What Is Cut-Through Switching?

The channel switching device (hereinafter referred to as SMC) is a product that solves the mutual conversion of multiple serial communication methods and the multiple switching methods between dual channels in response to the actual application needs of signal acquisition sites in communication networks such as power and telecommunications.

Features

Has multiple configurable dual-channel switching methods

SMC adopts single-chip microcomputer control, and has multiple configurable dual-channel switching methods, as well as serial conversion between input channels and output channels. Its fast switching speed, small disturbance, high transmission efficiency, adjustable delay time, and no loss of data transmission provide users with a completely "transparent" full-duplex channel.

The SMC has the function of converting RS232 / 485/422 serial characteristics between the input port and the output port. It combines the "through", "crossover", "one-to-two", and " "Automatic judgment" and other channel switching methods can be flexibly applied to the data collection and forwarding site of each automation system. For example, when the redundancy of the main and standby channels is required, or when there is only one channel of data in the equipment channel, and the acquisition system requires two equal channels of data, or when there are many equipment channels, but the serial interface methods are different ... Combine its functions to complete the user's requirements. And because of the signal gain function between its input port and input port, it can also act as a signal gain extender in a long-distance transmission channel as required.
