A Note Concerning Level Numbering and External Control Computers Using ASCII Protocol

ASCII protocol switching instructions include specification of output, input, and level; with level indicated by a number from

1 to 7. These level numbers correspond to the order in which levels are listed on the CP Level Set table. In the example table

shown in Figure 5−46, the ASCII level numbers would apply to the switcher levels as follows:

Do not confuse these ASCII level numbers with the logical and physical level numbers of the switcher, which may be differ-

ent. (The level names on this table are translated to logical and physical level numbers on the Switcher Description table, as

shown on page 5−35.)
