I need the pinout for cable **0G2001.00-090**. I found that this cable is no longer manufactured, and I have been unable to find any documentation specifying its pinout. I need this information to perform tests with an **NC154** device. ---

Hi @Isaac_Lopez , I didn’t found the pinout but in the manual it’s written RS232 communication: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/a/abd9bd08c43ee0f789f19345a16b2433d6948709.png) ==== From the CPU - CP152 and CP153 manual ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/a/ac81cb0914631562cdd0f5f598f407abcf81b342.jpeg) I have found more details about [Datasheet RS232 cable | B&R Industrial Automation](https://www.br-automation.com/en/downloads/accessories/cables/datasheet-rs232-cable/): ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/5/5efe50377662618f7d20d7a201863dddf30115c4.png) or standard RS232 cable: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/f/fb15f0421ac24ee7a3bc59ea536e9dd00fe0c3b7.png) Ciao Valerio ---

Hi, I also found no pinout documentation. Asking AI, I was lead to a webpage containing following information which makes sense in my opinion: - There’s no RJ11 serial data standard - try to measure out GND, TX, RX if nobody finds a pinout documentation or knows it - Power off. Do any wires make low resistance connections with device chassis? Label as possible grounds. - Power on. Is any line at -5 to -12V wrt chassis ground. If only one this is probably TXD. - check those probably combination against diagrams found in the internet - it seems that most commonly the combination of RJ11 - 2 GND, 3 TXD, 4 RXD or RJ11 - 4 GND, 2 TXD, 5 RXD were used (but please measure before!) Hope someone will have more reliable information. Best regards! ---

We created this image with the precise pinout of this cable. As you see, the cable only includes 5 internal cables inside + 2 bridges, one on each side. I think this is pretty clear so: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/f/f08d1fd48decc2c918cef4ce69ec6b8d26f39792.png)
