• Closing Channels: To close a single channel, use [ROUTe:]CLOSe
(@ccmmnn); for multiple channels use [ROUTe:]CLOSe
(@ccmmnn,ccmmnn,...) or any combination. Closure order for multiple
channels with a single command is not guaranteed.
• Channel Range: The RF Multiplexer will accept and execute channel
ranges (ccmmnn:ccmmnn) without generating an error, but the result is to
close the last channel in each bank within the range specified. For example,
after CLOSe (@010101:010151) is executed, card 01, module 01 channels
03, 13, 23, 33, 43, and 51 would remain closed.
• Module Number: The module number can be omitted when Expander
modules are not connected to the RF Multiplexer. Module numbers must be
specified when one or more Expander modules are connected to the RF
Multiplexer module.
• Related Commands: [ROUTe:]OPEN?, [ROUTe:]CLOSe?
• *RST Condition: All banks with channel 0 connected to COMmon.
Closing RF Multiplexer Channels
This example closes channels 100 and 202 of a two-card switchbox (card numbers
01 and 02).
CLOS (@101,202)
101 connects channel 01 to COM00 on card #1 and 202
connects channel 02 to COM00 on card #2.
[ROUTe:]CLOSe?<channel_list>returns the current state of the channel(s)
queried. channel_list has the form (@ccmmnn) (see [ROUTe:]CLOSe for
definition). The command returns 1 if channel(s) are closed or returns 0 if
channel(s) are open.
• 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.
Query Channel Closure
This example closes channels 01 and 02 of a two-module switchbox (card number
01, module 00 and 01) and queries channel closure. Since the channels are
programmed to be closed 1,1 is returned.
CLOS
Connect channel 01 to COM00 on the RF Multiplexer
module (00) and channel 02 to COM00 on the Expander
(@10001,10102)
module (01).
CLOS?
Query module 00 - channel 01 and module 01 - channel 02
closure state.
