Data-Linc Group’s wireless, license-free SRM6100 Serial Modem offers superior reliability, versatility and performance for wireless serial transmission. The SRM6100 is factory pre-configured for easy, hassle-free installation. It offers an unsurpassed rated range of up to 15 miles (24 km) with line-ofsight and omni directional antennas, farther with Repeaters and/or high gain antennas.

The SRM6100 employs Smart Spectrum^TM frequency hopping spread spectrum (FHSS) technology in the 2.4-2.4835 GHz frequency band for secure, robust communication. (Data-Linc Group’s LincView™ Diagnostic Software, an optional RF network diagnostics management tool for stand-alone SRM modems, offers system network monitoring and maintenance from Master locations.) Data-Linc Group’s FHSS technology, coupled with 32-bit CRC error correction, enables the SRM6100 to deliver critical information.

License-free and wireless—operates in the 2.4-2.4835 GHz ISM (industrial/scientific/medical) band RF site surveys are usually unnecessary and an FCC site license is not required. The SRM6100 wireless technology eliminates the need for hard wire or fiber cable, which is often expensive and difficult to install.

The SRM6100 supports a number of configurations, including point-to-point , point-to-multipoint as well as multiple Repeaters if required. Multipoint operation permits an unlimited number of Remotes. The SRM6100 can also function as a Repeater/Remote to extend range or communicate around obstructions. Back-to-back radio modems are not required for Repeater function.

Industrial Applications

The SRM6100 Radio Modem is ideal for industrial automation systems with:

• PLCs located on moving platforms, overhead cranes and turntables or other revolving equipment
• Remote PLC programming
• SCADA systems, such as water/wastewater, utilities and oil/gas systems
• Underground or off-shore communications
• High RFI environments (e.g., steel, manufacturing)
• Industrial automation machine control on plant floors

Data-Linc Group's SRM6100 utilizes Smart Spectrum technology— ideal for critical applications that demand reliable and secure communications. See also Smart Spectrum FAQ.

LincView^TM Diagnostic Software

Data-Linc Group’s LincView^TM Diagnostic Software provides an optional RF network diagnostics management tool for any of the wireless stand-alone modems in the SRM Family. LincView offers complete system network monitoring and maintenance from your Master location. Key parameters at a remote location can be monitored or changed with a few simple keystrokes. This allows technicians to track the actual data path to the Master, view every SRM network link in miles or kilometers and monitor key parameters such as signal or noise level, voltage and much more. LincView even provides visual trend analysis of packet errors, supply voltage levels and radio temperature.
