Query is Software Readback: The

[ROUTe:]CLOSe?

command

returns the current software state of the channel specified. It does
not account for relay hardware failures. A maximum of 127
channels at a time can be queried for a multi-module switchbox.

Example

Query Channel Closure

This example closes channels 100 and 202 of a two-module switchbox (card
numbers 01 and 02) and queries channel closure. Since the channels are
programmed to be closed 1,1 is returned.

CLOS (@100,202)

100 closes channel 00 of card #1;
202 closes channel 02 of card #2.

CLOS? (@202)

Query channel 02 of card #2.

OPEN

[ROUTe:]OPEN <

channel_list

opens the Microwave Switch channels

specified in the channel_list. The channel_list is in the form (@ccnn)
where cc = card number (00-99) and nn = channel number (00-04).
