DLG Headquarters

Following many years of cooperative research & development work in data transfer for industrial applications, DATA-LINC GROUP introduced its first product, the Power Line Carrier Modem (LCM100), in the mid 1980s. The company went on to develop the DOVE, Data Over Voice Encoder, which simultaneously carried voice and digital data over phone lines. Since 1988 the company has expanded it’s product line with a major focus on spread spectrum frequency hopping license-free radio modems and have become the manufacturer of the broadest line of industrial-grade modems in the world. A list of products include spread spectrum Wireless Ethernet, Serial & Digital I/O modems, direct sequence high-speed industrial Wi-Fi complaint 802.11b/g modems, and Wired data-communication peripherals and systems.
