HP 7550A manual or help wanted

Archived from groups: comp.sys.hp.hardware (More info?)

Peter,

HP-IB address 31 is the listen always setting. This may be indicated on
the control panel as Listen Only under the HP-IB address setting.

The interface would be selected from the control panel. However, I think
the plotter is listening on all interfaces. You just need to set the
HP-IB address.

I have a manual somewhere around here. If you have specific questions,
just ask.

Later,

The force setting is determined from the carousel type. Use a carousel
for the type of pens you have.

In other words, if these are the short felt tip pens, use a paper pen
carousel.

The force can be manually set using the speed and force settings on the
display. Force "2" is for paper pens, "1" for drafting and "6" for
rollerball. This can be set once for ALL pens or for each pen individually.

Note: a power cycle, plotter init command or carousel change will revert
all setting to match the carousel.
