The Toshiba-Modbus interface allows full bidirec onal communica on between Toshiba VRF and Digital air condi oner units and Modbus RTU (RS-485) networks. The interface acts as a server device for the installa on, accessing all signals from the air condi oner unit. A wired remote controller can also be part of the network.
Features and benefits
- Modbus RTU (EIA-485) server device The interface acts as a Modbus server device through its Modbus RTU (EIA-485 connector) port.
- Energy savings through a window contact func on This func on helps minimize costs, as HVAC systems are a major building energy consumer.
- AC unit control by both the remote and Modbus RTU The AC unit can be simultaneously controlled by the manufacturer’s remote controller and Modbus RTU.
- Mulple moun ng options Moun ng op ons include DIN rail, wall, or, in some AC models, even inside the indoor unit.
- Dual configura on op ons Configura on is carried out through the interface’s onboard DIP switches and the Modbus interface.
- Total unit control and monitoring from Modbus RTU Through internal variables, running hours counter (for maintenance purposes), and error indica on.
- No external power required The interface is powered directly from the AC unit, so no external power supply is required.

Installation Conditions |
This gateway is designed to be mounted inside an enclosure. If the unit is mounted outside an enclosure, precautions should always be taken to prevent electrostatic discharge to the unit. When working inside an enclosure (e.g., making adjustments, setting switches, etc.), typical anti-static precautions should always be followed before touching the unit. |
