LTX-VCI Datasheet Issue 1.05.01 12/07/2003 Doc No. 92101
1.1 LTX-VCI Features
• Provides a common control interface for many of the major brands of package Air-
conditioning units
• Simplifies the monitoring and control of large numbers of A/C units
• Allows the monitoring and control of air-conditioning units from range of conventional and
LonWorks Building Management Systems
• Provides backwards compatibility with existing RealTime BMS controllers and interfaces
• Provides a practical interface for managing thousands of network variables without the
need for large numbers of bindings, and the ability to rezone the system without rebinding
1.2 Description
The LTX-VCI expands RealTime air-conditioning controls functionality to allow interfacing with
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 following table provides the range of existing coverage for RealTime controllers and
shows which solutions at present require the addition of the VCI. The range of solutions is
constantly expanding, the latest solutions are available from the RealTime web site.

LTX-VCI Interface Required - YES YES
Native A/C Interface LG1 L-Gateway LMAP
The LTX-VCI can handle A/C interfaces with up to 64 indoor units. Many LTX controllers are
only designed to handle 16 units, therefore the VCI can serve data to up to 4 LTX controllers in
order to allow access and control of all units.
Interfaces that the LTX-VCI are compatible with are associated with a
Device Interface Sheet
within this datasheet that describes specific details of interfacing, lists what functionality is
available and provides fault code references. The current version of the LTX-VCI is compatible
with the following device interfaces:
