RVON-16, version 2.4.4
----------------------

Included Files:
---------------

Release Notes:    readme.txt
Main application: rvon16.bib
Boot code:        adam2EB.bin
Utilities:	  abortos, applodr, aupdater, cmp, cp, defrag, ftp, info, 
                  printenv, rm, setenv, unsetenv


Upgrade Procedure
-----------------

Normally, a new version of the main application (rvon16.bib) would be installed 
simply by  downloading it from RVONedit or AZedit.  However, it may
occassionally be necessary to replace the boot code (adam2EB.bin) and/or the
onboard utilities, which requires the use of the RVONFILE utility.


New in version 2.4.4
--------------------

Fixed security issue with authentication of telnet users.

In some rare circumstances, it is possible for the RVON-8/16 cards to stop 
receiving control bus messages from the master controller.  This version
of firmware can detect if this occurs and recover from it without having
the card reset.


New in version 2.4.2
--------------------

Improved keypanel communications.

Fixed SNMP channel reporting bug.

Fixed a backward compatibility issue with RVON-KP/IO V2.3.x

This version is now backwards compatible for audio and trunking with previous
versions of RVON firmware.  However support for 255 intercoms and new KP protocol
for keypanels connected via RVON requires V2.4.2 or later in the RVON-KP/IO.


New in version 2.4.0
--------------------

Support for trunking of up to 255 intercoms. 
(Requires a TM-10K Trunk Master, plus intercom and keypanel firmware support).

Support for new keypanel protocol (which can cut firmware download times in half).  
(Also requires intercom and keypanel firmware support).

Fix for control bus issue. It was possible in certain instances for the RVON to 
stop receiving control bus messages and then reset.  Fixed.


New in version 2.3.1
--------------------

This version fixes a bug in support for up to 128 keys where if an
RVON keypanel powers up shortly after the MCII-e has been reset, the MCII-e
may not recognize that the keyanel supports up to 128 keys.


New in version 2.3.0
--------------------

Support for keypanels with up to 128 keys

This version is backwards compatible for audio and trunking with previous
versions of RVON firmware.  Support for RVON keypanels requires V2.3.0 or 
later in the RVON-KP/IO.


New in version 2.2.0
--------------------

Support for the separate CWW key on the KP 32 CLD (65th key)

Support for the Port Allocation Table (reallocation of ports/timeslots)

Support for Micron flash type (replacement for Intel part)

Requires new adam2EB.bin boot code and utilities to support Micron flash type

Periodically report card type to intercom 

Forward GPIO output states to RVON-IO (even if no keypanel present)

Ask MC for desired alpha sizes when MC asks what sizes we need

Ask MC for desired alpha sizes when MC sends alpha universe size

VOX key state may not have been handled properly (Fixed)

Multiple crosspoint message from MC may not have been handled properly (Fixed)

Better handling of loss of control bus clock

This version is backwards compatible for audio and trunking with previous
versions of RVON firmware. Support for RVON keypanels requires V2.2.0 or 
later in the RVON-KP/IO.


New in version 2.1.6
--------------------

This version includes a new FPGA image that improves control bus handling.

This version includes support for the RVON-2, and updated telnet command help.

This version includes an updated ASIC driver (improvements ported from the AIO-16).


New in version 2.1.5
--------------------

This version ignores blank Ethernet link configuration from the intercom.  
This fixes a potential problem where: if an RVON-8 card at V2.1.0 or earlier is 
replaced by an RVON-16 after the intercom has already been upgraded to V1.19.x 
(DBX) or V1.6.x (MCII-e), then the card will lose its Ethernet link  
configuration settings and be forced into 10Mbps, half duplex. If the switch to 
which the card is connected is fixed at 100Mbps, full duplex, then the card 
would not be able to create an Ethernet link.


New in version 2.1.4
--------------------

Make sure there is enough free flash space to download new code image.

Improvements to control bus handling.
 

New in version 2.1.3
--------------------

DIP switches for RS232/485 selction on serial port 1 and 2 were incorrect.


New in version 2.1.2
--------------------

Initial release.
