1. (AUDIO MONITOR-1)
Affects:
BKC-DIP V1.01
AVR 101, Version 2.03
AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
PT 3, Version 2.03
Description:
BKC-DIP selection of Z1 Tape Input in the current preset does not work (0,S,P1=FF,3=7;). The
unit incorrectly routes the Tape Input to both the Z1 Output AND the Tape Output (instead of the
previous current Z1 input being routed to Tape Output) causing possibility of a feedback loop.
Work around:
To properly select Z1 Tape Input via BKC-DIP use the BKC-DIP command for the IR Tape
button of (0,S,I,1=D0;) which will correctly select the Z1 Tape Input. When selecting other
inputs, always simultaneously set the Tape Monitor to Off. For Example:
(0,S,P1=FF,3=0,40=0;) Z1 Current Input Tuner, Tape Monitor Off
(0,S,P1=FF,3=1,40=0;) Z1 Current Input V1, Tape Monitor Off
(0,S,P1=FF,2=1,40=0;) Z1 Current Input V2, Tape Monitor Off
(0,S,P1=FF,3=3,40=0;) Z1 Current Input TVV3, Tape Monitor Off
(0,S,P1=FF,3=4,40=0;) Z1 Current Input DVD, Tape Monitor Off
(0,S,P1=FF,3=5,40=0;) Z1 Current Input CD, Tape Monitor Off
(0,S,P1=FF,3=6,40=0;) Z1 Current Input SAT, Tape Monitor Off
(0,S,I,1=D0;) Select Tape Monitor
Fix:
Upgrade to V2.04 or later (where Z1 Current Input no longer includes TAPE, but the Tape
Monitor parameter properly handles the Tape monitoring functionality).

2. (AUDIO MONITOR-2)
Affects:
BKC-DIP V1.01
AVR 101, Version 2.03
AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
Description:
BKC-DIP selection of Z2 V2 Input in the current preset does not work (0,S,P1=FF,3=7;). The
unit incorrectly routes V2 Input to both the Z2 Output AND Z2/V2 Output (regardless of the
V2LineSetting Tape/Line Option in the System Settings).
Work around:
To properly select Z2 V2 Input via BKC-DIP use the BKC-DIP command for the IR V2 button of
(0,S,I,2=90;) which will correctly selects the Z2 V2 Input respecting the setting of V2 Line Out.
When selecting other inputs, always simultaneously set the V2 Monitor to Off. For example:
(0,S,P2=FF,3=0,8=0;) Z2 Current Input Tuner, V2 Monitor Off
(0,S,P2=FF,3=1,8=0;) Z2 Current Input V1, V2 Monitor Off
(0,S,I,2=90;) Select V2 Monitor
(0,S,P2=FF,3=3,8=0;) Z2 Current Input TVV3, V2 Monitor Off
(0,S,P2=FF,3=4,8=0;) Z2 Current Input DVD, V2 Monitor Off
(0,S,P2=FF,3=5,8=0;) Z2 Current Input CD, V2 Monitor Off
(0,S,P2=FF,3=6,8=0;) Z2 Current Input SAT, V2 Monitor Off
(0,S,P2=FF,3=7,8=0;) Z2 Current Input Tape, V2 Monitor Off
Fix:
Upgrade to V2.04 or later (where Z2 Current Input of V2 is ignored, but the V2 Monitor
parameter properly handles the V2 monitoring functionality).

3. (AUTO PRESET NAMING-1)
Affects:
BKC-DIP V1.01
PT 3, Version 2.03
Description:
The BKC-DIP eXecutive Save Preset Command (0,X,1,zoneNumber=presetNumber;cs16) does
not respect the System Parameter setting of Preset Auto Naming. The saved preset’s title is never
Auto Named, regardless of the state of Preset Auto Naming.
Work around:
Implement a save using the equivalent IR commands:
(0, S, I, 1=2;) IR Save command
(0, S, I, 1=destination digit;) IR code for destination digit
: :
(0, S, I, 1=C;) IR Enter command
Example for Saving current preset to Preset 23:
(0, S, I, 1=2;) IR Save command
(0, S, I, 1=4C;) IR “2” command
(0, S, I, 1=CC;) IR “3” command
(0, S, I, 1=C;) IR Enter command
Fix:
NOTE: IR commands for numbers are as follows:
7C IR “0” command
8C IR “1” command
4C IR “2” command
CC IR “3” command
AC IR “4” command
6C IR “5” command
EC IR “6” command
9C IR “7” command
5C IR “8” command
DC IR “9” command
Upgrade to V2.04 or later where support for autoNamingMode was added to the Save Preset
Command.

