Specifications from the Prolon Tree-Com Wireless Adapter (PL-TREE-COM) datasheet V1 (PL-DATA-TREECOM-EN-V1), reviewed 2026-09-25.
A single root node connects to one or more leaf nodes, and root and leaf nodes can replace wire at any point in the network. The standard daisy-chain bus can still be used where it makes sense, so wireless adapters are only added where they are needed.
Best For
- Networking Prolon devices that are difficult to reach with wire
- Retrofits where running a new RS485 daisy chain is impractical
- Systems that combine wired and wireless segments on a single network
- Crowded 2.4 GHz environments that need interference avoidance

Key Features
Wired and Wireless in One System
Integrates wired and wireless segments into a single system. The standard daisy-chain bus can still be used, keeping the number of adapters to a minimum.
Root and Leaf Topology
A single root node connects to one or more leaf nodes, and nodes can replace wire at any point in the network.
Up to 3,300 ft Range
Maximum distance of 3,300 ft (1,000 m) between wireless devices, line of sight.
Cognitive Coexistence
The Mira 2.4 GHz protocol uses patented adaptive frequency hopping to avoid wireless disturbances in the crowded 2.4 GHz band.
127 Branch IDs
Up to 127 branch IDs can be used on a single network.
Over the Air Updates
Supports over the air updates and is backwards compatible with most Prolon controllers.
ZOT Supply is an authorized distributor of Prolon products.

Frequently Asked Questions
What does the Prolon PL-TREE-COM do?
It is a wireless RS485 converter for the Modbus protocol that wirelessly extends the standard RS485 wired daisy chains used by Prolon HVAC control products, for new buildings and retrofits.
What is the range of the PL-TREE-COM?
A maximum distance of 3,300 ft (1,000 m) between wireless devices, line of sight.
What serial protocol and baud rate does the PL-TREE-COM use?
Modbus RTU over RS485 at 57600 bps.
How are PL-TREE-COM adapters arranged on a network?
A single root node connects to one or more leaf nodes. Root and leaf nodes can replace wire at any point in the network, and up to 127 branch IDs can be used on a single network.
Can wired and wireless segments be mixed?
Yes. The adapter integrates wired and wireless into a single system, and the standard daisy-chain bus can still be used where appropriate.
How does the PL-TREE-COM handle 2.4 GHz interference?
It uses the Mira wireless protocol, whose patented adaptive frequency hopping algorithms, called Cognitive Coexistence, avoid wireless disturbances in the crowded 2.4 GHz band.
What power does the PL-TREE-COM need?
24 VAC ±10%, 50/60 Hz, Class 2, with a consumption of 1.2 VA.
