Data-Linc Group’s new wireless, licence-free SRM6100/EU Serial Modem offers superior reliability, versatility and performance for industrial wireless serial transmission. Designed to meet European CE Mark and ETSI RF regulations, the SRM6100/EU combines advanced frequency hopping technology and a highly sensitive RF receiver to maximize transmission range and industrial performance.

The SRM6100/EU employs Smart Spectrum™ frequency hopping spread spectrum (FHSS) technology in the 2.4 - 2.4835 GHz frequency band for secure, robust communication. Data-Linc Group’s FHSS technology, coupled with 32-bit CRC error detection, enables the SRM6100/EU to reliably deliver critical information.

The SRM6100/EU has a rated range of 11.3 km (7 miles), and the built-in Repeater mode may be used to extend range or work around obstructions. For multi-point applications, one Master can communicate to an unlimited number of Remotes when a polled protocol such as DF1, Modbus or DNP is used.

The SRM6100/EU is easily field configurable and includes built-in diagnostics to evaluate RF signal quality during installation and operation. (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.) Additionally, Data-Linc can pre-configure the modems and provide correctly pinned serial cables for even easier installation.

The SRM6100/EU is designed for extreme environments. It is rated for extended temperature operation (-40° to +75° C) and may be powered from a 230 VAC adaptor or 10 to 28 VDC voltage sources.

• Cost-effective alternative to factory floor cable installation
• Communications to mobile equipment (automatic guide vehicles, conveyor systems, transfer cars, overhead cranes, warehouse automation, etc.)
• Eliminates trenching to pump stations, storage tanks, pipelines, sub-stations and control rooms for SCADA communications
• Communications over bodies of water, highways and other obstacles
