Connector Interface:
| Single-ended output | Negative pin is connected to ground. |
|---|---|
| Single-ended input | User’s ground must be connected to the negative pin. |
| Differential output | Positive and negative signals must be on positive and negative pins. Differential input: connection must be between the positive/negative pair. |
