Console and Auxiliary Port Signals and Pinouts

Your router comes with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console terminal (an ASCII terminal or PC running terminal emulation software) or modem to your router. The console and auxiliary cable kit includes the following items:

RJ-45-to-RJ-45 rollover cable

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)

For console connections, proceed to the "Console Port Signals and Pinouts" section; for modem connections, proceed to the "Auxiliary Port Signals and Pinouts" section.

Console Port Signals and Pinouts

Use the thin, flat, RJ-45-to-RJ-45 roll-over cable and RJ-45-to-DB-9 female DTE adapter (labeled "TERMINAL") to connect the console port to a PC running terminal emulation software. Figure B-1 shows how to connect the console port to a PC. Table B-1 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL).

You can identify a rollover cable by comparing the modular plugs at the two ends of the cable. When you 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 B-2.) If you purchased your cable from Cisco Systems, pin 1 is white on one connector, and pin 8 is white on the other (a rollover cable connects pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

This section provides information about the 1-port serial WAN interface card. With the appropriate serial transition cable, this card can provide an EIA/TIA-232, EIA/TIA-449, V.35, X.21, DTE/DCE, EIA-530 DTE, or NRZ/NRZI serial interface.

Types of Serial Cables

Six types of serial cables (also called serial adapter cables or serial transition cables) are available from Cisco Systems:

EIA/TIA-232 Interface

EIA/TIA-449 Interface

V.35 Interface

X.21 Serial Cable Assembly

EIA-530 Interface

All serial cables provide a universal plug at the interface card end. The network end of each cable provides the physical connectors most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.

All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector (male) at the network end and DCE with a receptacle (female) at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.

Connecting the Card to the Network


Note The serial WAN interface card uses a universal high-density, 60-pin receptacle. Each universal port requires a serial port adapter cable that determines the port's electrical interface type and mode: DTE or DCE. Although all port adapter cables use a universal plug at the quad serial module end, the network end of each cable type uses the physical connectors commonly used for the interface. (For example, the network end of the EIA/TIA-232 port adapter cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.)


After you install the serial WAN interface card, use the appropriate serial cable to connect the interface card's DB-60 serial port to one of the following types of equipment:

An asynchronous modem, if connecting to an analog telephone line

A synchronous modem, data service unit/channel service unit (DSU/CSU), or other data circuit-terminating equipment (DCE), if connecting to a digital WAN line

EIA/TIA-232 Interface

This section contains the following topics:

EIA/TIA-232 Connections

EIA/TIA-232 Serial Cable Assembly

EIA/TIA-232 Connections

EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The network end of the adapter cable is a standard 25-pin D-shell connector known as a DB-25. (See Figure B-7.) The router console and auxiliary ports also use EIA/TIA-232 connections; however, the serial module ports support synchronous connections, and the console and auxiliary ports support asynchronous connections.

Figure B-7 EIA/TIA-232 Adapter Cable Connectors, Network End

EIA/TIA-232 Serial Cable Assembly

Figure B-8 shows the EIA/TIA-232 serial cable assembly. Table B-8 lists the DTE pinout and Table B-9 lists the DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

EIA/TIA-449 Interface

This section contains the following topics:

EIA/TIA-449 Connections

EIA/TIA-449 Serial Cable Assembly

EIA/TIA-449 Connections

EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions, is a faster (up to 2 Mbps) version of EIA/TIA-232 that provides more functions and supports transmissions over greater distances.

The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard, but it was not widely adopted primarily because of the large installed base of DB-25 hardware and because of the larger size of the 37-pin EIA/TIA-449 connectors, which limited the number of connections possible (fewer than possible with the smaller, 25-pin EIA/TIA-232 connector).

The network end of the EIA/TIA-449 adapter cable provides a standard 37-pin D-shell connector. (See Figure B-9.) EIA/TIA-449 cables are available as either DTE (DB-37 plug) or DCE (DB-37 receptacle).

X.21 Interface

This section contains the following topics:

X.21 Connections

X.21 Serial Cable Assembly

X.21 Connections

The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.

The network end of the X.21 adapter cable is a standard DB-15 connector. (See Figure B-13.) X.21 cables are available as either DTE (DB-15 plug) or DCE (DB-15 receptacle).

Figure B-13 X.21 Adapter Cable Connectors, Network End

X.21 Serial Cable Assembly

Figure B-14 shows the X.21 serial cable assembly. Table B-14 lists the DTE pinout and Table B-15 lists the DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

EIA-530 Interface

This section contains the following topics:

EIA-530 Connections

EIA-530 Serial Cable Assembly

EIA-530 Connections

EIA-530, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller DB-25 connector used for EIA/TIA-232, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully at 4 Mbps or faster speeds over short distances.

The EIA-530 adapter cable is available in DTE mode only. The network end of the EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections. Figure B-15 shows the DB-25 connector at the network end of the adapter cable.

Figure B-15 EIA-530 Adapter Cable Connector, Network End

EIA-530 Serial Cable Assembly

Figure B-16 shows the EIA-530 serial cable assembly, and Table B-16 lists the pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

The EIA-530 interface cannot be operated in DCE mode, and no DCE cable is available for it.

Smart Serial Connection Signals and Pinouts

The Smart Serial cable interface supports two independent serial interface ports. Each port supports six types of serial interfaces: EIA/TIA-232, EIA/TIA-449, X.21, V.35 in both DTE and DCE modes, and EIA530/EIA530A in DTE mode. The serial end of the Smart Serial cable is a 26-pin connector. These cables are used with the 2-port serial and 2-port asynchronous/synchronous WAN interface cards.

Figure B-17 shows the serial transition cables you can connect to the DB-60 port on the asynchronous/synchronous serial modules and serial WAN interface card.