AVR 101, Version 2.03
AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
Description:
The BKC-DIP Current Input Aliase parameter for Surround Command
(0,S,F4=surroundCommand;), where surroundCommand = 0-3 on AVR 202/Ref 20 and 0-2 on
AVR 101/Ref 10, actually sets the Aliased Surround Mode.
Work around:
Do not use Current Input Aliase to control Surround Command, but instead use specific inputs
Surround Command from the following commands:
(0,G,P1=FF,3;) gets current input
Use the appropriate input Surround Command, i.e.:
(0,S,P1=FF,9=surroundCommand;) set tuner Surround Command to surroundCommand
(0,S,P1=FF,10=surroundCommand;) set V1 Surround Command to surroundCommand
(0,S,P1=FF,17=surroundCommand;) set V2 Surround Command to surroundCommand
:
(0,S,P1=FF,3A=surroundCommand;) set TAPE Surround Command to
surroundCommand
Fix:
Upgrade to V2.04 or later.

Description:
The BKC-DIP Current Input Aliase parameters do not return information when issued a G (get)
command. Using S (set) commands are fully functional.
Work around:
Do not use Current Input Aliase identifiers, but instead use specific inputs identifiers:
(0,G,P1=FF,3;) gets current input
Use the appropriate input Surround Command, i.e.:
(0,G,P1=FF,9;) get tuner Surround Command

Using BKC-DIP/RS-232 display command in Overlay mode (i.e. M1) after a display command in
Non-Overlay (i.e. M0, "blue screen") does not display text in Overlay mode
Work around:
Send Non-overlay mode display message with shortest possible timeout (i.e. T1), then after
display refreshes, issue Overlay Mode display command.

AVR 101, Version 2.03
AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
Description:
Unit will incorrectly skip the Subwoofer channel using the BKC-DIP eXecutive Command
(0,X,5;), Noise Increment Command, via BKC-DIP if the LFE Setting is set to OFF. Conversely,
the unit will incorrectly increment to the subwoofer if the LFE Setting is NOT OFF even though
subwoofer is set to NONE in the speaker setup menu. The system software incorrectly uses LFE
Setting = OFF to determine that there is no subwoofer, when it should use Sub Setting = NONE
(subwoofer NONE).
Also, the string "Spkr St = n" (where n is some number) will be displayed when using the Noise
Increment Command (0,X,5;).
Work around:
Method 1:
If sub present
Else no sub present
Method 2:
Don't use the Noise Increment command. Instead explicitly enable/disable various
channels using the eXecutive Noise Steering commands:
Temporarily change LFE Setting a non-OFF setting, (0,S,S,14=1;) -12 dB for
example, (so the software believes there is a subwoofer) before using the BKCDIP eXecutive Noise Increment command.
Temporarily change LFE Setting to OFF (0,S,S,14=0;) if subwoofer is not resent
(so the software believes there is not a subwoofer) before using the BKC-DIP
eXecutive Noise Increment command.
(0,X,4,0=1;) Left Front noise on, all others off
(0,X,4,1=1;) Center noise on, all others off
: :
(0,X,4,5=1;) Subwoofer noise on, all others off
Fix:
Upgrade to Version 2.04 or later.

