    Need some help, anyone having the cable setup diagram for the AP-CBL-SER cable. Expensive to purchase from Aruba.

    You cannot build that cable.  Please look at the thread here:  http://community.arubanetworks.com/t5/Aruba-Instant-Cloud-Wi-Fi/Pinout-serial-for-RAP-155P/m-p/167288/highlight/true#M5851

     

    You will have to purchase it.

    Or, you can do as i did. I had to access the serial on an AP103 and could not get a hold of the propper console cable at the moment. I searched the Airheads community and with the info i could find i sucessfully managed to access the console using a cheap USB-TTL converter i had at home:
    http://www.ebay.com/itm/FTDI-FT232RL-USB-to-TTL-Serial-Converter-Adapter-Module-5V-3-3V-for-Arduino-/321875438143?hash=item4af1456a3f

     

    USE AT OWN RISK!

    I do not guarantee this will work, if done wrong there is a risk that you permanently damage the console port of your AP/RAP!

     

    Spoiler

     

    First set the jumper on the USB-TTL converter to 3.3V! (5V TX signals might damage the console port on the AP/RAP, i have not tested 5V since 3.3V works.)

    Secondly connect cables like this:

    That's it. TTL-USB converters are not really rocket sience, and the Arduiono boom have made the converters really cheap and easy to find.

    The Best Answer back in 2014 is not an appropriate answer in 2023.  These cables are no longer available from Aruba.  I worked with CDW who has contacted Aruba inside sales who told them to go through other 3rd party channels.  It seems that the only option is to build your own.  I have sourced parts on Amazon that may help with getting one built.  This is what I plan to use.   

    https://www.amazon.com/gp/product/B07TXVRQ7V - FTDI FT232RL USB to TTL adapter (voltage selector for 1.8, 3.3v, and 5v). I chose this because it has an insulated package for the electronics.

    https://www.amazon.com/gp/product/B08X6C7PZM - Connectors, Wires, Pins kit for connection cable.  This is to make the 6 pin to 4 pin cable.  

    https://www.amazon.com/gp/product/B08D67L3YS - Cable crimping tool.  Self explanatory.

    Total cost is around $50.

    Patrick,

    Use this for $15.99:

    https://www.microcenter.com/product/454433/adafruit-industries-usb-to-ttl-serial-cable

    Don't connect the power cable (red). It provides 5VDC.

    Thanks,

    Brad

    Also, the logic level for the TX and RX pins are already at 3.3VDC, so you don't need to worry about those.

    As Tamaz cited, you can use a USB TTL adapter, but you can also use a standard TTL-RS232 adapter as well. 

     

    It appears that the PIN out is also the same, VCC, RX, TX, and Ground. 

    VCC on the RAP-3 and the AP-205H appears to be 3.3V. 

     

    Tested with:
