CAV6.6 Firmware Update Procedure
Note: When a firmware update is released, it is
available online at the Document Center on
www.russound.com, in Technical Documents
under Multi-zone products. The firmware update
procedure may be modified, so always check for
the latest version.
Note: Disconnect ALL RNET links in the system
before proceeding with keypad update.
Requirements:
1. PC computer running Windows 95, 98, ME, NT,
2000, XP operating system
2. Available DB9 serial RS-232 data port
(baud rate= 38400, data bits = 8,
no parity, 1 stop bit, no flow control)
3. DB9 serial cable (male to female extension)
4. Flash Magic - Philips IC update application
(Flash Magic can be downloaded for free at:
http://www
.esacademy.com/software/flashmagic/flas
hmagic.exe)
Note: the same A/C power circuit should be
used for the system and the PC. Otherwise a
ground loop may affect proper data transfer.
Update Procedure:
Remove cover lens from CAV6.6 front panel.
Remove the “Russound” program selector switch
cover with a small flat blade screwdriver.
Connect the DB9 serial cable between the PC COM
port and one of the DB9 ports found on the front and
rear panels of the CAV6.6. Make sure the front/rear
selector switch is in the corresponding position (front
or rear).
Set the OS Program selector switch to AUX or Main to
update. The hex file will be labeled AUX or Main; set
the switch to match which file is being used.
Note: Most updates will require both processors
to be updated - the AUX should be updated first.
Press and release the Reset button next to the OS
Program selector switch, or cycle the power off and
then on for the CAV6.6.
Start the Flash Magic application. If error messages
appear, they are typically generated due to communi-
cation problems. Verify all connections,close Flash
Magic, cycle power and restart Flash Magic.
