What happens to the VXI boards plugged into the VXI backplane when a GPIB-VXI/C (p/n 777126) receives DCL from the computer? Do the VXI board reset, or does the GPIB-VXI/C ignore the DCL, or do the VXI boards ignore whatever is transmitted to them, or does something else happen?
Thanks!

Hello,
The DCL message is a universal device clear message that is sent to all devices on the bus and resets them to their "power-on" conditions. For more information please refer to the following links:
GPIB - IEEE 488
ArtisanScientic (Page 19 and 33)
GPIB-VXI/C User Manual (Pages 16 and 191)
Thank you,

Thank you, Simran! The key is from the ArtisanScientic document, page 33.
"When the DCL command is received, the IEEE-488 interface device sends the VXIbus CLEAR command to all VXIbus instruments which are its direct servants."
I knew that DCL cleared IEEE-488 instruments, but I didn't know how to make the connection to clearing the VXI instruments.
Thank you very much.
