Keysight PXI/AXIe Chassis Troubleshooting Guide 13
Understand the Software Components
Chassis Software Driver
The chassis software driver is the component that lets the host controller
operating system communicate and control the chassis. The driver, specific to
the chassis you are controlling, needs to be installed in the host controller to
communicate with the chassis. If the chassis driver is missing or not updated to
be compatible with the firmware, communication issues may result. Drivers are
often supplied with each chassis on a CD. The latest drivers are always available
on the product’s Keysight web page. Keysight recommends that you always use
the latest, most up-to-date drivers.
Module Firmware
Like the chassis, the module firmware is part of the module and controls the
module’s lower-level hardware components. Every module comes from the
factory with firmware installed on it. If a module’s firmware is missing or out of
date, communication issues may result. The latest firmware (if any) and
installation instructions are always available on the product’s Keysight web page.
Keysight recommends that you always use the latest, most up-to-date firmware.
Module Software Drivers
Every PXI or AXIe instrument module, including Embedded Controllers such as
the M9037A or M9537A, also needs to have its driver software installed on the
host controller. If any module’s software drivers are missing or out of date,
communication issues may result. A missing system module driver can cause
inconsistent and/or incomplete chassis enumeration. Drivers are often supplied
with each module on a CD. The latest drivers are always available on the
product’s Keysight web page. Keysight recommends that you always use the
latest, most up-to-date drivers.
