The Enabler Express card contains firmware (software or code) that controls the basic polling of pumps. This code works in conjunction with the pump driver DLLs running under Windows to completely control the pumps.
There is only one series of firmware, which is usually only updated when new pump protocols are added. Enabler Express cards are loaded in the factory with the latest stable code. You may need to update the firmware if you are using a pump protocol that has only recently been added.
The firmware upgrade procedure described in this page is applicable only for Enabler Express cards. For Enabler PCI, follow this link: Enabler PCI Firmware upgrade.

Firmware Code
You can get the latest released firmware from here Express Firmware
Enabler Express card firmware comes in a file with the extension .nei, and is usually named for the version e.g. enb291b1.nei for version 2.91 build 01. Enabler Express firmware starts at v2.91. It shares the same firmware with Enabler PCI, however the name and format of the firmware file are different

ExpressUpdate.exe also creates a log file of the progress so that progress and any errors are recorded.

This is saved as C:\Enabler\ExpressFirmwareBackup[Date-XX-XX-XXXX Time-XX-XX-XX].nei. Where the X's are the current Date and Time.
