SRM6030 Wireless Serial Radio Modem
902-928 MHz

Data-Linc Group's SRM6030 license-free wireless serial modem for the 900 MHz ISM band

Features License-free wireless— operates in the 902-928 MHz ISM (industrial/scientific/medical) band Din mount optional RS232/RS485 data port Range of up to 25 miles (40 km) and in- stalled range of up to 35 miles (56 km) with line-of-sight and an omni directional an- tenna—farther with Repeaters or higher gain antennas Full DB9 connector for disagnostics and data LincViewTM RF network diagnostic software included Up to 256 bit AES Encryption Employs Smart SpectrumTM frequency hop- ping technolaogy for maximum data integrity — even in high noise environments Factory or field configured for your applica- tion, ensuring trouble-free installation Operates as Master, Remote, Repeater or Repeater/Remote mode User adjustable hop patterns and frequency zones for refined operation of close proximity networks.

Data-Linc Group’s wireless, license-free SRM6030 Serial Modem offers superior reliability, versatility and performance for wireless serial transmission. It offers an unsurpassed rated range of up to 25 miles (40 km) and an installed range of up to 35 miles (56 km) with line-of-sight and omni directional antennas, farther with Repeaters and/ or higher gain antennas. The SRM6030 is the next generation of the proven SRM6000 serial modem, and is fully backward compatible.

The SRM6030 employs Smart Spectrum^TM frequency hopping spread spectrum (FHSS) technology in the 902-928 MHz frequency band for secure, robust communication. Data-Linc Group’s FHSS technology, coupled with 32-bit CRC error detection and AES encryption enables the SRM6030 to reliably and securely deliver critical information.

RF site surveys are usually unnecessary and an FCC site license is not required. The SRM6030 wireless technology eliminates the need for hard wire or fiber cable, which are often expensive and difficult to install.

The SRM6030 supports a number of configurations, including point-to-point and point- to-multipoint as well as multiple Repeaters if required. Multipoint operation permits an unlimited number of Remotes. The SRM6030 can also function as a Repeater/Remote to extend range or work around obstructions. Back-to-back radio modems are not required for Repeater function.

Industrial Applications

The SRM6030 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 SRM6030 utilizes Smart Spectrum technology— ideal for critical applications that demand reliable and secure communications. See also Smart Spectrum FAQ.
