How many addresses are supported by the X10 protocol?

A. 128

B. 256

C. 512

D. 1024

Solution

Answer B is the correct answer. The X10 specification sets up an address structure supporting a total of 256 different addresses. Answers A, C, and D are each incorrect for the same reason—they each contain the wrong values for the total number of addresses available with the X10 protocol.
