DESCRIPTION
The WBT900-K and WBT900-IP-K transceivers allow you
to install a close or long range, non line-of-sight, point-to-
multipoint, wireless BACnet MSTP or BACnet IP network, at a
fraction of the cost of installation labor, conduit and cable.
The WBT900-K and WBT900-IP-K transceivers are plug
and play, requiring no special programming tools or network
management software.
FEATURES
• 902-928 MHz frequency provides excellent non-line-of-
sight performance to penetrate foliage, building walls,
and floors
• Highest Quality of Service (QoS) available-synchronous
point-to-multipoint protocol enables extremely low data
latency and jitter
• 128 bit encrypted payload protection provides secure
data delivery
• Simple plug-and-play setup with minimal configuration
required
• Flexible input power, 12-24 VAC/DC
• Up to 50 mile range
