The 12 DIP switches on block S1 set the base address of the UMAC Turbo CPU/Communications Board on the PC/104 bus.
Together they form a binary number. Each switch, if in the ON (closed) position, sets its bit to 0; if in the OFF (open)
position, sets its bit to 1. The possible base addresses are all multiples of 16, so switch 1 sets a bit value of 16, switch 2 sets a
bit value of 32, and so on. According to the following table, the default settings provide a base address of 528 (210h).
Note that for proper USB/Ethernet communication the host address must be set to this default value.
