ESM PCIe Upstream Connection Settings
The section for the ESM PCIe Upstream Connection displays the current PCIe
configuration (called the
Active Configuration
) and allows you to change the
configuration if necessary.
New Configuration
The New Configuration field allows you to designate a PCIe Upstream
Connection or designate an enumeration wait time. As a general rule, you should
not need to reconfigure these; you should leave the PCIe Upstream Configuration
in Auto mode.
If you do select a new PCIe Configuration and/or enumeration wait time, you
must click the
Apply New PCIe Settings
button to save the changes as the new
default. The changes take effect after cycling power on the chassis. To restore
the factory default setting, click the
Restore Factory Default
button.
PCIe Upstream Configuration:
The possible PCIe Upstream Connections are:
- Auto:
The ESM automatically determines the upstream connection port. This is
the default setting.
- PCIe Front Panel:
The PCIe upstream connection port is the ESM PCIe
connector.
- USB Front Panel:
The PCIe upstream connection port is the USB PCIe
connector. This option is available only if the Option U20 USB ESM is
installed. See
“AXIe Embedded System Module (ESM) Option U20 with USB”
- Slot 1 (Instrument Hub):
An embedded controller (such as the Keysight M9536A)
can act as a PCIe root complex when installed in slot 1 of the chassis. This is
also known as the “Instrument Hub.”
Depending on your chassis configuration (ESM, embedded controller, etc.) some
of the upstream connections may not appear in the pull-down menu.
Wait Time:
You should not need to change the enumeration wait time.
However, some AXIe instrument modules (also known as Blades) take longer to
be ready for enumeration than the PXI link ready requirement of 100ms.
Consequently, it is possible for some controllers (such as the Keysight M9536A
Embedded Controller) to enumerate the chassis before all of the individual
modules are ready and therefore not enumerate them. If you have a situation
where Keysight Connection Expert and/or the Windows Device Manager
consistently do not find specific instrument modules when the chassis powers
up, increase the wait time (valid range is 0 to 60 seconds).
You should seldom need to change the PCIe Upstream Configuration. Leave it
set to Auto for the ESM to select the appropriate configuration.
