Data-Linc Group's broad line of data communication devices includes dial-up/leased line and leasedline modems. Data-Linc Group’s wide selection of products (Also see our license-free wireless— serial, Ethernet, protocol to I/O, I/O to I/O and 802.11b) offers the capability to design hybrid systems to address your specific, unique industrial automation needs, from a simple, single point remote network to a complex multi-tier, multi-drop SCADA system.

Data Transmission Rate
Data-Linc modems provide exceptional data rates, data transmission range and the highest degree of data integrity for PC, PLC and SCADA systems, even in the harshest industrial environments. Our wire modem speeds range from 1200 baud up to 19.2 Kbaud depending upon the lines and type of modem used. If your project requires reliable data transfer our speed and fast turn-around time ensure your data gets through— Data-Linc modems provide the industrial automation solution.

Exceptional Range
Data-Linc wire modems transmit data up to 20,000 feet (6.1 km) on two wire and up to 40,000 feet (12.2 km) on four wire lines; up to 20 miles on unloaded lines, unlimited for loaded lines and dial-up applications; and up to 5,000 feet (1.52 km) on power lines. All of Data-Linc's modems have features that make them ideal for industrial automation and the toughest of SCADA applications.

Data Integrity/Reliability

Data-Linc utilizes only the most robust data communications technologies to provide exceptional resistance to potential data communications problems. Our range of options includes advanced frequency hopping spread spectrum (FHSS) technology for unlicensed wireless data transmission, as well as dial-up and leased line technology for data communication. Data-Linc specialty wire industrial modems can superimpose data on in-company PBX telephone wires without interfering with simultaneous transmission of voice or instrumentation signals.

Our products provides point-to-point and multi-tier, multi-drop data communications and polling/addressing. Most of Data-Linc modems, peripherals and systems operate in an extended temperature range of -40°C to +85°C (-40°F to +185°F) to further assure exceptional data reliability and integrity making them the ideal choice for the automation industry's SCADA systems that must reliably perform in the harshest of industrial environments.

Simple Installation
Data-Linc Group's products support most synchronous protocols used in typical SCADA applications and interface seamlessly with the automation industry’s major PLC SCADA equipment. All Data-Linc modems and cables are factory configured for each application— installation requires no modem field settings, programming or adapters on the part of the user. Thus Data-Linc
modems are easy to install.

Your First Choice for Robust, Reliable Data Communication
When unique SCADA or other data communication needs arise, Data-Linc modems are the industrial automation data transfer solution— well known for exceptional data rates, data transmission ranges and data integrity even in the harshest industrial environments.
