A standard twisted-pair Ethernet cable is wired the same on both ends, as shown in Figure B-7 and described Table B-4. Though other wiring color codes are occasionally used, the T-568B color codes shown here are the most common.
Db9 Serial Pinout Color Code
A crossover twisted-pair Ethernet cable is wired differently on each end. Only one end of the cable is wired like a standard twisted-pair Ethernet cable. Though other wiring color codes are occasionally used, the T-568B and T-568A color codes shown in Figure B-8 and described in Table B-5 are the ones most commonly used for crossover Ethernet cables (T-568B on one end, T-568A on the other).
Reference pinout diagrams for DB9 connector (sometimes known as DE9 connector or D-sub connector) for RS232 serial communication ports. RS232 is a serial data communication signalling protocol. D-sub 9pins or 25pins connector is commonly use for RS232. These days RJ45 (or 8P8C) modular connector is also commonly used for RS232 purpose.
A straight-through serial cable is the most common type of serial cable, used to connect a Data Terminal Equipment (DTE) device (for example, a computer) to a Data Communications Equipment (DCE) device (for example, a modem). The pinout of the serial connectors on both sides of the cable are exactly the same with a straight-through serial cable.

This section defines some of the most common connectors and pinouts used in your 'common or garden' type x86 PC circa 2000. All interface wire/cable is different so we have included a handy blank 'color' column so that you mark your wiring code as you work. Are we helpful or what!?
PS/2 = Mini-DIN and the same connector is used for both Mice and keyboards but the pinouts are very different. Beware also that the mouse interface is different for both Logitech and Microsoft (and their compatibles). A 'bus mouse' is not a serial mouse or a PS/2 mouse and is not covered in this section.
Note: The term Serial (for 'Mouse Type') in the table below means a 'good, old-fashioned' serial mouse without any 'combo' capability. Finally we never finished the experiments with the Microsoft Mouse on the KVM so there are a couple of missing sections which we have noted in the text below. Instead we used a standard Logitech mouse on the KVM and let the software auto-detect. Standard MS Serial Mouse pinout.
This section defines the pinout of the PS/2 to serial (DB9) adaptor supplied with a modern Logitech (or compatible) mouse. Note: This adaptor can only be used with a Logitech mice and WILL NOT WORK for Microsoft mice.
The popularity and availability of faster information exchange systems such as Ethernet made the use of null modem cables less common. In modern systems, such a cable can still be useful for kernel mode development, since it allows the user to remotely debug a kernel with a minimum of device drivers and code (a serial driver mainly consists of two FIFO buffers and an interrupt service routine). KGDB for Linux, ddb for BSD, and WinDbg or KD for Windows can be used to remotely debug systems, for example. This can also provide a serial console through which the in-kernel debugger can be dropped to in case of kernel panics, in which case the local monitor and keyboard may not be usable anymore (the GUI reserves those resources and dropping to the debugger in the case of a panic won't free them).
Computers or peripherals which use serial cables for their communication are split into two categories. These are DCE (Data Communications Equipment) and DTE (Data Terminal Equipment.) Data Communications Equipment are peripheral devices such as a modem, or plotter while Data Terminal Equipment is the Computer or Terminal. An RS232 Null Modem cable is used to connect two DTE devices together. The table below provides the connector pinout used on each of a Null Modem cable. A Null Modem cable only really requires three wires; TD to RD, RD to TD, and SG to SG. The other pins may be crossed at each terminating connector [DTR to DSR, CD] and [RTS to CTS]. A LoopBack plug may be constructed by tying TD to RD, DTR to DSR/CD, and RTS to CTS.
The serial port found on a Personal Computer uses either a 9-pin D or 25-pin D connector. The pinout for both those connector types is listed above.This page also lists both of these connector types as they relate to the Personal Computer; RS232 pinout. Serial cables are longer then parallel cables because of the data transmission used.
The RS232 standard does not define a cable, just the cable capacitance and two different forms of connectors.So by definition there is no RS232 color code standard. However there may be an industry standard color code, but there would be no guarantee that a data cable purchased for RS232 usage would conform to a particular color code.
Much of the color coding information found on the internet is based on different equipment using RS232 interfaces. So one page may show one RS232 color code while another shows a completely different one. Of course many pages also may just be copies of some other page. In some cases when an RS232 cable is used to translate to another interface, than that interface standard might be used as the wiring color code for the cable. However, any color coding used with RS232 will be non-standard.
If connecting to a legacy system, or wiring to a design standard use that RS232 pinout color coding scheme. Otherwise use a multiconductor or multipair, shielded or unshielded 'data cable' that contains either 24 or 26 AWG wires and use the color code that comes with the cable. Note the wire color codes normally change with the number of individual wires contained in the cable. A Data Grade Cable is a category of cable.
Adtran uses a female DB-9 configured as DCE. They can be connected via a straight-through DB-9 cable to a laptop serial port but you have to have a "gender changer" to make sure one end of the cable is male (into the Adtran "craft" port) and the other female (into the laptop serial port). To wire a "hood" for use with Cisco console cable standard, use a db-9 male to RJ-45 adapter such as 500-D09-8MK-RD (red in color, from Cabling Systems Warehouse) or Allen-Tel ATDB9M-8 (from Graybar) pinned as follows:
