Overview
The Digilent PmodCON4 peripheral module
(the CON4™) connects a 6-pin header to two
RCA audio jacks which can be used to connect
audio equipment.
The CON4 is ideal for adding an RCA audio
connection to an embedded control system or
a programmable logic circuit board.
Features include:
• a 6-pin header connector
• two RCA audio jacks
• flexible configuration of header pins
and RCA audio jacks
• small form factor (0.80 X 1.10).
Functional Description
Pins 1 through 4 can connect to either of the
RCA audio jacks. To connect the 6-pin header
to the two RCA audio jacks, place the shorting
blocks on two of the four jumpers, one using a
J2 pin and one using a J3 pin.
For example, to connect Pin 1 to the J2 RCA
audio jack, place the shorting block on the first
jumper, on the middle pin, and the J2 pin.
Next, to connect the J3 RCA audio jack,
choose another jumper and use a shorting
block to connect the middle pin and the J3 pin.
Pin GD is ground and pin NC is not used. Do
not use more then two shorting blocks or
connect more than one pin to a single RCA
jack as this can damage the system board.
The CON4 has a 6-pin header for easy
connection to a Digilent system board or
Pmod™ module. Since RCA jacks are
normally used to connect to equipment that
produces or receives analog signals, the
CON4 will normally be connected to a Digilent
A/D or D/A converter module, such as the
PmodAD1™ or PmodDA1™. The CON4 is
designed to plug directly into these modules.
Some Digilent microcontroller-based system
boards, such as the Cerebot™, have built-in
A/D converters, and the CON4 can be
connected directly, or via a 6-wire cable, to the
appropriate Pmod interface connector on the
system board.
