CAT-5 Ethernet Cable Standards & Pin-out Assignments

How to Wire Your Own Cables

Industry Standard CAT-5 Pin-out

The images below depict the cable pin-outs for straight-through and cross-over Cat-5 Ethernet cables that conform to EIA/TIA industry standard for 568 A and B. IF the first and second pin are orange, the cable is 568B. If the first and second pins are green, the cable is 568A. If one end of the cable is A and the other end is B then you now have a cross-over.

Symptoms associated with incorrect wiring include:

  • No connectivity
  • Radio not negotiating correctly
  • Needing to be set to 10 Half Duplex (HDX) or 10 Full Duplex (FDX)
  • Connectivity to the radio only at a very short distance

  1. Use the programming cable (CBLDAT-1) supplied with your Access5800 or Access5830 AP and TrangoLINK-10 to connect to the RJ11 port of the radio to the serial port of the PC.
  2. Run a terminal emulation program, such as HyperTerminal™
  3. Set the communication parameters as shown in the following table:
    Parameter Value
    Baud Rate 9600
    Data Bits 8
    Stop Bits 1
    Parity None
    Flow Control none
