Updating the Firmware
Extron periodically updates product rmware in conjunction
with the release of new software revisions. When updating any
Extron software to the latest revision level, be sure to read the

You can nd out what version of rmware 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).
