Industrial Transparent Data Modem

اطلاعات محصول

The TM-100 modem is a telecommunication modem with 2G/4G connectivity and equipped with an RS485 electrical port, and it structurally supports the DLMS protocol. Since, in the DLMS protocol over the RS485 port, data exchange is performed using the Direct HDLC format, while at the application layer the transmitted format must be DLMS Wrapper, the modem acts as a protocol conversion unit, converting Wrapper format to Direct HDLC and vice versa. The operating process of the modem is as follows: commands sent from the central management software are received by the modem, converted into Direct HDLC format, and then transmitted to the connected device. Subsequently, the data received from the connected device is converted into Wrapper format and sent back to the software. All communication interactions between the modem and the central management software-including sending and receiving commands and data, as well as modem and telecommunication infrastructure configurations-are carried out in accordance with the DLMS/COSEM standard. The TM-100 modem supports both local and remote configuration, providing flexible deployment and management options for smart metering and telemetry applications.
