MODULE ADDRESS
This is a 4-bit in-line DIP switch with 16 coding status, namely 16 module addresses (from 100 to 115). When it is turned to ON, the status is 1. The module address formula is Module Address=1A+2B+4C+8D+100. For example, when ABCD is 0000, the module address is 100. When ABCD is 1000, the module address is 101. When ABCD is 0100, the moduleaddress is 102. Similarly, when ABCD is 1111, the module address is 115. The corresponding module addresses of DIP switch
