On all ICT products, there is a label clearly marked with the product name, interface, voltage and serial number. If it is necessary to understand the naming of the product, please refer to the product manual.
Take the "L" series as an example; there are three banks of DIP Switches for different purposes. One of them is below the motherboard (DIP 4), and the other two are on the side of the unit (DIP 10 and DIP 4)
For detailed specifications of the DIP Switch settings, visit our “Manual Download”.
