SNAP-PAC-EB2 Brain Firmware

Filename: snap-pac-eb2-R9.5g.bin
File Size: 981 KB
Version: R9.5g
Last Update: 4/13/2018


This download contains current firmware for the SNAP-PAC-EB2 and SNAP-PAC-EB2-FM brains. Current firmware for all SNAP PAC brains and controllers is available in a single download here.


Effective April 2, 2018, some SNAP PAC controllers and brains have new flash components. These units ship with firmware R9.5g (or higher) and new bootloader firmware.

PAC firmware versions R9.5f and lower are not compatible with the new component. If you inadvertently install firmware R9.5f or lower on one of these units, you can recover by using the Failsafe Bootloader Mode to install firmware R9.5g or higher.

For more information about the new flash component, see KB87213.

For details on Failsafe Bootloader Mode, see "Replacing Damaged Firmware" in the PAC Manager User's Guide, form 1704. NOTE: Opto 22 recommends that you always use the most recent release of PAC Manager.

See the README document for information on changes and fixes in the current version of this product's firmware.
