labels
There are two labels (TEMP/S2 and TEMP2/S3) for the external temperature
sensor/stainless steel temperature probe because you may connect this sensor
in one of two locations (connector S2 or S3). Consult the guidelines below to
decide which label to use on your external temperature sensor/stainless steel
temperature probe. Note that you should always use the T-HUM/S2 label on
your external temperature/humidity sensor.
✦
If you have a temperature/humidity sensor connected to the system, and want to
use the external temperature sensor/stainless steel temperature probe as the
“soil” temperature sensor, use the TEMP 2/S3 label.
✦
If you do not have a temperature/humidity sensor and want to use the external
temperature sensor/stainless steel temperature probe as your primary outside
temperature sensor, use the TEMP/S2 label.
✦
If you have a UV sensor (which needs to be attached at connector S3) and either
the external temperature sensor or the stainless steel temperature probe, use the
TEMP/S2 label.
✦
If you have both an external temperature sensor and a stainless steel temperature probe (or two of either), place the TEMP/S2 label on the sensor you are going
to use as the primary outside temperature sensor. Place the TEMP2/S3 label on
the sensor you are going to use as the “soil” temperature sensor.

You may mount the SIM on a wall or other vertical surface or you may simply
set it down on a horizontal surface. It should be sheltered from weather and
located near a grounding point. You may use our Complete System Shelter
(#7724) or Multi-Purpose Shelter (#7728) to provide protection from weather.
Use our Grounding Kit (#7780) if suitable ground is not otherwise available.
1. Remove the cover by pushing down on the tabs at the top until you can remove the
tabs from the slots.

2. If you plan to mount the SIM against a wall or other vertical surface, attach the base
to the mounting surface using the #6 x 1" screws. Otherwise skip this step.
Use two screws (as shown below) when attaching to a stud. Use three
screws (as shown below) in any other case. Drill pilot holes using a #36
(.106" or 2.5 mm) drill bit.

Make sure that you install your sensors and run all necessary cables to the SIM
location before connecting cables to the SIM.
Connecting to the Sensor Interface Module
1. Attach one end of the 8-conductor cable (which runs from the SIM to the console) to
connector S7.
2. Attach the sensor cables to the appropriate connector as shown below.

You may attach either the external temperature sensor, external temperature/humidity sensor, or the stainless steel temperature probe to
connector S2. The sensor connected at S2 will measure outside/air temperature (and humidity if applicable).
You may attach either the external temperature sensor, stainless steel temperature probe, leaf wetness sensor, or the UV sensor to connector S3. The
sensor connected at S3 will measure soil temperature (GroWeather), Leaf
Wetness (GroWeather), or UV (Energy EnviroMonitor).

3. Connect the spade lug on the ground wire to the GND terminal at JP1.
You need to ground the SIM to take advantage of RFI and surge suppression
capabilities.

Routing Cables out of Sensor Interface Module
1. Gather the cables connected on the left of the SIM (including the ground wire) and
secure them to the cable tie lug using a cable tie.
Even if you have only one cable, secure it to provide strain relief. When
tightening the cable tie, make sure the cables are on top of the lug.

In order to connect cables to the console, you must remove the mounting base
which comes attached to the console. To remove the mounting base, press
down on the large tab until it is free from its slot and pull the base away from
the console.
To connect the console to the SIM (or the ICAM), run the 8-conductor cable to
the console and plug it into the jack marked C2 (To Sensor I’face) on the underside of the console.
Primary Power
The console is powered by 9- to 12-volt DC (direct current). In North America,
the power adapter included with your unit converts 120-volt, 60-Hz AC (alternating current) to 9–volt DC, allowing you to run the unit on ordinary household current. If you are outside North America, in a location where the line
voltage is not 120–volt, 60–Hz, check to see if your local dealer has supplied a
power adapter that is appropriate for your electrical power before you connect
the power adapter to the console. If not, you must use a power converter/
transformer or the appropriate power adapter (9-12-volt, 2.5-mm female plug).
To power the console, simply connect the power adapter to the jack marked
C1 (Power) on the underside of the console. Plug the other end of the power
adapter into an appropriate power outlet. Once connected, the console should
run through a brief self-test procedur e. All of the display segments appear, and
the console beeps twice (three times if you have the WeatherLink hardware
module attached). When the self-test finishes, the time (reading 12:00 a.m.)
appears on the display.
