Parallel port & SCSI
This is continuing a thread from 3 years ago, but I have a question
about a scanner of mine. It is a ScanPlus III 300 scanner, and according to the online manual, it has a SCSI interface with a SCSI card included, but looking at the scanner, it appears to have a parallel port interface(right number of pins), including a connector with a printer symbol, presumably for sharing the parallel port. Can anyone explain this seeming contradiction? Here is the link to the manual. http://www.gtcocalcomp.com/CalCompfiles/sp3hdwm.pdf (875 KB) |

Can't tell crap from figure 1.1 in the manual you enclosed about the
scanner. Nor anything else for that matter regarding your question. I might pose a similar question regarding the Microtek E3 scanner regarding all 3 of its ports. Dave wrote in message om...

I have an older HP scanner, and it has a DB25 connector for SCSI.
A DB25 connector is just one standard for SCSI and it is true, a DB25 connector is also used for parallel printer ports. SCSI can also be daisy changed and why there is second DB25 connector on your scanner. wrote: ... it has a SCSI interface with a SCSI card included, but looking at the scanner, it appears to have a parallel port interface(right number of pins), including a connector with a printer symbol, presumably for sharing the parallel port.

I don't think DB25 is standard for SCSI, but it _was_ used, standard or not.

Are you sure that the symbol is a printer and not the SCSI symbol shown
at http://www.nikon-euro.com/nikoneuro_...Q_gen_en_1.htm Yes it is a printer symbol, and I guess it is a passthrough for a SCSI printer then, or perhaps a connection to scan and print directly. Thanks. |

Reading the linked Calcomp Manual, the scanner is scsi model, not a parallel
port model. All he needs is scsi card and scsi cable with proper end connectors for card and scanner. The two ports on the scanner are for connection to the card and connection to any scsi device daisy-chained to it. Herb "Barry OGrady" wrote in message ...

SCSI can also be daisy changed and why there is second DB25 connector on your scanner. His scanner probably connects to a printer port, as mine does. The second DB25 is to allow a parallel printer to be used on the same port. I have a SCSI external hard drive unit that connects to the computer by a printer port. -Barry ======== Web page: http://members.optusnet.com.au/~barry.og Atheist, radio scanner, LIPD information.

Is your SCSI external hard drive actually connected through a printer (parallel) port, or using a DB25 connector? -- Bill Replace "g" with "a" Experience is what you get when you expected something else. |
