Many networking devices have an RJ45 console port for administrative access.
| RJ-45 Pin | Signal | Description |
|---|---|---|
| 1 | RTS | Request to Send |
| 2 | DTR | Data Terminal Ready |
| 3 | TXD | Transmit Data |
| 4 | DCD | Data Carrier Detect |
| 5 | GND | Ground |
| 6 | RXD | Receive Data |
| 7 | DSR | Data Set Ready |
| 8 | CTS | Clear to Send |
NOTE: While Ethernet and console ports share the same RJ45 connector they are electrically different and damage may occur if used incorrectly.
