AP-CBL-SER serial console pinout (AP103 and many others)

    Maybe it will make a few life easier. I have seen some confusing posts on this subject.

     

    This is a correct pinout of AP-CBL-SER serial console cable for IAP-103 and many more APs. Instead of buying ridiculously expensive Aruba cable, do it your self.

     

    All you need is:

    - TTL (pins) to RS232 (DB9f) adapter (approx. 1 EUR), keep in mind that adapter should work with 3.3-5v voltage range, not more! I used Arduino platform adapter to DB9 female.

    - 4 wire cable (even 3 should work, without VCC).

     

    See attached picture.

    Hi!


    FYI: Newer APs, like 203R, are using Micro-USB for the TTL-Serial connector.

    The right Aruba-Cable is JY728A -  AP-CBL-SERU.

     

    It's an active cable, which has an integrated USB to Serial/TTL-3.3 Volt  converter. (not comparable with RS232 Serial).

     

    Pinout of the TTL-Port of AP is:

    • PIN 1 (USB Vcc, red) --> Do not connect (USB converter get's powered by USB of PC)
    • PIN 2 (USB Data-, White) --> TTL Receive (Cross to TX)
    • PIN 3 (USB Data+, Gren) --> TTL Send (Cross to RX)
    • PIN 4 (USB ID) --> Do not connect
    • PIN 5 (USB GND, Black) --> Connect to GND

    Refer USB Pinout: https://en.wikipedia.org/wiki/USB_hardware#Pinouts

     

    I'm using this Module https://de.aliexpress.com/item/32893637666.html 


    Connect with 9600baud, 8N1
