Control Interface Description Document for the Nuvo E6D Main Unit
Revision B
November 26, 2003
DB9M PORT PINOUTS: Nuvo Transmit to System Controller on pin 2.
Nuvo Receive from System Controller on pin 3.
Ground on pin 5.
SERIAL PORT PARAMETERS: RS232, RTS/CTS or software flow control (XON/XOFF) NOT
required, 9600 baud, 8N1 protocol.
RULES OF PROTOCOL:
(1) For alpha ASCII characters, always use UPPER CASE. In this document, actual
characters in a string are presented in BOLD type.
(2) All numerical fields are coded as ASCII digit characters.
(3) Each Command string is STARTED with an ASCII “*” character and terminated by a
<CR> character (0D hexadecimal). Each response string issued by the E6D will START
with an ASCII “#” and be terminated with a <CR> character (0D hexadecimal).
(4) If a command has an error in it (does not adhere to exact command syntax), the E6D will
respond with a “#?<CR>” string.
(5) Whenever queuing multiple commands to the E6D, the host program should pause for 50
milliseconds between commands to prevent buffer overruns.
NUVO POWER-ON STATE:
(1) Each zone is OFF until ON command is received.
(2) Each zone’s ZoneSet status will be as set by the local keypad DIP switches
If no keypad is connected with a given zone address, then ZoneSet will default to:
A. OR0 (No override)
B. BASS+0 (Bass FLAT)
C. TREB+0 (Treble FLAT)
D. GRP0 (SOURCE GROUPING OFF)
E. VRST1 (VOLUME RESET TO –50 dB ON)
If these zone settings are overridden by the commands which follow in this document,
the overridden values will reset to the default values above upon cycling power on the
Main Unit.
(3) For the first four seconds after power-on, a series of non-control related characters will be
issued at a wide range of baud rates. These are necessary queries to a program that
may be running on a connected PC for the purpose of firmware field upgrades. They
should be ignored by the host control system.
NON-VOLATILE COMMANDS AND ASSOCIATED RESPONSES With the exception of
commands associated with setting the IR carrier frequency, the effect of all commands is non-
permanent; i.e. when power is cycled on the main unit, it will return to default values. The
commands that are an exception to this rule follow in this section.
*********************************************************************************
COMMAND: *IRSETSR<CR> – Reads status of SOURCE IR carrier frequency settings.
RESPONSE: #IRSET:aa,bb,cc,dd,ee,ff<CR> where:
aa = IR carrier frequency of SOURCE 1 ("38" or "56")
bb = carrier frequency of SOURCE 2 ("38" or "56")
cc = carrier frequency of SOURCE 3 ("38" or "56")
dd = carrier frequency of SOURCE 4 ("38" or "56")
ee = carrier frequency of SOURCE 5 ("38" or "56")
ff = carrier frequency of SOURCE 6 ("38" or "56")

2
NOTE – the Main Unit ships with the carrier frequency DEFAULT setting of
38 KHz for all six sources.
*********************************************************************************
COMMAND: *IRSETDF<CR> – Restores DEFAULT SOURCE IR carrier frequency settings
(38 KHz for all six sources).
RESPONSE: Same response as for #IRSETSR<CR>
*********************************************************************************
COMMAND: *SxIR56SET<CR> - sets SOURCE x to 56 KHz IR repeat carrier (x is 1 to 6).
RESPONSE: Same response as for #IRSETSR<CR>
*********************************************************************************
COMMAND: *SxIR38SET<CR> - sets SOURCE x to 38 KHz IR repeat carrier (x is 1 to 6).
RESPONSE: Same response as for #IRSETSR<CR>
*********************************************************************************
COMMAND/RESPONSE DESCRIPTIONS.
NOTE – zone number field xx should ALWAYS
Include a lead zero (“0”) for zone numbers less than 10.
COMMAND: *ZxxCONSR<CR> - Connect STATUS REQUEST where xx is zone # from 1 to
12.
