Unique display information
Some of the information provided by an IOP Detail Status display is unique for the type of IOP. The
definitions that follow provide information that is unique to the LLMux IOP Detail Status display.
Unique LLMux IOP Detail Status targets
The LLMux IOP Detail Status display has unique data and targets as shown in the following figure. The
REQUEST FTA TYPE target provides a means of identifying the type of FTA, a thermocouple (TC) or
Resistive Temperature Device (RTD) FTA, that is attached to each Power Adapter channel. Selecting the
target produces status displayed as FTA 1 TYPE and FTA 2 TYPE with the type of FTA attached to
each channel.
Another target is the LINE FREQUENCY target which permits selection of 50 Hz or 60 Hz operation.
The selection is identified by reverse video.
