Dear Colleagues,
DCHV "Frequently asked questions" list is available now in HTML
(http://www.cebaf.gov/~gurjyan/dchv_vhg.html)
and in tex formats (~gurjyan/public_html/dc.tex).
This preliminary edition contains answers to the following questions:

What is Vardan's phone number? ;-)

How I can run the dchv?

How I can access the online manual of dchv?

What if I get tcl error massages trying to execute dchv monitoring or
setting?

What if I don't get any response, so the get_roc_status command just
hangs?

Monitoring of the selected group is giving not correct results, the
results are not for the selected group.

How I can select and deselect the groups?

I had a difficulties to select and deselect the groups. It seems not
always working.

After I set the voltages in to the stand by mode appears the alarm in the
audio system.

Is it necessary to set ON after I selected standby mode?

How I can know what values are set as a V1?

Not always I can get rid of the audio alarm after setting ON the tripped
channels.

What if I will dismiss the parameters package window?

Why the monitoring operation are slower for the group 2 and 4 ( even the
group four is the smallest group)?

Can I use simultaneously DCHV and native CAEN software?

How I can turn DC ON and OFF?

Is there a command line functions to complete the CAEN hardware
operations?

Suggestions are welcome.

Sincerely,
Vardan
