Relay Matrix Switch Command Reference 51Chapter 3

Closing Channels (E1469A Only):

• For a single channel, use [ROUT:]CLOS (@ssrrcc)

• For multiple channels, use [ROUT:]CLOS (@ssrrcc,ssrrcc,...)

• For sequential channels, use [ROUT:]CLOS (@ssrrcc:ssrrcc)

• for groups of sequential channels use [ROUT:]CLOS

(@ssrrcc:ssrrcc,ssrrcc:ssrrcc).

You can use any combination of these commands. However, closure

order for multiple channels with a single command is not guaranteed.

Related Commands: [ROUTe:]OPEN, [ROUTe:]CLOSe?

*RST Condition: All channels open.

Example Closing Relay Matrix Switch Module Channels

This example closes channels 10100 and 20013 of a two-module

switchbox (card numbers 01 and 02).

CLOS (@10100,20013)

!Close channels 10100 and

!20013. 10100 closes row 01,

!column 00 of card #1 and 20013

!closes row 00, column 13 on



!card #2.

[ROUTe:]CLOSe?

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

channel(s) queried. channel_list has the form (@ssrc) or (@ssrrcc) (see

[ROUTe:]CLOSe for definition). The command returns 1 if channel(s) are

closed or returns 0 if channel(s) are open.

Comments Query is Software Readback: The [ROUTe:]CLOSe? command returns

the current software state of the channel(s) 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 Closures

This example closes channels 10100 and 20013 of a two-module

switchbox and queries channel closure. Since the channels are

programmed to be closed, 1, 1 is returned as a string.
