I am going to assume that the 'scope addresses the

do anything too exotic (actually, I don't think the Thinkjet does
anything that strange). OK....
Set the DIP switch on the interface so that the leftmost switch is down
(this sets it to 'translator' mode) and set a suitable HPIB address on
the other switches (there's a table on the bottom of the 82169 if you get
confused :-). Connect the Thinkjet to the 82169 with a couple of HPIL
cables. Connect the HPIB cable to the other side of the 82169. Connect
power to everything.
Now configure the scope to expect a printer at an address 1 more than you
set on the DIP switches (the _interface's_ address is set by the DIP
switches -- that is to say that's the address you send commands to to
configure the 82169. The HPIL peripherals are assigned subsequent addresses).
Try printing something. If you're lucky it'll work...
I gave it a shot...I can't find any way to tell the scope what address
to use for the printer. When I tell it to print, it says "<HP-IB> No
listeners - Transmission Aborted". I assume this means it can't
directly address an arbitrary HPIB device, only something set to
"listen only"? This is the only time I've used HPIB and had things
not "just work". :)
I can set the scope to talk only, listen only, or talk/listen. In
talk/listen mode it allows me to set its HPIB address, but not in the
other modes.
Any suggestions?
Thanks,
