767.0. "SCSI connections on 4X models?" by CSC32::S_WASKEWICZ () Thu Jan 30 1997 13:33

    
    I need to update my information regarding Single-Ended vs. Differential
    SCSI for connections of the 4X models of Optical Jukeboxes.
    Specifically, what do these look like?
    
    		 Model	SCSI connection type
    		-------------------------------------
                 RW546	Differential connectors only?
    		 RW551   ???
                 RW552   ???
                 RW555	 ???
    		 RW557   ???
    
    Thanks so much for any help,

Hi Steve,

	Here's the rundown...

S - Slow
Se - Single Ended
F - Fast
D - Differential
Ld - Low Density
Hd - High Density
N - Narrow


RW546 - SND ONLY - 50-pin Ld (Centronics style) (Yuk, I know but...).

RW551/RW552 - SNSe/50-pin Hd AND/OR (user selectable) SND/68-pin Hd.

RW555/RW557 - SNSe/50-pin Hd AND/OR (user selectable) SND/68-pin Hd.
