Digilent PmodCON4 Reference Manual

PmodCON4™ Reference Manual
Revised May 26, 2016
This manual applies to the PmodCON4 rev. B
Overview
The Digilent PmodCON4 allows users to act as a transceiver with two RCA audio jacks.
1 Functional Description
The PmodCON4 is able to route any GPIO based audio signal from one of its four input pins (pins 1 through 4 on
the 1×6 pin header) to either one of the RCA audio jacks via the jumper block present on each of the inputs.
2 Interfacing with the Pmod
The PmodCON4 is able to both receive and transmit audio (or other) signals to one of the two RCA jacks. However,
only one input/output pin can be attached to an RCA audio jack at a time. If two or more are tied to the same jack,
there is a chance that one output will be at a high voltage and the other output at a low voltage, effectively
shorting those two pins and potentially damaging the system board.
