AMX Introduces Next Generation of Integration Solutions; New Control System Rewrites the System Integrator's Rulebook.

DALLAS--(BUSINESS WIRE)--June 10, 1999--

AMX Corporation (Nasdaq:AMXX) announced that it will introduce NetLinx(TM), its next generation of Internet integration systems at the INFOCOMM show in Orlando, Fla., June 10-12, 1999.

NetLinx redefines the limits of communication speed and integration capabilities with a wide array of hardware interfaces connected by a high-speed, high bandwidth protocol capable of being transported over a variety of networks.

Based on a 32-bit 70MIPS processor, NetLinx devices communicate with each other and the Internet using ICSP (Internet Control System Protocol), a communications standard developed by AMX. While supporting the breadth of Internet network standards, NetLinx also introduces a control system bus, ICSNet, that is nearly 20 times as fast as its predecessors and AMX's competition. With ICSNet, devices may be connected in star, ring or bus configurations. Far from being a "closed" protocol, ICSP is an open standard and has been adopted by nearly 100 equipment manufacturers. ICSP products can communicate directly to the NetLinx system, eliminating the need for additional interface peripherals. ICSNet uses industry standard Category 5 wiring, while ICSP is a network agnostic protocol, and may be transported over wireless LAN systems, fiber, ATM and IEEE 1394.

AMX President and CEO Joe Hardt: "Over the years, we have seen the application of our products grow from relatively simple individual systems to large-scale integrated networks. It is this need for larger, faster networks that was the inspiration behind NetLinx. Systems are no longer limited to a single central processor and 255 devices; with NetLinx, it is now possible to create networks of thousands of devices sharing the power of multiple inter-networked processors. Most importantly, NetLinx makes it possible to integrate existing systems with this new technology, drawing a path from the present to the future."

NetLinx is available as a modular cardframe system, an integrated controller or as a series of networked modules, and features the same robust construction that made the AXCESS series the most popular control system in the industry. NetLinx masters simultaneously communicate using ICSP over any IP capable network, Axlink and ICSNet. NetLinx masters also bring the Internet directly in by accepting optional PortCards for to Ethernet (100/10 BaseT) or ATM. Additional PortCards to support IEEE 1394, USB, MediaWire and other networking standards will be available in the future. A single NetLinx master supports up to 32,000 devices, and multiple NetLinx systems may be connected, making large-scale integration of offices, campuses, and communities possible. As an IP native device, NetLinx masters allow complete control, information and content integration, and diagnostics of NetLinx systems over the Internet.

When connected to a server PC running WebLinx server software, information systems such as databases, Web servers, mail servers and any other Internet application become ICSP compliant devices and can therefore, integrate and communicate directly with any ICSP device on any NetLinx system. WebLinx also provides complete Web browser integration.

NetLinx is programmed using AMX's Integrated Development Environment, a Windows application based on the AXCESS Level 2 programming language. Programmers already familiar with AXCESS will not need to learn a completely new language to use NetLinx, simplifying the transition.

Scheduled for release in November 1999, NetLinx provides a powerful tool for systems integration. NetLinx will be distributed alongside AMX's AXCESS series control system, providing integrators with new solutions for the most demanding applications.

AMX Corporation, in concert with its wholly owned subsidiary PHAST Corporation, is the worldwide leader in integration network systems, innovations that bring people in touch with their technology. Specialists in the science and art of control, AMX Internet-active systems harness the power of electronic media, mechanics, and information so that technology behaves as a natural extension of our lives.
