BMS Interfaces

LTX-51 Modbus to LonWorks A/C Interface

The LTX-51 is the first of a range of Modbus to LonWorks Gateways designed for interfacing conventional BMS control systems with LonWorks based systems. The LTX-51 is a BMS interface for controlling air-conditioning units. The interface provides a wide range of functionality including indivual and master/slave control of units, local user control and unit temperature and fault code feedback. Compatable with Toshiba RAV products using the Toshiba LG1 and RealTime LRC-LG interfaces. Compatible with Mitsubishi, Daikin and Hitachi systems using the RealTime LTX-VCI.

The LTX-51 is compatible with any BMS control system with a suitable Modbus interface, systems tested include products from manufacturers including Satchwell, Landis & Staefa/Siemens, Andover, Cylon and Crestron for other manufacturers please contact RealTime for details.

LTX-21 BMS-A/C Interface

LonWorks to BMS Gateway for integrating package air-conditioning units with Trend Building Management Systems. Provides control of individual units and groups, software master/slave groupings and feedback of unit fault codes and temperatures. Compatable with all Toshiba RAV products using the Toshiba LG1 and RealTime LRC-LG interfaces. Compatible with Mitsubishi, Daikin and Hitachi systems using the RealTime LTX-VCI.

LTX-VCI A/C Interface

The RealTime LTX-VCI extends RealTime air-conditioning control solutions by providing a compatible interface to a range of air-conditioning manufacturers. The LTX-VCI acts as virtual interface that allows the existing range of RealTime air-conditioning BMS interfaces and LonWorks Controllers to be instantly compatible with additional air-conditioning manufacturers products. The LTX-VCI v1.05 is compatible with the following interfaces.

The VCI provides the necessary functionality to control individual A/C units as well as return fault and temperature readback data from each unit in a format compatible with existing RealTime BMS control solutions. The VCI can handle manufacturer interfaces with up to 64 units.
