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).
