Product Overview

This listing is for one genuine Davis Instruments Wireless Repeater with Solar Power, product number 7627.

Davis designed the 7627 to extend the communication range of compatible Davis wireless weather-station systems and to improve reception where distance, walls, structures, terrain, vegetation, or other obstructions reduce the direct radio link.

A properly functioning repeater receives compatible Davis weather-data transmissions and retransmits those signals toward a compatible receiver, console, Weather Envoy, or another repeater. This particular unit is not currently performing that function properly.

Manufacturer Design & Intended Function

According to Davis Instruments, the 7627 is intended for longer wireless transmission distances and for locations where reception is reduced by walls, structures, terrain, vegetation, or other environmental interference.

Davis specifies a maximum radio-link range of approximately 1,000 feet / 300 meters outdoors with clear line of sight, with typical range through walls of approximately 200–400 feet / 60–120 meters.

Compatible systems can use multiple repeaters and transmitter IDs to create larger weather-monitoring networks.

Important: The specifications and design information in this listing describe how a properly functioning Davis 7627 is designed to operate. They do not represent a claim that this particular defective unit currently meets those specifications.

The original packaging for this older repeater states “Compatible With Vantage Pro2 Only.”

Current Davis documentation for product number 7627 lists compatibility with Vantage Pro2, Vantage Vue, and Weather Envoy equipment.

Because this is an older production unit, compatibility can depend on the console, transmitter generation, firmware version, radio frequency, region, and network configuration.

Compatibility should be independently verified by the buyer. Compatibility does not change the fact that this particular repeater has a known communication fault and is being sold for repair/parts.

THIS IS NOT A WI-FI REPEATER This product does not extend household Wi-Fi, cellular service, internet service, Bluetooth, or ordinary computer networking. It was designed specifically for compatible Davis Instruments wireless weather-station equipment. Cosmetic Condition

The white outdoor enclosure remains in generally clean cosmetic condition with ordinary age, storage, and handling marks.

The external antenna is present.

The solar panel appears physically intact with normal light surface marks / storage residue.
