Have Aspect 3000 computer currently sending output to an HP 7550 Plus
plotter via a DB-25 serial connection. Also have an HP 4000 T laser printer
that understands HPGL-2 plotter language and has a nine pin serial port. Have
HP cable that changes DB-25 to DB-9. The cable pin outs are as follows:
Computer DB-25 Printer DB-9
3 - Receive Data 2 - Transmit Data
2 - Transmit Data 3 - Receive Data
20 - Data Terminal Ready 4 - Data Set Ready
7 - Ground 5 - Ground
6 - Data Set Ready 6 - Data Terminal Ready
5 - Clear To Send 8 - Data Terminal Ready
Have tried connecting the Aspect 3000 to the HP 4000 T using the above serial
cable. When we attempt to send data to the printer, the Aspect 3000
computer makes the attempt and then times out without recognizing the
printer. The printer never indicates that any communication has been
attempted.
Is there a way to get the above equipment connected and working?
Will post summary of responces if useful.
Thank in advance,
Best regards,
Lawrence
