Input/Output Modules
To extend the capability of the Electra 9200, there are 5 slots for optional input/output
modules in the rear of the chassis. These provide additional audio encoding capabilities,
audio & video decoding, or transport stream input/output options. Refer to Optional Features for
additional information on each of these modules.
NOTE: Before making changes to the FLEX-1 Module, make sure the service configuration is cleared
before powering down the system.