REF 10, Version 2.03
REF 20, Version 2.03
Description:
If the Noise Generator State is set to Off using the BKC-DIP eXecutive Command (0,X,3,0;)
without the Noise generator previously being active, the unit will be muted.
NOTE: Attempts to activate the Noise Generator using the BKC-DIP eXecutive Command
(0,X,3,1;) are ignored if the unit is in Sleep (this is an easy way to created "unmatched"
Noise Gen On/Off pairs).
Work around:
Always send a pair of messages to assure that the noise generator is on before attempting to turn it
off:
(0,X,3,1;) potentially redundant eXecutive noise generator On command
(0,X,3,0;) eXecutive noise generator Off command
Fix:
Upgrade to Version 2.04 or later.

REF 20, Version 2.03
Description:
The Right Rear and Left Rear speaker indices swapped when using the Noise Steering Command
(0,X,4, speakerIndex=onOff … ;cs16).
Work around:
Account for incorrect index response when generating Noise Steering commands:
(0,X,4,3=1;cs16) Index 3 activates Left Rear (instead of Right Rear)
(0,X,4,4=1;cs16) Index 4 activates Right Rear (instead of Left Rear)

AVR 101, Version 2.03
AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
Description:
BKC-DIP Z2 Product ID, system parameter 2Ch, has an incorrect maximum value of 1h (implying
values 0h and 1h are acceptable), when should range be 10h (valid values of 0h through 10h).
This makes it impossible to set Z2 product ID above 1h (product ID 2) via the BKC-DIP interface.
Thus using BKC-DIP, it is not possible to access Z2 Product ID’s 3 through 16.
Work around:
None.
Fix:
Upgrade to Version 2.04 or later.

AVR 305, Version 2.00 – Version 2.04
AVR 307, Version 2.00 – Version 2.04
REF 30, Version 2.00 – Version 2.04
Description:
BKC-DIP Realtime Update events trigger by OSDUpdate and/or FPUpdate are not always
generated when display changes (primarily when fast IR messages are causing display updates,
specifically VOL +/-). This poses problems for applications that need to be synchronized to
reflect the FP or OSD state, as the unit doesn't reliably indicate a state change.
Work around:
Monitor Updates from IR and Front Panel in addition to the OSD and Front Panel Realtime
events. Thus if a Realtime event is not generated the IR/FP command indicates that the displays
have most likely changed.
Fix:
Upgrade to V2.05 or later.

AVR 202, Version 2.03
REF 10, Version 2.03
REF 20, Version 2.03
PT3, Version 2.03
Description:
When updating the tuner frequency via BKC-DIP, an internal variable is not updated. This
variable is initialized to 0 (the lowest frequency setting, i.e. 520 kHz AM and 87.5 MHz FM (for
domestic units)) on factory reset, and updated correctly when using IR commands (including
direct frequency entry and tune +/-). The problem manifests itself when the user then recalls a
preset or tuner channel that is "Open" after previously setting the frequency via RS232. The tuner
"Open" frequency will NOT reflect the last frequency entered via RS232, but instead the last
frequency entered via IR (or if IR has never been used, the factory reset value of 0).
Work around:
Set frequencies explicitly in Preset or Tuner Channel before recalling, thus eliminating issues with
"Open" tuner frequencies.
Fix:
Upgrade to V2.04 or later.

REF 20, Version 2.03 - 2.04
Description:
Updating the Zone 2 Band for the current preset, (0,s,P2=FF,4=band;), does not properly update
the tuner hardware.
Work around:
When updating the Zone 2 current preset Band, also write same value to Zone 1 current preset
Band. Since there is physically only one Tuner shared between the two zones, the hardware is
properly updated via the Zone 1 set command, and the Zone 2 data structure is kept up to date
using its corresponding set command.
Set Zone 2 Band to AM:
(0,S,P2=FF,4=0;) Set Zone 2 current preset Band to AM (as usual)
(0,S,P1=FF,4=0;) Set Zone 1 current preset Band the same as Zone 2
Set Zone 2 Band to FM:
(0,S,P2=FF,4=1;) Set Zone 2 current preset Band to PM (as usual)
(0,S,P1=FF,4=1;) Set Zone 1 current preset Band the same as Zone 2
