Wired Modems


The Data-Linc Group LLM1100 is a Bell 202 (CCITT V.23 optional) 1200 baud modem. It can be easily configured for simplex (bit mode), half-duplex and full-duplex operations. The LLM1100 is designed to be used on private, leased non-switched telephone lines or any dedicated two-conductor wire (twisted or untwisted, shielded, or unshielded)

Why DATA-LINC wired modems?

Versality & Outstanding performance

Data-Linc Group‘s leased-line modems 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,  and  data transmission range 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. 

Data integrity & Reliability

Data-Linc utilizes only the most robust data communications technologies to provide exceptional resistance to potential data communications problems. This includes advanced Frequency Hopping Spread Spectrum (FHSS) , OFDM (Orthoganol Frequency Division Multiplexing) and Direct Sequence Spread Spectrum 802.11b/g technologies.  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 Installations

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. For your convenience, all Data-Linc modems and cables are factory configured so installation is easy, and because Data-Linc partners with the major industrial automation companies, our modems interface seamlessly with automation industries’ PCs, PLCs and other SCADA equipment. For industrial automation applications requiring data transfer for the simplest point-to-point application to the most complex Master-Remote SCADA systems, let Data-Linc Group be your one stop source for reliable data communication equipment.
