As of the date of this release, all newly manufactured IPDCs will include an updated version of firmware that includes a new initialization tone when powering on the IPDC controller.
Please note: This update will not require any currently purchased or installed IPDC controllers to be replaced.
New Initialization Tone
A new initialization tone has been added that announces the I/O board’s microcontroller firmware version through a series of short beeps. This release of the I/O board firmware is version 2.3; the sounder will beep twice, pause, and then beep three more times.
