Sorry Alan I was editing & lost the post.....!
I'm wondering if I can connect up the Data Express Rhino Jr SCSI caddy / drive on the MX2424 back panel external SCSI connection using an a IDE type molex 4pin from AC/DC 12/5v power adaptor to power the SCSI caddy.

I've attached this old inside picture of a Lacie 68pin SCSI LVD external drive enclosure which has an AC/DC rectifier circuit by the power inlet going to a 4pin molex, the SCSI cable just looks like it's going direct via cable connector to the drive, but there's a also connection for the disk / write LED lights.
Or does the SCSI drive connected to the external MX2424 SCSI connector need to be installed with a SCSI backplane PCB as fitted in external drives to work properly?
I also assuming it also needs a SCSI terminator? The internal SCSI cable has a terminator at the end of the cable so would the same type work on the external SCSI output connection?
I did power up my DE Rhino Jr caddy using an old Firewire external drive (with internal disk unconnected) , using the molex 4pin connector, the light disk number came on & the SCSI drive started up as usual.
Regarding the terminator, do I need a 68pin SCSI cable with a terminator on the end, or is the terminator block for when you have more than 2 external drives in an enclosure?
