There are four main sections to the system:
The EnviroMon Network
The network is a four-wire cable that carries power and data between the logger, converters and optional equipment like remote alarms. The logger can be attached anywhere along the network cable.
For most applications, low cost telephone style cable is used. This allows operation with 400 meters of network cable between the logger and the furthest sensor. With thicker cable, this distance can be increased to a kilometer or more.
Cables can be purchased in standard lengths, alternatively you can make up your own.
