Question asked by VRFuser on Aug 8, 2004
How much help do you need?

Lets connect the serial into device.  Assume you are using COM1

Within VEE.I/O|my Configuartion|Find Instruments

Under Serial1 click 'ADD"

Go through all the set-up "jazz" select what you need, if you don't know
check manual for device. Or use defaults.

Check the IO icon in the task bar, right click, and run I/O config

Click the com1 line then edit, make sure the settings are the same as what
you have in VEE

...You may do a read write to the instrument with direct I/O by doing the
following:

Close all "IO" windows, 'cept VEE, make sure nothing is using COM1, but the
device

Within the instrument manager, click the device you added, then click Direct
I/O

Within this box you may do a read write, double click where it says "double
click"

...Play with everything.

If you have a set of scuppie commands try "*IDN", or EXECUTE RESET, and so
forth

Next try a simple command that will produce a result.

After each write try a 30mSec wait (this assumes the instrument does
something before it responds), make sure you set your timeout either within
the I/O Instrument manager, or add an input terminal and set it there.  Try
to sample the shortest timeout with the longest possible expected.  Else
just try 30ms to about 2 seconds for the timeout.  The 5 seconds is usually
far too long, typically if you havn't heard from the device within about
50mSec, you probably won't.

>From here you're on your own.
