Updating the Firmware
Extron periodically updates product firmware in conjunction
with the release of new software revisions. When updating any
Extron software to the latest revision level, be sure to read the
supplied release notes or contact an Extron Application Engineer
to determine if your Extron product requires a firmware update.
You can find out what version of firmware is currently loaded
on your switcher by entering the SIS “Q” command via the
RS-232 interface (see “Using Simple Instruction Set (SIS)
Commands,” earlier in this chapter).
