The me-D150 range is the latest addition to our family of highly versatile modems. A powerful 5W UHF and VHF modem that provides low cost world wide solutions.
The me-D150 offers great flexibility and is designed to be small and robust. The modems are fully environmentally tested to resist water and dust ingress, power is by 9-18 dc volt supply with low current consumption mean saving on maintenance and power drain.
The me-D150 is suited to simple low cost applications. It offers a 0.5 - 5 Watt RF modem with Direct FM / FSK as standard and a useful Bell202/V23 option ensuring backward compatibility with certain legacy systems.
The me-D150 is ideal for applications requiring a flexible, cost effective point to point communication such as simple telemetry, tele-command and tele-control to / from outstations or machinery, alarm signaling and database interrogation.The unit can also be used in SCADA applications.
The me- D150 has been designed with International standards in mind and will help your voice and data communications solution become a global reality.
