Main -> Local -> Data -> Input Mapping:
This screen allows you to assign a data input channel to a data output channel over
a selected fiber port. The number under the middle oscilloscope icon indicates the
currently selected input channel. The numbers under the oscilloscope icons to the left
and/or right of the middle oscilloscope icon represent the output channel numbers. The
arrows to the left and/or right of the middle icon (labeled A and B, respectively indicate
over which fibers this mapping is enabled. If the selected input channel is mapped to the
output channel then a square-wave is displayed on the oscilloscope icon and the arrow
is displayed. If a mapping does not exist for the selected input and output channel pair,
then the square-wave and the arrow are not displayed. The status of the input data
signal is depicted on the screen of the middle icon:
• Z: A high-impedance condition is detected at the data input
(i.e. no equipment is driving an active signal).
• H: A high level is detected at the data input (i.e. a logic-1).
• L: A low level is detected at the data input (i.e. a logic-0).
