Configuration
Configuration
The configuration of the 8900FSS establishes the operation parameters
shown in
Table 2 . The submodule configuration can be changed from
factory defaults using the configuration switches on the host module.
These switches are:
■ Function Switch – a function selection rotary switch (submodule func-
tions are usually addressed by the second bank of selections on this
switch).
■ Toggle Switch – a momentary toggle switch that actuates the selection
when switched either up or down.
Refer to the instruction manual for the host module for configuration
instructions.
Remote Configuration and Monitoring
The 8900FSS is designed to operate in 8900TX, TF or TFN frame versions
that support GUI-based configuration and monitoring. A PROM upgrade
on the host module may be required to activate frame bus communication
if the module is moved from a non-networking frame to a networking
frame.
