CLOSe [ROUTe:]CLOSe <channel_list> closes multiplexer channels specified in the
channel list. The channel_list for
CLOSe is in the form (@ccnn), or in special
circumstances, (@ccnn,ccnn), where cc = card number (00-99) and nn = channel
number (00-15). Before using the
CLOSe command, you must specify the
SCAN:MODE and SCAN:PORT, as these commands determine what switches
will be closed for a given channel. You can only have one closed channel on a
card at a time. If you want to close a channel on two different cards in the same
VXIbus instrument (for example, 102,208) you can use (@ccnn,ccnn).

Comments • Specify SCAN:MODE and SCAN:PORT: Before using the CLOSe
command, specify the SCAN:MODE and SCAN:PORT.
• Closing Channels: To close:
– use [ROUTe:]CLOSe (@ccnn) for a single channel;
– use [ROUTe:]CLOSe (@ccnn,ccnn) for single channels on
different cards;
– use [ROUTe:]CLOSe (@ccnn,ccnn) for multiple channels;
– use [ROUTe:]CLOSe (@ccnn:ccnn) for sequential channels;
– use [ROUTe:]CLOSe (@ccnn:ccnn,ccnn:ccnn) for a group of
sequential channels;
– or any combination.
Closure order for multiple channels with a single command is
not guaranteed.

• *RST Condition: All multiplexer channels are open.
