Principle Features and Benefits

• Rack mount versions of some Data-Linc Modems (license free wireless, FSK wire and dial-up/leased line) are available, housed in the Schneider Electric Quantum or Compact 984 enclosures, providing chassis mount capability. When rack mount modems are not required, stand-alone metal enclosures with mounting flanges provide physical environment protection and EMI/RFI immunity.
• Data-Linc Modems and connecting cables are factory configured for each  application, assuring a trouble-free installation (no modem field settings, programming or adapters required).
• Wireless Full Duplex, uncompressed data rates to 115.2 Kbaud. Distance to 90 miles. Operating temperatures from -40°C to +75°C (-40°F to 167°F). Dial-up/Leased Line from -40°C to +85°C (-40°F to +185°F).
• Data-Linc modems support point-to-point, multi-point and multi-tier/multi-drop applications.
• Data-Linc employs only the most robust communications technologies to assure exceptional data communications reliability and integrity for data acquisition, control and SCADA applications:
  • Frequency hopping spread spectrum wireless technology (902-928 MHz and 2.4-2.4835 GHz license free bands available) has exceptional immunity to interference and data transmission problems.
  • Frequency Shift Key (FSK) technology provides a high level of immunity to data transmission problems, providing the highest possible data reliability over any two conductor wire, shielded or unshielded, twisted or untwisted (No ground loop or shifting ground plane problems as well as immunity to EMI, noise and surge).

• Ability to transmit data across slip rings, sliding contacts, rolling wheels, shoes, brushes and conductor bars.

• The Data-Linc MDL500 Series of FSK wire modems can even superimpose data on in-plant facility wiring, including AC/DC power lines, PBX telephone wires and instrument loop lines (simultaneously, without interfering with the current, voice or instrumentation signals being transmitted) thereby eliminating the time and expense of data cable installation.

Data-Linc utilizes the most advanced Frequency Hopping Spread Spectrum technology supporting serial and Ethernet connectivity for wireless data transmission (no site license required) as well as, specialized Frequency Shift Key (FSK) techniques for data communications on any two conductor wire. Data-Linc provides the ultimate in data reliability and integrity while also achieving superior performance, user friendly ease of installation and insurance against potential operational problems.
