Product Description

The GDSCM0 is a SCADA radio modem for master station with RS232 serial interface port. It is ideal for both point-to-multipoint and point-to-point applications, including remote meter reading (gas, electricity, heat), remote control of water distribution, remote control of irrigation systems and environmental monitoring.

Radio Modem For Master Station

In licensed systems, the master station may be assigned the primary transmit frequency that is used to communicate to all remote radios in the network. GDSCM0 radio modem supports half-duplex operation and enables transmission and reception working on the same frequency or different frequencies.
