ADDRESSABLE AND MULTI-SENSOR NODES
2.1 GEONET ADDRESSABLE SENSOR NODES
The GeoNet 8800-XX-ADR-CBL addressable sensor node enables your network
to communicate with addressable sensors, such as 6150F Addressable MEMS
strings. See the figure below.

Addressable sensor nodes function in the same manner as other nodes. Install
these using the instructions in Section 3.
2.2 GEONET MULTI-CHANNEL NODES
The GeoNet Multi-Channel Node (MCN) increases the number of sensors a node
can read, as indicated in the following table.
Model
8800‑XX‑04C‑CBL
8800‑XX‑08C‑CBL
TABLE 4: Multi-Channel Node Sensor/Load Limits
Channel switching is controlled by the node and is accomplished by solid-state
(non-mechanical) circuitry.
Each MCN uses as much data as four or eight single nodes, depending on the
node model. The MCN is protected from environmental contaminants by a
rugged IP66 die cast aluminum enclosure. An earth ground terminal is provided
on the exterior of the enclosure to protect against lightning and other large,
transient voltages.
MCNs can ship with the following accessories:
■
One omni-directional antenna (2.1 dBi). For other antenna options, please
contact
■
Two D cell alkaline batteries
■
Four desiccant packs
