OPEN? [ROUTe:]OPEN? <channel_list> returns the current state of the channel(s) queried. The channel_list is in the form (@ccnn) (see [ROUTe:]OPEN for definition). The command returns 1 for channel(s) open or returns 0 for channel(s) closed.

Comments ∙ Query is Software Readback: The [ROUTe:]OPEN? command returns the current software state of the channels 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 Open State

This example opens channels 100 and 213 of a two-module switchbox and queries channel 213 state. Since channel 213 is programmed to be open, 1 is returned.

OPEN	(@100,213)	! Open channels 100 and 213
OPEN?	(@213)	! Query channel 213 state
