Appendix I: Setting BACnet Communication Protocol MS/TP MAC
Address of Unit
The address assignment is determined by adding the values for each of the
switches that are in the ON position. The transmitter comes from the factory with all
of the dip switches, except position 1, in the ON position as shown in Figure 6
below. The address of the transmitter would be 127 as it would be
64+32+16+8+4+2+1 = 127. Another example would be if the address desired was
008, the only dip switch position in the ON position would be position 5 as shown
in Figure 7 below.

Though the minimum possible address would be address 0
when all the dip switch positions were set to OFF, and the
maximum possible address would be address 255 when all of the dip switches were
set to ON, the transmitter only has valid address from 1 to 127. Any address outside
of this range will give an error code.
