trouble interfacing an HP86B to an HP7040 plotter with a serial interface

9 Sep 2003

Hi,

I am having trouble interfacing an HP86B to an HP7040 plotter with a serial
interface.

I have two HP serial interfaces: standard with male DB25 connector and
0pt.01 with female connector.

The plotter has a male DB25 connector.

I have connected the standard with with a gender changer and the opt. 01
directly without success.

I typed PLOTTER IS 10 and (the baud rate on the plotter is set at 9600)I get
an error message.

This is the first time I have tried a serial connection and unfortunately I
don't have any
documentation for the HP serial interface.

Do I need a null modem for the opt. 01 serial interface?

What am I doing wrong?

Thanks,

Bob
