This download contains current firmware for the SNAP-PAC-EB1 and SNAP-PAC-EB1-FM brains. Current firmware for all SNAP PAC brains and controllers is available in a single download here.

See the SNAP PAC Controllers and Brains Firmware Release Notes (also called README) document for information on the changes and fixes in the current version of this product's firmware.


To install firmware, use the most recent release of PAC Manager (you can download the latest version from the Opto 22 website). Older versions of PAC Manager cannot install certain levels of firmware on controllers and brains shipped after certain dates or with certain versions of firmware currently installed on them.

Some EB and SB brains shipped after April 2, 2018 shipped with new flash components, PAC firmware R9.5g (or higher), and new bootloader firmware. Lower versions of firmware are not compatible with these controllers. For instructions on recovering controllers that are accidentally installed with lower versions of firmware, review the SNAP PAC Controllers and Brains Firmware Release Notes document.
