remote enable button/switch (or its substitute*), turning on the system power.
After two or three seconds, release the switch. The new firmware will be
transferred to the selected module. The procedure will take up to two
minutes. When finished, the module will assume its initial state. (If you have
a 292e, you may see indication of any programming within the system on it’
blue LED.) Wait up to two minutes or until the module’s lights return to their
normal state.
See *Exceptions to the remote enable are mostly for
modules with 2 processors and
therefore 2 programming procedures.
The same switch that when held displays the
module’s firmware and module ID also substitutes for the remote enable switch in Firmware
updating procedures. One exception: The 225h does not report it’s firmware version but
firmware can loaded by connecting the input of the gate-to-pulse converter on the upper left
of the module to a voltage >2.5v (e.g., the output of the Euro-to-Buchla CV processor on
the 225h with the pot offset set to 5v and banana cable from the blue “out” jack to the white
banana jack).
