Description
There is a list of relays considered unused or “not there” by the firmware.
Unused channels are not driven even if included in a channel list or path and
are not checked for proper sense line state and cannot generate errors.
Turning
:DRIVE:OFF for a channel adds it to the Unused List.
NOTE In systems without CMOS RAM it is necessary to execute a write to
EEROM to ensure that the
DRIVe data will survive a power cycle. Refer to
the
MEM:SAVE command.
Example Command • ROUTe:DRIVe:ON (@101,103,105);
This command removes channels 1, 3, and 5 on card 1 from the Unused List.
• ROUTE:DRIVE:OFF (@101,103,105);
This command adds channels 1, 3, and 5 on card 1 to the Unused List.
• ROUTE:DRIVE:OFF ATTEN_14;
This command causes the set of relays (defined by the ROUTe:PATH
command) with name ATTEN_14 to be added to Unused List.
If the path includes two channel lists, all relays in both lists are affected.
• ROUTE:DRIVE:ON:ALL;
This turns drive on for all channels.
• ROUTE:DRIVE:OFF:ALL;
Drive is turned off for all channels; that is, all channels are “unused”.
