CAN via DE-9 connectors; any standard?

Hi all,

I have a CAN to RS232 converter with female DE-9 connectors to both.

I want to connect into an existing CAN hub on a production line and capture a load of the data. The CAN hub also has DE-9 connectors.

The question is; is there any standard (or 'usual') pin assignments for CAN via DE-9 connectors? I.e. am I likely to be able to connect the converter to the can hub just using a standard straight though serial cable?
