Note: Because CM-5RB modules install vertically in 3RU shelves, “UP” and “DOWN” on the toggle
switches actually refer to right and left respectively in an ACS-163, ACS-165, ACS-166, STL-

1.5.1 Function Groups and Configuration Switches
The user-accessible CM-5RB functions are organized into groups and include
● Setup options such as SF and ESF (frame formats).
● Current status conditions such as receiving all ones.
● Informational items such as the CM-5RB firmware revision.
The groups are accessed from two different configuration group menus.
● Basic configuration: This group menu provides the settings used in most configuration setups.
Section 3.2 – CM-5RB Basic Configuration Group Menu gives a detailed explanation of the menu
settings.
● Advanced configuration: This group menu provides settings for CM-5R-TD functions and other
specialized applications that rarely need adjustment in most systems. Section 3.3 – CM-5RB
Advanced Configuration Group Menu gives a detailed explanation of the menu settings.
