Equinox Systems, Inc. was a U.S.-based manufacturer specializing in networking hardware and software development, operating out of Miami, Florida from 1983 until 2000. Originally concentrating on enterprise digital PBX solutions for data communication, the firm transitioned during the 1990s into a leading OEM provider of modems, Ethernet switches, and sophisticated serial communication interface cards. In 2000, Equinox was acquired by Avocent, which continued to operate it as a subsidiary for several subsequent years.
Establishment and Early Years (1983–1985)
Equinox Systems was established in 1983 in Miami-Dade County by Bill Dambrackas, Mark Cole, and Kevin Doren after they opted not to move with their previous employer Racal-Milgo. Supported by an investment of $1.1 million from TA Associates and joined by eight former Racal-Milgo staff members, the company was incorporated in March 1983 and took its name from the March equinox.
The firm introduced its initial offering—a data PBX priced at $30,000—in early 1984. These data PBX units enabled communication between data terminals and minicomputers or peripheral devices and were preferred by organizations operating wide area networks due to their cost-effectiveness and compatibility with legacy systems, despite being gradually overtaken by Ethernet LAN technologies. Equinox deliberately aimed to capture market share from Micom rather than directly challenge Racal-Milgo.
Equinox’s data PBX gained traction among major enterprises such as Intel, Bell South, AT&T, Toys "R" Us, Chase Bank, and Sprint. Although the company secured a $3 million funding round led by Hambrecht & Quist in early 1984 and expanded its customer base significantly, it recorded losses amounting to $432,000 in 1983 and $281,000 in 1984.
Profitability and Expansion Phase (1985–1992)
In 1985, Equinox raised $2.5 million from Oak Investment Partners alongside a $500,000 contribution from Digital Equipment Corporation (DEC), marking the onset of profitable quarters. By March 1986, with a workforce numbering 100 employees, the company increased its headquarters space from 25,000 to 57,000 square feet to accommodate growth. In 1989, Equinox introduced its first Ethernet-enabled products—the ELS-48 terminal server and ELG-48 gateway—utilizing DEC’s Local Area Transport protocol.
After Hurricane Andrew devastated its South Dade facility in August 1992—resulting in $2 million worth of inventory losses and substantial infrastructure damage—Equinox moved operations to Broward County near Racal-Milgo’s location. Thanks to offsite backups of critical data, business operations were maintained without interruption. In October 1992, Encore Computer provided temporary office space in Plantation, Florida that became Equinox’s permanent headquarters. By 1994, the company expanded further by acquiring additional premises formerly occupied by Encore.
Public Offering and Later Challenges (1992–2000)
Equinox postponed going public until March 1993 when it finally completed its initial public offering. Following the IPO price of $11.50 per share, the stock value plummeted to $3.75 by January 1994. Hambrecht & Quist’s holding of 3.9%, initially worth $1.7 million at IPO, declined sharply to $544,000—just above their original $500,000 investment made in 1984. This significant drop led The New York Times to classify Equinox as a high-risk investment during that period.
In February 1995, Equinox announced plans to build a new 45,000-square-foot headquarters on seven acres located in Sunrise, Florida, signaling operational stability with a staff count around 100 employees. The relocation was finalized by early 1997. The company reached its peak performance during the late 1990s with record profits reported between 1997 and 1999 before encountering renewed difficulties entering the year 2000.
Acquisition (2000–2003)
In November 2000, Avocent Corporation, an international provider of data center hardware based in Huntsville, Alabama, declared its intent to purchase Equinox for $57 million. The transaction was completed by January 2001, after which Equinox functioned as a subsidiary under Avocent for a number of years. This strategic acquisition broadened Avocent's range of products and enhanced its presence within the networking and data center sectors.