RESPONSE: #ZxxPWRppp,SRCs,GRPt,VOL-yy<CR> -ppp = “ON” (2 characters)
or “OFF” (3 characters)
-s = SOURCE NUMBER 1 to 6
-q = 0 if SOURCE GROUP is ON
1 if SOURCE GROUP is OFF
-yy = level below max in dB: -00 to -79 dB
(include lead 0 for all single-digit values)
-yy = “MT” if in MUTE state
-yy = “XM” if external MUTE is being held
active
This response will also be issued in response to pressing the ON/OFF, VOLUME, or SOURCE
keys on a KEYPAD. NOTE – the response will be issued if a SOURCE key is press`ed on a
zone that is powered OFF even though the key press has no effect on the system. It will be
output at every increment during a volume ramp initiated by HOLDING a VOLUME UP or
VOLUME DOWN key on a keypad. It will also be issued at every increment of a volume
ramp commanded by the *ZxxVOL+<CR> and *ZxxVOL-<CR> commands (see below).
The MUTE value will be asserted if a *ZxMTON<CR> command has been received, OR if the
volume is run all the way to the lowest possible point (volume off). An active EXTERNAL
MUTE input, however, will always override other volume response values with the “XM”
response.
*********************************************************************************
COMMAND: *ZxxSETSR<CR> – ZoneSet STATUS REQUEST where xx is zone # from 1 to
12.
RESPONSE: #ZxxORp,BASSyy,TREByy,GRPq,VRSTr -p = 1 if DIP switches are
overridden*
0 if DIP switches are in control

3
-yy = EQ level, dB, –8 to +0 (flat) to
+8 in 1 dB increments
-q = 0 if SOURCE GROUP is ON
1 if SOURCE GROUP is OFF
(This follows DIP switch definition.)
-r = 0 if VOLUME RESET is ON
1 if VOLUME RESET is OFF
(This follows DIP switch definition.)
*override set to 1 FOR THIS ZONE only if one of commands *ZxxBASSyy<CR>,
*ZxxTREByy<CR>, *ZxxGRPq<CR>, or *ZxxVRSTr<CR> are issued (see descriptions
below).
Once it is SET by one of these commands:
a. It will remain set until power is cycled on the unit.
b. Non-address DIP switch changes on a connected KEYPAD connected to this zone
will be ignored.
If override state is “0”, this response is also issued whenever non-address KEYPAD DIP switches
are changed.
*********************************************************************************
COMMAND: *ZxxON<CR> – Turn zone xx ON.
RESPONSE: Same response as for *ZxxCONSR<CR>
*********************************************************************************
COMMAND: *ZxxOFF<CR> – Turn zone xx OFF.
RESPONSE: Same response as for *ZxxCONSR<CR>
*********************************************************************************
COMMAND: *ALLOFF<CR> – Turn ALL zones OFF.
RESPONSE: #ALLOFF<CR>
This RESPONSE is also issued when ALL OFF is pressed on any KEYPAD.
*********************************************************************************
COMMAND: *ALLV+<CR> – Ramp ALL zones UP at a 10 dB/second rate in 1 dB steps.
RESPONSE: #ALLV+<CR>
The ramp action will be cancelled when all zones reach MAXIMUM volume, or when an
*ALLHLD<CR> Command is received. Note that to stop the ramp with this command before
maximum volume, one reference zone must be periodically polled with a *ZxxCONSR<CR>
Command to determine when the desired volume point has been reached. Note that ramps in
different zones may start at different levels and will all ramp at the same rate.
*********************************************************************************
COMMAND: *ALLV-<CR> – Ramp ALL zones DOWN at a 10 dB/second rate in 1 dB steps.
RESPONSE: #ALLV-<CR>
The ramp action will be cancelled when all zones reach MINIMUM (OFF) volume, or when an
*ALLHLD<CR> Command is received. Note that to stop the ramp with this command before the
minimum volume, one reference zone must be periodically polled with a *ZxxCONSR<CR>
Command to determine when the desired volume point has been reached. Note that ramps in
different zones may start at different levels and will all ramp at the same rate.
