3.7 Installing the USB Port Driver
The USB port is only used for firmware updates. USB driver files are provided as part of upgrade packages
compatible with the PNS.
With the provided installation files accessible on either a local or network drive, connect the computer’s
USB port to the USB port on the PNS module to be upgraded. When requested, direct the installation to
the proper location of the installation files.
The serial port name is COM followed by the next available number from 1 to 256. After the computer
assigns the USB port a COM port number, that computer uses the same COM port number each time it
connects to that PNS module.
Note: When connecting the USB cable to the PNS, you may receive a warning for installing a driver that
has not passed Windows Logo testing. This warning should be ignored. Because each PNS has a
different serial number, the operating system recognizes each driver installation as different.
3.8 Firmware Updates
Note: The RX3i PNS does not prevent initiation of firmware update when it is actively connected to an
I/O Controller. When the PNS enters firmware update mode, the PNS and its modules go to their
I/O default modes. During the update, the PNS does not drive module outputs or send inputs to
the I/O Controller. When the firmware update is completed and the PNS is rebooted, its previous
connections are re-established and control resumes. Refer to section 2.1.8.6 Power-up LED
Patterns.
The PNS enters firmware update mode when commanded to do so from the WinLoader update utility, or
if a firmware component is corrupted or invalid. In firmware update mode, the PNS module blinks its LEDs
in a special pattern as described previously, and its Ethernet ports are not operational.
If the PNS has experienced a fatal error, the module goes to an LED blink-code error condition and does
not communicate with WinLoader, causing WinLoader to return a timeout failure indication. The module
must be power-cycled before reattempting the update.
