Remote Control for Daisychained Multiplexers

If you are using a computer to control two or more daisy-chained multiplexers, you need to send a re-address command to select the multiplexer to control. (Up to 16 multiplexers can be daisy-chained.) Re-address commands are not printable characters; you need an 8-bit binary address or hex value to select which daisy-chained multiplexer you control. If you lose power to one or more multiplexers, you will need to use the re-address command again to select the correct multiplexer.
