vrf I'm a new Vee user..trying to connect to a HP34970a

Question asked by henry.coles on Apr 6, 2006
Hello Vee experts,

I just got Vee 7.51 and I'm in the process of trying to write a "driver"
to get 8 to 10 thermocouple temperatures with say 1 second scans from an
HP34970a which is a multichannel recorder, I guess you could call it.
Of course I can start by just getting one temperature one time.  My
thought is that the most common device anyone would connect to would be
the HP34970a, but that's just a guess.

So far I only have an RS232 connection to the device.  I think I need to
use Direct I/O to talk to it.  I have programming book for the device
and have tried to send a "*IDN?" or "IDN?" to the device to see if I can
get something back.  I got a bunch of syntax errors/etc. just entering
the first Write line.  It does look like Vee sees the device on the end
of the #1 RS232 port.

It looks like a panel driver can only be used if I have an HPIB
connection which I don't have and can't quite figure out the VXIplug and
play.....so I'm down to trying the direct I/O approach.

Any help appriciated.  Sorry for the newbee run around.  Maybe there is
a file or old email someone can send me to help out.

Thanks very much in advance.

-Henry
