Even today, harmonic telegraphy, which this new KEYMILE modem supports, remains ideal for certain applications. These include serial data transmission along railway lines or use for narrowband applications in power utility networks. In these environments, products must last for decades and have reliable and consistent manufacturer support. While other vendors have long since abandoned this market, KEYMILE offers harmonic telegraphy modems with state-of-the-art technology and continues to meet the ongoing demand for these products.
The HY101-WT2400 is a compact and attractively priced harmonic telegraphy modem that network operators can mount on a DIN rail. It is a multi-purpose FSK modem compliant with ITU (International Telecommunication Union) standards and can therefore be connected to other data transmission devices. The system is designed to transmit data over 2 or 4 copper wires at modulation rates of 50 to 2500 baud. Distances of up to 30 kilometers can be covered using unloaded 0.8 mm diameter telecommunications cables. A V.24/V.28 (RS-232) interface provides the connection to the data terminal equipment.
Digital processing of analog signals enables accurate reproduction of transmission behavior, is less sensitive to ambient influences, and offers long-term frequency stability. Comparison with analog switches is no longer necessary. Customers will be able to use VFT modems for years to come without encountering the usual problems of specialized component discontinuation.
There is still strong demand for harmonic telegraphy. While more and more manufacturers are withdrawing from this market segment and obsolete products, KEYMILE can still offer innovative solutions thanks to its flexible, software-based technology. The new HY101-WT2400 underscores this long-term market focus.
The new HY101-WT2400 modem will be available starting in April.
