The DCM300 is designed for critical telemetry and remote control data communication over high-availability TETRA networks, but for added security, it offers a backup GPRS modem option.
The module incorporates all the routing logic for these protocols and features a web interface that allows for complete device configuration and operation. Its high flexibility and programmability enable it to be adapted to the specific characteristics of any project.
Two key features provide unique functionalities for communication in critical environments: it optimizes and expands communication capacity within the TETRA infrastructure and includes an auto-power-off function to enter a programmed sleep mode for ultra-low-power applications.
TETRA Network Resource Optimization.
In TETRA private radio communication networks, data communication systems for telemetry applications typically coexist with the voice traffic carried by users, which is undoubtedly a priority and whose integrity must be preserved. To maximize the use of limited network resources while maintaining quality of service, THAUMAT has implemented an optimization mechanism in its DCM300 equipment. This mechanism is based on the use of the various data communication services that TETRA offers: Packet Data and/or SDS instant messaging for TCP/IP routing, as well as associated industrial protocols (IEC 104, Modbus TCP, etc.). This mechanism automatically manages the use of both services based on the TCP/IP traffic carried by remote units, eliminating bottlenecks and dynamically adapting to the nature and needs of each element's data traffic.
Ideal for environments without mains power.
Sometimes it's necessary to provide data communications to sites that, due to their nature or location, lack mains power or have unstable or limited power sources. The DCM300 is designed for this purpose, incorporating an ultra-low-power auxiliary processor that allows the equipment to be powered off and on according to a schedule or triggered by external events such as alarms. This allows it to enter a standby state with no appreciable power consumption when it's not in use.
The operating mode can be easily programmed via a web interface, allowing you to define parameters such as the duration of these standby intervals, which ultimately determine the average power consumption and system autonomy.
The DCM family is completed with the DCM400 module, with similar functionalities to the DCM300 but with a more compact design that allows the use of external radio terminals (TETRA or others).
