CNAMPX-16X60 Symbol Input Signal Descriptions
INPUT(S)
DESCRIPTION(S)
Main_Power
This signal activates the main operating power to the CNAMPX-
16X60 circuitry. High/1=power on, low/0=power off.
Rm1 through
Rm8_En
These signals enable (or activate) the audio outputs for the
corresponding amplifier module. High/1 = room is enabled,
low/0 = room disabled.
Enable_Temp_Rpt
This signal selects whether or not the
Temp(x10)
analog
output described in the next table is updated with the CNAMPX-
16X60 enclosure temperature. High/1 = update temperature,
low/0/default = temperature not updated.
Temp_Format
This signal selects the format of the temperature to be
displayed. High/1 = Celsius, low/0/default = Fahrenheit.
This
analog
signal indicates the specific room for which the
audio levels will be displayed. The room number to monitor
corresponds to the value of the analog signal. For example, to
monitor room 1, the value should be initialized to 1. The
default is Room 0, which means monitoring is disabled.
(Although the example program provides only the logic to
monitor rooms 1 through 4, additional logic for rooms 5 through
9 may be programmed.)
Rm_To_Monitor
NOTE:
All outputs listed in the following table are
DIGITAL
signals unless noted
otherwise.
CNAMPX-16X60 Symbol Output Signal Descriptions
OUTPUT(S)
DESCRIPTION(S)
OverRide_F
This signal indicates that the audio output override function is
activated. High/1 = override active, low/0 = override not active.
Rm1 through
Rm8_Amp_Fault
These signals indicate that there is an overcurrent or over
temperature fault within the corresponding amplifier module.
High/1 = fault is present, low/0 = fault present. (There is no
sound when an amp fault is present. It will automatically
attempt to reset after a short duration, attempting to turn the
output on again.)
Rm1 through
Rm8_Wire_Fault
These signals indicate that there is an error with the audio
output wiring (or cables). High/1 = fault is present, low/0 = fault
present. This only occurs after the amp fault has attempted to
reset but fault still exists. This will not reset automatically. (The
room must be turned off, problem resolved and then room
turned on.)
Temp(x10)
This
analog
signal corresponds to the ambient temperature
within the CNAMPX-16X60 enclosure. The temperature reports
approximately once every 2-seconds. (The
Enable_temp_report
entry in previous table must be driven
high/1 for this to update.)
LeftSigLevel &
RghtSigLevel
These
analog
signals correspond to the audio level that is sent
to a room. The specific room is determined by the
Rm_To_Monitor
input signal described in the previous table.
The range of measurement is from 1 to 60 watts @ 8 ohms (0
to 100%). (These signals are for diagnostics and are not VU
meters that function in real time.)
