NETLINX CONTROL CARDS
The NXC-VOL4 Volume Card provides four discrete volume
control channels with LED feedback. The volume control channels
can be programmed for mono or stereo operation, and balanced
or unbalanced audio connections. It supports programmable
a
udio levels, audio mute, variable ramp speeds and preset levels.
Use the on-board jumpers to set the gain/attenuation (Unity, Pro
level (+4dBu) to Consumer level (-10dBu) conversion, or Consumer
level to Pro level on each channel).

NXC-I/O10
Input/Output Card, 10 Channels
FG2021
The NXC-V
AI4 Analog Voltage Card provides four independent
analog-to-digital inputs and four independent digital-to-analog
outputs, which are controllable over the ICSP network. Each port
can be configured for a variety of DC input and output signals.
STANDARD FEATURES
•
Inputs: Four high-impedance analog DC inputs
• Outputs: Four analog DC outputs (user-configurable)
• D/A, A/D conversion: A/D and D/A converters for analog sampling and
control 8- or 10-bit; user selectable
•
A
vailable input voltages: 0 V to +12 V
• Available output voltages: -12 V to +12 V
• The output voltage may be software-configured for any minimum and
maximum levels between -12 and +12 VDC
•
Maximum output cur
r
ent = 60 mA.
• Over-voltage protection to +28 VDC
External reference: A user supplied external reference voltage can be used to set
the maximum voltage range for the D/A outputs. The full analog output range is
scaled to fit the maximum range set by the external reference.
Output voltage may be set to any level between 0-12 VDC, r

enced to the
exter

ence voltage input and NXC-VAI4 power supply GND.
EXTERNAL REFERENCE INPUT
(EREF - ONE FOR EACH OUTPUT)
• Maximum external reference input voltage = +12 VDC
• Over-voltage protection to +28 VDC
INTERNAL REFERENCE OUTPUT
:
(IREF)
• +5 V reference output, maximum current = 60 mA
• This output is intended to drive a ground-referenced load
