Device Addressing
Each UCM must have a unique address on each link. Voyagers can have
an address from 50 through 81. The Voyager address is set using DIP
switches on the TCI-3 board and must match the address set in Site Con-
figuration for Tracer Summit. Refer to the TCI-3 literature for more
details about setting the address.
• For the DIP switch locations on the TCI-3 board, see Figure 63 on
page 137.
• For Voyager address DIP switch settings, refer to Table 27.
