Revision E (for Nuvo E6D Mark II systems only) June 8, 2006
Nuvo Transmit to System Controller on pin 2.
Nuvo Receive from System Controller on pin 3.
Ground on pin 5.
RS232, RTS/CTS or software flow control (XON/XOFF) NOT required, 9600 baud, 8N1
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 “
string.
(5) Whenever queuing multiple commands to the E6D, the host program should pause for 50 milliseconds between
commands to prevent buffer overruns.
(1) Each zone is OFF until ON command is received.
(2) Each zone's ZoneSet status will be as set by the special key combination settings as detailed in the owner's manual.
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.
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: Reads status of SOURCE IR carrier frequency settings.
RESPONSE: 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")
