Module Configuration Using the Backplane
The interface module can be configured through backplane
communications using any SLC fixed, 5/01, 5/02, 5/03, 5/04, or 5/05
processor. This chapter guides you through the configuration of your
interface module using backplane communications.
Once you complete the configuration, return to page 4-15 for
instructions on completing the installation of your module.
Topics for this chapter include:
• configuring the interface module from the SLC processor.
• placing the module into software Run mode from the SLC
processor.
• reading the module’s configuration from the SLC processor.
• examining the SLC processor’s status word.
• building the DF1, DH-485, and Modem Init String configuration
packets.
• using the Real Time Clock.
• establishing a Data Echo between the interface module and the
SLC processor.
• resetting the interface module from the SLC processor.
Overview In this method of configuration, the SLC processor uses the backplane
to load the configuration data into the Output Image file for the
interface module. By assigning a Data ID value in the Output Image
file you designate which parameters to configure.
IMPORTANT
Configuration through the backplane is an alternate
configuration method than that presented in Chapter
5. If you prefer to configure your module using an
ASCII terminal, or have already done so, you do not
need to go through this chapter. Instead, return to
Chapter 5 for directions on configuration with a
terminal or move on to Chapter 7.
