Purpose:

DCT-1200w is a portable data conversion product that can amplify signals from communication links and, in conjunction with a handheld device, access downstream meter units through addressing to achieve centralized meter reading and standalone meter reading functions. The device adopts wireless remote transmission technology, which can be connected to the downstream meter at a long distance, making up for the disadvantage of handheld devices that cannot operate the meter online in some special situations. At the same time, it is compatible with the upstream RS485 interface and supports flexible docking of handheld devices with RS485 interfaces currently on the market. This product can support M-BUS or RS485 downstream data communication interfaces, and upstream data is communicated wirelessly with the handheld device.
