E1 Input Module Configuration
The E1 input module maintains factory default and current user configuration
information in nonvolatile memory. This information is retrieved at power up and
modified by commands from the communication module. In the event that the
current user configuration cannot be used, the module automatically reverts to
factory defaults.
Software Options
The factory settings and ranges for all E1 Input module software parameters are listed in
Table 7-4.
