ADCP-50-304 • Issue 19 • June 1999 • Section 7: Operation

flag ($) occurs in the AB command string, the user must issue a GO command to perform the switching operations. If an execute flag (#) occurs in the AB command string, the CM executes the AB command string immediately when it is received.

Caution: When using Autofallback, the operator’s switching commands may be negated. That is, modules in alarm state switch to the side specified by the jumper (A or B). This switching operation is performed regardless of the operator’s commands.

The The format for the AB command is:

AB , <namslot> , <numslot> , <numskip>, <action> ,<flag>

Table 7-8describes the syntax for the command string parameters and defines the operations performed when the AB command executes.
