Output Module Reference Data
DS1 Output Module
A microcontroller unit on the DS1 Output module communicates with other boards
in the main shelf and performs Output module configuration. The module’s memory
subsystem (EEPROM, RAM and serial EEPROM) stores the executable image, the
PLD image and other configuration and temporary information for an on-module
microprocessor.
The DS1 Output modules may be used individually or configured for operation as
redundant pairs in the shelf.
Status LED Indicators
The DS1 Output module status LED indicators are shown in Figure 8-4 and are
described in Table 8-3.
