SRM6220-Hybrid Ethernet-Serial Modem—
900MHz ISM Band

Data-Linc Group’s SRM6220 wireless Ethernet-serial modem provides users an advanced, state-of-the-art blending of Data-Linc’s successful SRM6000 serial and SRM6210E Ethernet modems. The SRM6220 offers Ethernet to serial, and EtherNet/IP to DF1 connectivity for hybrid integration of serial and Ethernet devices. Only the modem is required for this integration which reduces cost and increases efficiency. The accompanying SetLinc^TM software makes SRM6220 configuration easy and intuitive.

SRM6220 meets or exceeds the prior technology. Its updated features and cutting-edge auxiliary microprocessor add a broad range of enhanced, user-friendly features and capabilities. The SRM6220’s backward compatibility with the SRM6200E and SRM6210E Ethernet modems allows it to be used as a replacement. It can be used as a serial tunnel Master with SRM6000 modems with series 2.xx radio firmware.

Modem setup and configuration have been simplified by Data-Linc’s proprietary SetLinc software. Configuration via the Ethernet or the serial port (RS232) provides versatility. To further simplify installation and increase user confidence, the SRM6220 is “ping-able.” Radio network communication can be readily determined by pinging the Master or the Remote— an invaluable troubleshooting feature for determining if the communication link is functioning.

Additional advantages of the SRM6220 include Ethernet bridging, selectable MAC (Media Access Control) address filtering and dual Ethernet/CAT5 connectors for straight or crossover cables. The radio network forms an Ethernet bridge between Master radio Ethernet devices and one or more Remote radio Ethernet devices. RF network performance is improved by a switchable MAC Filter in each radio that learns MAC addresses of Ethernet devices connected to its wired side and only forwards packets across the RF link of devices not on the wired side.

Like the prior SRM Family 900 MHz modems, the 25+ miles (40 km)* range offers superior reliability and performance in the license-free band. The SRM6220 utilizes the same high performance, ultra-reliable Smart Spectrum^TM technology that ensures exceptional data integrity— even in high noise environments. It continues the SRM Family tradition of allowing each modem to be configured for Master, Remote, Repeater or Repeater/Remote mode. The SRM6220’s compact design with optional DIN rail clip, allows easy mounting. The front panel power and data connectors give the user immediate connectivity and front-located LED status lights provide direct visual access to critical diagnostic information.

*Greater range in optimal conditions with clear line-of-sight, Repeaters and/or higher gain antennas.
