Synergis™ IX

For optimal performance, ensure that your Synergis™ IX controllers and reader expanders are running the recommended firmware.

What you should know

About upgrading controllers:
  • Synergis™ IX controllers can also be upgraded through the Synergis™ IX Portal, or through the Synergis™ Appliance Portal like other interface modules.
  • For more information, see Upgrading interface module firmware through the Synergis™ Appliance Portal.
  • For security reasons, starting in Synergis™ IX controller firmware 4.00_965_M0A1, firmware downgrades are no longer possible.
About upgrading reader expanders:
  • Synergis™ IX reader expanders must be upgraded through the Synergis™ IX Portal.
  • To prevent upgrade failure, you must physically disconnect all readers from the RS-485 ports of the reader expanders before upgrading.
IMPORTANT: Updating reader expander firmware puts the controller into maintenance mode, preventing normal activity for the duration of the update process. The firmware must not be updated remotely.
