VE209S Mesh Controller
Overview
VE209S is a high performance mesh controller which together with a Semtech
SX1211 or
SX1231 transceiver serves as the main building block of a VEmesh node.
VE209S based networks are targeted and optimized for low-power, battery-operated
systems, which operate in the ISM and SRD sub-Giga frequency bands. They use
frequency hopping spread spectrum (FHSS), notable for its resilience to interference.
The mesh controller's network settings and functionality are set by the user to fit the exact needs of their application. These settings are configured using a protocol based on ITU-T V.250 Recommendations and on TIA/EIA 602 A Standard, both rooted in the AT commands.

Reference Design
The support offered by Virtual Extension to its VE209S customers includes
reference designs for various
applications, such as smart metering and lighting.
We provide a reference design example of a VEmesh node used in an Emergency Lighting product and application.
The design provides wireless mesh connectivity used for the remote testing of emergency lighting. This helps ensure the lights works when needed, maintain their certification, and uphold safety regulations. The solution drastically reduces the effort and cost required to test and document the proper
operation of emergency lamps and exit signs.
Ordering Information
VE209S is available in several 20/24-Pin packages and in two temperature ranges.
To order the part, send your inquiry to
sales@virtual-extension.com.
A starter kit that includes several VE209S nodes and a USB gateway is available for testing and integration purposes.
