CMD CDI-4240 DSSI-SCSI converter - help needed

Hi everybody, during the upcoming weeks, I'm going to migrate my web- and ftp-server from an Alphaserver 4100 to my VAX 4000-300 (running VMS). In order to obtain enough disk space for ftp combined with little energy consumption, I'd like to get to work this decent DSSI-SCSI converter from CMD. Problem is that the only documents, I found on bitsavers, are for the CDI-4000 with a different PCB, having less jumpers and connectors, plus being at different positions than on the board I have. Can anybody give me a little help with the jumper configuration of that thing ? Or better, have docs regarding jumper and connector meanings ? Exact model is : CDI-4240/AF with a LCD display at the front. Help is heavily appreciated and helps making the VAX as the new host for my web- and ftp-server a success !
