With the base reference map, the Relay Word bits mapped into Objects 1 and
2 are shown in Table 6.11. For non-SER points in the range 0–799, use the
Index Range column directly. For SER points in the range 800–1599, add 800
to the indices in Table 6.11. The table lists eight bits in each row and the index
