MAINTAINING THE BRAIN
Loading New Firmware
B3000-B and B3000-B-OMUX brains contain firmware (sometimes referred to as the
kernel
), which is similar to
an operating system. If the firmware should become damaged, or if a new version of the firmware is released,
you can load new firmware to the brain using the software utility PAC Manager. PAC Manager is available as a
free download from our website,
.
Follow these steps to replace the firmware.
1.
Make sure you have the following before beginning:
–
Internet access to obtain new firmware from our website.
–
PAC Manager (from our website) installed on your PC. If the brain is attached to a SNAP PAC S-series
controller, the PC must be on the same Ethernet network as the controller. If not, you need a
PCI-AC48 adapter card and an RS-232 to RS-485 adapter cable to connect directly from the PC to the
brain.
–
Part number of the brain (B3000-B for
mistic
or B3000-B-OMUX for Optomux), to make sure you
download the correct firmware.
–
Address information for the controller(s) and/or brain(s) that will receive the new firmware.
2.
Make sure the brain is in Binary CRC16 mode.
