Page 2: Tools And Materials Needed
System Installation OOLS AND ATERIALS In addition to the components listed above, you may need some of the follow- ing tools and materials. Please be sure you have everything you need before beginning the installation. Medium-sized Phillips Screwdriver 9-volt Alkaline Battery Drill with #36 (.106”... - Page 3 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.
- Page 4 System Installation 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.
- Page 5 ONNECTING TO THE 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 Terminal Blocks The industrial GroWeather/EnviroMonitor uses terminal blocks containing high-reliability stainless steel spring-loaded cage clamps. You will be placing one or two wires into each terminal in order to make the connection.
- Page 6 System Installation 2. Attach the sensor cables to the appropriate terminals (as shown below) using the wire colors printed on the circuit board. The drain wire (the uninsulated shield wire) from each cable con- nects to the terminal with the triangle next to it. When using an extension cable, any extra conductors which are not used at the sensor cable-to-extension cable connection should be clipped off to avoid problems at any subsequent connections.
- Page 7 3. Connect the spade lug on one of the ground wires to the Shield Ground terminal and the spade lug on the other ground wire to the Circuit Ground terminal. You will need to connect the ground wires to a suitable ground after you finish installation. Attaching the ground wire to the Shield Ground terminal is optional, though it does allow you to take advantage of the SIM’s RFI and surge sup- pression capabilities.
- Page 8 System Installation 2. Gather the cables connected on the right 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.
- Page 9 Battery Backup We recommend that you also install a 9–volt alkaline battery as a backup power supply. In the event of a power outage, the battery will power the con- sole. Not only will this prevent the loss of data stored by the console, it will allow you to continue observing weather conditions during the power outage.

Page 10: Displaying The Console
Selecting a Site for the Console Unless you use Davis’ Complete System Shelter or a similar weather-proof shelter, you should locate the console indoors. For more accurate readings, fol- low these suggestions. - Page 11 “ Vertical” Orientation Use this mounting base orientation if the console’s LCD will be at or above eye level once the console is positioned. Attach the mounting base as shown below and then place the console onto any flat surface. To Display the Console on a Wall If you want to attach the console to a wall, follow the instructions below.

SRM Pair is connected to a free serial port on your computer. The SRM Pair is connected using a 2-twisted pair cable (Davis Product #7884) which is not included. Using 22 AWG cable, you may run up to 4 miles of cable between the SRM Pair. - Page 13 Alarm Output Module Connected to Sensor Interface Module The illustration below shows an Alarm Output Module (AOM) connection made at the Sensor Interface Module (SIM). The AOM connects to the SIM using the provided 2’ AOM Cable or a 40’ (12 m) Standard 6-Conductor Exten- sion Cable.
- Page 14 System Installation Alarm Output Module Connected to Interface Cable Adapter Module The illustration below shows an Alarm Output Module (AOM) connection made at the Interface Cable Adapter Module (ICAM). The AOM connection must be made using either the 2’ AOM Cable or a 40’ (12 m) Standard 6-Con- ductor Extension Cable.
- Page 15 Using Power Y-Cable to Power Console and AOM It is possible to use a power Y-cable to provide power to both the console and the AOM using a single AC-power adapter, as shown below. The power Y-cable is provided with the AOM. Industrial System Installation Manual SING OWER...
- Page 16 System Installation Field System Installation The illustration on the following page shows an example of an installation in which the sensor interface module is placed outside (using the Multi-Purpose Shelter for protection) and a single cable is run from the SIM to the console, which is located indoors.

- Page 18 System Installation Field System with AC Power The illustration below shows an installation in which the console is located with the SIM (and, optionally, the AOM) in the field near the sensors. The con- sole and modules are housed in the Complete System Shelter (CSS). The Com- plete-System-Shelter Heater might also be included.
- Page 19 Field System with Wired DC Power This system configuration has the same characteristics and advantages as those of the AC-powered system described in “Field System with AC Power” on page 18. In this case AC power is not wired to the site. Rather, the power adapter is plugged into an available circuit in a sheltered location, and the (nominal) 12-Volt DC output is supplied to the station with a two-wire cable (twisted-pair is preferred, but not required).
- Page 20 System Installation Solar-Powered Field System The illustration below shows an installation in which the Complete System Shelter (CSS) houses the console, a battery, and the charging regulator. As shown in “Field System with AC Power” on page 18, data may transmitted via Link cable, read visually from the display, or uploaded to a computer brought to the site.
- Page 21 Solar-Powered Field System with Radio The illustration below shows a solar-powered system (see “Solar-Powered Field System” on page 20) in which the WeatherLink commands and data are communicated via a user-supplied radio. The 1200- or 2400-baud WeatherLink is compatible with any transparent communications channel. Because the solar panel and battery of the Solar Power Kit are not sufficient to supply the radio for continuous operation, the Alarm Output Module is used to switch on power to the transmitter for short scheduled periods.
- Page 22 System Installation “Outbuilding” System Configuration This variation of the “Field System Installation” (page 16) places the console and WeatherLink in a barn or other shelter and then uses a Short-Range Modem Pair (or radio) to communicate with the computer at the “central” site. The figure below shows the use of Surge Protectors (optional) on the SIM-to- console and WeatherLink cables.
- Page 23 “Outbuilding” System Configuration with ICAM and AOM The figure below shows an “outbuilding” system configuration with the addi- tion of an Interface Cable Adapter Module and Alarm Output Module, enabling the weather station, the user, or a computer program to provide inputs to controllers of heaters, fans, motors, or other equipment in the vicinity of the barn or shelter.
