PC Access Version 3.15.0.799 (15/October/2015)
- Added OmniTouch 7 Kernel Version 1.1 and OmniTouch 7 Firmware Version 1.12 to the update site. See Technical Bulletin TB-18 for instructions on installing these updates.
This upgrade improves connection reliability, video connections and eliminates a soft sound that can be heard when you hold your ear up to the speaker. Furthermore, this upgrade will eliminate the possibility of the touchscreen producing a static noise from the speaker that can be heard from a distance. Note that although the static noise is annoying if it happens, it does not pose safety or functionality issues.
Note: These updates must be applied together in order.
The OmniTouch firmware upgrade file (e.g. OmniTouch_7_Version_1.12_99A00-1_2.ot7f) must be applied first.
Wait for the touchscreen to reboot, then the Kernel upgrade file (OmniTouch_7_Kernel_Ver_1_1_99A00-1_2.ot7f) must be applied.
After the OmniTouch 7 restarts, press the Settings icon on the bottom-right of the OmniTouch 7 menu bar.
Press and hold the Settings icon for 3 seconds.
The firmware version is displayed in the title bar. Verify that the Kernel Version is 1.1 or higher.
- Fixed a few typos and text display issues.
--------------------------------------------------------------------------------
PC Access Version 3.15.0.790 (03/June/2015)
- Added the ability to filter the firmware download list. PC Access 3 supports several models of controller in several languages. This makes the list of available firmware files rather long. Often you may be only interested in a particular language, or model. The filter looks for text matches in the file names so typing "english" in the filter box will only display English controllers. Typing "IIe" will display only Omni IIe controllers, etc.
- Added support for Leviton and Logenex TELEPORT door stations.
--------------------------------------------------------------------------------
PC Access Version 3.15.0.789 (14/May/2015)
- Fixed problem where the download firmware files window was not big enough to display all of the available firmware files.

--------------------------------------------------------------------------------

My personal OmniPro 2 issues over the last few years...
1 - Network / serial bus would get constipated. The laxative I chose was to install a micro router between the OP2 NIC and the main network. There are notes in the release notes relating to network but nothing specific.
2 - Camera displaying in the Omnitouch 5.7e screens. I made mine work. Later a firmware update fixed much of this except for keeping a 4:3 display of video rather than a wide screen display of video. Another issue was a pop up video screen on the Omnitouch 5.7 legacy screens.
So personally having two issues across many firmware updates is not too bad. I never purchased the Email board or the Android Omnitouch 7 screens here.
