Assigning modules to slots
To monitor a module installed in a specific slot, the management system must
have previously assigned that module to the slot. If the module was not
assigned, the CHANNEL display will indicate
00
and remain in this state, even
if you attempt to change the selection.
If a module in a slot is replaced with a module of the same type, the display
will not change and the system will read the monitoring result for the channel
that was last selected. If a module has to be replaced with a module of a
different type, the new module must be assigned to the slot. Then, a new
MODULE and CHANNEL selection must be made.
Monitoring options
The system can monitor a number of channels in different modules
simultaneously. This feature is useful when traffic passing through different
modules in the XDM-300 has to be analyzed.
After monitoring channels of different modules, all selected channel numbers
of these modules are saved in the ECU-F's memory.
You can connect test equipment to various modules or connect test equipment
with multiple inputs to simultaneously monitor the traffic passing through the
channels in these modules.
Monitoring Signal Levels
The following table lists the normal signal levels at the monitoring points for
the various modules.
