CLOSe? [ROUTe:]CLOSe? <channel_list> returns the current state of the

channel(s) queried. The channel_list is in the form (@ccnn). The

command returns 1 if the channel is closed or returns 0 if the channel is

open.

Comments • 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).
