Hello everyone!
I needed a serial cable for PTN and could not find it, so I decided to make the cable manually, and I wanted to share how to make this cable, maybe someone needs it.
What console interface cable ?
Console cable is used to connect the console interface on the PTN 6900 to the serial
interface of the console to transmit configuration data of the PTN 6900.
the console interface cable is an 8-core shielded cable. One end of the cable is an RJ45 connector
connected to the console interface on the MPU. The other end has DB9 and DB25 connectors,
either of which is connected to the serial interface on a computer.
| RJ45 | Direction | DB 25 pin | DB 9 pin | Signal |
| 1 | ==> | 5 | 8 | CTS (Clear to Send) |
| 2 | ==> | 6 | 6 | DSR (Data Set Ready) |
| 3 | ==> | 3 | 2 | RXD (Receive Data) |
| 4 | 7 | 5 | GND | |
| 5 | - | 8 | 1 | GND |
| 6 | <== | 2 | 3 | TXD (Transmit Data) |
| 7 | <== | 20 | 4 | DTR (Data Terminal Ready) |
| 8 | <== | 4 | 7 | RTS (Request to Send) |
thanks,
