Console and Auxiliary Port Cables and Pinouts
Your Cisco VG400 Voice Gateway comes with the cable and adapters you need to connect a PC, an ASCII terminal, or a modem to your Cisco VG400 Voice Gateway. The cable kit includes:
- RJ-45-to-RJ-45 rollover cable
- RJ-45-to-DB-9 adapter cable for console connection
- RJ-45-to-DB-25 adapter cable for modem connection
The following illustrations and tables provide cable pinout information:
- Console port to a PC—See Table A-1 and A-4
- Console port to an ASCII terminal—See Table A-2 and Table A-4
- Auxiliary port to a modem—See Table A-3 and Table A-4
The console port is configured as data communications equipment (DCE); the auxiliary port is configured as data terminal equipment (DTE). Both are asynchronous serial ports and use RJ-45 connectors.
Console Port to PC
Figure A-1 shows the RJ-45-to-RJ-45 rollover cable assembly and the RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL); Table A-1 lists the pinouts.
