SCAN:PORT ABUS

 

CLOS (@100,215)

100 closes channel 00 of card #1;

 

215 closes channel 15 of card #2.

Opening Channels: To open:

 

use [ROUTe:]OPEN (@ccnn) for a single channel;

use [ROUTe:]OPEN (@ccnn,ccnn) for multiple channels;

use [ROUTe:]OPEN (@ccnn:ccnn) for sequential channels;

use [ROUTe:]OPEN (@ccnn:ccnn,ccnn:ccnn) for a group of sequential channels;

or any combination.

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

Open Channels: Opening an already open channel has no effect.

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

*RST Condition: All multiplexer channels are open.
