Keysight M9502A/M9505A AXIe Chassis User Guide 105
Chassis Backplane Connections For Module Developers
Zone 2 Connector Usage
Your module may implement any or none of the Zone 2 connectors. If you want:
- to utilize the AXIe trigger, timing, data, and local bus (22 pair) features in your
module, load connectors J20 and J23.
-
to expand the local bus up to 62 pair, load connectors J24 and J21.
-
to complete a five-slot star hub for data fabric channel 2—used in instrument
hub modules only—load connector J22.
The table below provides a locational map linking each AXIe Zone 2 interface
type (function) with its backplane connectors
For both chassis, these pairs are also provided to slot 1:
For the M9505A chassis only, backplane connector P22 is added to slot 1:
Complete circuit definitions and design specifications can be found in the ATCA
and AXIe specifications. Pin assignments are listed on the following page.
