IFBR1a Firmware Revision History

This model is not capable of firmware updates in the field so no files are available for download. Contact Lectrosonics if you need a firmware update.

 

IFBR1a v4.1 - 22 February 2017

Fix bug where, if more than one frequency is stored in memories, the first button press after a power cycle visits the second channel (with the correct indication of 2 LED blinks), rather than the first channel.

IFBR1a v4.0 - 29 September 2016

Added an alternate ("direct entry") user interface mode, accessible via a special hex switch and power switch combination, which provides extended features. By default, the original user interface mode is selected, so that the only visible difference (from v2.4) is rapid burst of LED blinks at power-on, indicating an updated unit with extended features available.

This version is compatible with any IFBR1A, IFBR5A or IFBR1A/E01 receiver currently running firmware 2.0 or newer. [The same program can be used on export and non-export units.]

IFBR1a v3.0 - 26 November 2013

The new 17422 audio boards are incompatible with firmware versions 2.x and older. Use version 3.0 (or newer as available) with these boards, but continue to use version 2.x on the older 17300 audio boards.

IFBR1a v2.4 - 19 June 2009
