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.

 2 RCA audio jacks

 Jumper blocks to easily adjust signal routing
