Pin-out for RJ12 to Db9 serial cable.

Hi, at the back of the computer on the digiboard backplate there is 8 rj12 connector, there is four of those connectors free…
I want to add to more terminals to this Unix Server. Can you tell me what is the pinout for the DB9 connector.

Could you provide the serial number or model name of this product (can be found on a label on the card itself)? Also, are you sure that isn’t an RJ45 connector on your product?
