2-12 Close/Open Switching Module Channels Model 2700 Multimeter/Switch System User’s Manual
Remote programming — system channel control commands
The commands to close and open the system channel are listed in Table 2-1 . When a
system channel reading is returned, the system channel number will be included in the
data string if the CHANnel data element is selected. The FORMat:ELEMents command is
used to specify the data elements to be included in the data string (see FORMat commands
in
Section 14 ).
Reference:
a. ROUTe:CLOSe <clist>
This command functions the same as the front panel CLOSE key (SINGLE menu
option) to select the system channel. Only one measurement channel can be
specified in the <clist>.
Trying to close an invalid channel (such as a non-measurement channel) with this
command will result in error -222 (Parameter data out of range).
b. ROUTe:CLOSe:STATe? <clist>
This query returns a “0” (open) or “1” (closed) for every measurement channel
specified the <clist>. For example, assume <clist> = (@101, 104, 107, 102). The
response message “0, 0, 1, 0” indicates that channel 107 is closed.
The state of non-measurement channels cannot be checked with this command.
