SYSTem:PRESet, *RST, SYSTem:CPON and Power On

These actions drive the channels to their defined DEFault state (using the configuration stored on the remote module) and force the system to recognize new topologies (caused by power or connectivity changes). These actions set the defaults shown in the table on page 152. Two parameters are controllable to ensure safety of operation in the system; the default state for channel closure and the default state for drive enabled.

The default channel state (open or closed) for each channel can be set using either of the following commands.

ROUTe:CHANnel:DRIVe:CLOSe:DEFault

ROUTe:CHANnel:DRIVe:OPEN:DEFault

NOTE

If a channel is configured for a single drive in pulsed mode, OPEN

operations are undefined. When these channels are configured to a

 

 

default state of OPEN, no action is taken on these channels.

 

 

The drive state can be set as a default using the ROUTe:RMODule:DRIVe:SOURce:BOOT command. This command allows you to specify whether the drive current, when present, should be applied to the switches or not. You can set OFF, INTernal, and EXTernal for the default.

The *RST command forces a re- evaluation of all connected remote modules, followed by setting all channels to their default states. This is very similar in operation to what occurs at power- up.

ROUTe:RMODule:BANK:PRESet

This command sets a bank to default values that vary according to which distribution board is attached. The following table shows the default states set by ROUTe:RMODule:BANK:PRESet.
