UPDATING THE G4LC32ISA-LT FIRMWARE
The G4LC32ISA-LT uses a real-time, event-driven operating system, or “kernel”. The processor’s
kernel executes the strategy created in OptoControl. The G4LC32ISA-LT comes loaded with the most
current Opto 22 kernel. The G4LC32ISA-LT also comes with a disk containing the current kernel as
well as the OptoTerm Utility program for updating the stored kernel. The latest kernels are also
available on Opto 22’s Bulletin Board System.
Note to Cyrano users
: Cyrano is not compatible with the factory-loaded OptoKernel. The flash
firmware utility disk included with the G4LC32ISA-LT contains the current Cyrano kernel as well as
the Flash 200 Utility Program for downloading the firmware. OptoTerm may also be used to download
a Cyrano kernel.
Each processor has a boot loader permanently stored into a non-erasable portion of its flash memory.
This boot loader enables a user to download a new kernel as Opto 22 makes new kernels available,
even if the existing kernel has been lost.
To update a kernel, use the OptoTerm utility included with FactoryFloor. For details on using the
OptoTerm utility, consult OptoTerm’s on-line help, or the
OptoControl User’s Guide.
The boot loader currently supports only the ISA bus and COM0 as primary host ports for kernel
updating.
