This multiplexer comes with a set of interfaces and multi - function adapter plates. It enables seamless conversions between USB, TTL, RS232, and RS485 interfaces in the system. Its standout feature is the support for one - input multiple - output mode, which greatly simplifies communication among various controllers. The multiplexer board has A and B interfaces. Signals can be converted between A and B, but within the same interface, only one sender is allowed while multiple receivers are okay. For example, it can convert a USB signal to TTL, RS232, and RS485 simultaneously. Specifications include a supply voltage of 3.3V to 5V, a power LED on the board, and a size of 52x37mm (2.05X1.45'). Documents available are the Multi USB/RS232/RS485/TTL Converter Sch, driver download, FT232R Datasheet, and a Wiki page. The shipping list contains one Multi USB/RS232/RS485/TTL Converter.
Using this converter is easy. First, connect the power supply with a voltage between 3.3V and 5V. You'll see the power LED light up, indicating it's powered on. Then, choose the appropriate input and output interfaces according to your needs. Remember, if you're using the same interface, only one device can send signals, but multiple can receive. For example, if you want to convert a USB signal to TTL, RS232, and RS485, just connect the USB device to the input and the other devices to the corresponding outputs. When it comes to maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or physical damage. If you need to update the driver, you can find the download link in the provided documents. And if you have any technical questions, refer to the Wiki page for more information.
