How to connect the ProxySG BlueCoat serial interface?

The Digi CM16 is not working with the serial interface of the ProxySG by BlueCoat.
Might be the problem is related to the pin out that, for Digi serial interface, is based on Sun/cisco pinout.
Is there any device/adaptator that can let the connection working?
Is existing a schema of the pinout of Digi Serial interface and ProxySG BlueCoat?

Thanks in adavance for your answers
