Console and Auxiliary Port Cables and Pinouts

Your Cisco MC3810 series concentrator comes with the cable and adapters you need to connect a PC, an ASCII terminal, or a modem to your Cisco MC3810. The cable kit includes:

•RJ-45-to-RJ-45 rollover cable (see the "Identifying a Rollover Cable" section for more information)

•RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL)

•RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL)

•RJ-45-to-DB-25 male DCE adapter (labeled MODEM)

You can also make your own cable assemblies and obtain your own adapters. The following illustrations and tables provide assembly drawings and pinouts for these cables and the adapters:

•Console port to a PC—See Table A-1 and Table 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.

Identifying a Rollover Cable

You can identify a rollover cable by comparing the modular plugs at the two ends of the cable. Hold the plugs side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure A-1.) If your cable came from Cisco Systems, pin 1 is white on one plug, and pin 8 is white on the opposite plug (a rollover cable reverses the wire connections at the opposite ends: 1 to 8, 2 to 7, 3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, 8 to 1).

Console Port to PC

Alternative Connections to Terminal and Modem

Your Cisco MC3810 series concentrator comes with an RJ-45-to-RJ-45 rollover cable and three adapters for connection to a PC, a terminal, or a modem. If you want to use an RJ-45 straight-through cable or other companies' adapters, see Table A-4 for usable cable and adapter combinations.

Table A-4 Alternative Terminal and Modem Connections

Cisco MC3810 Port Connection	RJ-45 Cable Type	Adapter
Console port to PC	Straight-through	DCE, DB-9 female
Console port to terminal	Straight-through	DCE, DB-25 female
Auxiliary port to modem	Rollover1	DCE2 , DB-25, male
	Straight-through	DTE2, DB-25, male

1 An octal cable or RJ-45 breakout cable is equivalent to a rollover cable. 2 Modify the DB-25 adapter by removing pin 6 and placing it into the pin 8 position.

Serial Cable Assemblies and Pinouts

The following illustrations and tables provide assembly drawings and pinouts for the EIA-530 DCE, EIA/TIA-232, EIA/TIA-449, V.35, and X.21 DTE and DCE, and RS-366 ACE cables. These cables are used with the synchronous serial ports, labeled SERIAL 0 and SERIAL 1.

---

Note These serial cables have a DB-60 connector on the Cisco MC3810 end. Because of the small pins on the DB-60 connector, manufacturing and soldering these cables yourself might be very difficult and is not recommended.

Figure A-14 shows the RJ-1CX connector wiring for analog voice-port cables that are used with 2-wire or 4-wire interfaces with separate signaling paths (E&M interfaces, from "ear and mouth"); Table A-20 lists the pinouts for E&M voice ports. Use an eight-conductor, straight-through cable with RJ-1CX modular connectors for connecting these ports to terminal equipment.

For four-wire E&M connections conforming to ETSI CTR17, use the CTR17 adapter to connect the eight-conductor, straight-through cable to the E&M port. Table A-21 lists the pinouts for the CTR17 adapter.
