About the FerIT
The FerIT is a data monitoring, control, and communication device for on-farm applications. It is compatible with Rubicon’s FarmConnect range of products and can be used with Rubicon FarmConnect software to remotely monitor and control both Rubicon products and third-party devices. It is designed to be rugged, easy to install, and easy to use.
The FerIT comes in two configurations:
- The FerIT Node is a low-powered data collection device designed for monitoring applications.
- The FerIT Solar Node is a solar powered device intended for high-power actuation and control. It
contains an integrated FerIT Node and adds the ability to drive devices such as Rubicon’s BladeMeter and BayDrive.
Both the FerIT Node and the FerIT Solar Node can be supplied with either a LORA or a P400 radio connection for communication with a Rubicon Gateway.

Installation
Installation Options
The FerIT Node and the FerIT Solar Node are mounted on a pole using a suitable mounting bracket. You can mount the FerIT to an existing pole, or use the optional star picket or ground screw mounting options. The FerIT should be mounted at least 1.5m off the ground, and above nearby crops or objects where possible.
FerIT Node Installation
The FerIT Node can be connected to a mounting bracket using one of the following options depending on the bracket design:
- Two M5 bolts on the base of the FerIT Node. This is the most common mounting option.
- Two button head bolts on either side of the antenna. Remove the FerIT Node cover to access these mounting screws.

FerIT Solar Node Installation
Battery handling:
Please take care when handling the FerIT Solar Node internal battery. This may be a fire hazard if it is dropped onto a hard surface.
The FerIT Solar Node can be connected to a mounting bracket using one of the following options depending on the bracket design:
- Four M6 bolts on the base of the FerIT Solar Node. Two screw into captive nuts and two must be secured with M6 Nyloc nuts.
- Four M6 bolts on the rear of the FerIT Solar Node.

The FerIT Solar Node includes an integrated solar panel. This must face north in the southern hemisphere and south in the northern hemisphere.
Certification
FerIT Regulatory Requirements
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encourage to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna
- Increase the separation between the equipment and receiver
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help
WARNING: 900MHz Operation:
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 21 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.
