entries for a chanlist.
Chanlist

Single channel (Slot 2, Channel 36).
1!6, 1!18, 2!3!6
Multiple channels separated by commas.

Range of channels (2 through 10).
1!2:1!10, 2!3!6
Range entry and single entry separated by commas.
1!30:1!40, 2!1:2!10

first 10 channels on card 2).
1!4!1:1!4!10, 2!1!1:2!4!10
Range of matrix channels (10 columns of row 4 on card 1,
10 columns of row 1 on card 2).
M36

The :CLOSe? <list> query command is used to determine the state (closed or not closed) of each
specified channel. After sending this command and addressing the Model 7001 to talk, the val-
ues for the specified channels will be sent to the computer. A value of “1” indicates that the chan-
nel is closed, and a “0” indicates that the channel is not closed (open).
For example, assume channels 2, 3 and 6 are closed and the following query command is sent:
:clos? (@
1:10)
