Details
When this attribute is set to open all, channels on all slots are opened before a scan starts.
When this attribute is set to
scan.MODE_OPEN_SELECTIVE
, an intelligent open is performed.
Assuming all steps being scanned have a function value of "
nofunction
" with their DMM
configuration then:
•
All channels and analog backplane relays used in scanning are opened
•
Closed channels and backplane relays not used in scanning remain closed during the scan
If any step has a DMM configuration with a function set to any other value than
"nofunction"
:
•
Analog backplane relays 1 and 2 are opened on all slots
•
Any commonside ohms backplane relays are opened on all slots
•
Any amp channels are opened on all slots
•
All channels and backplane relays involved in scanning are opened
•
If a closed channel or backplane relay is not involved in scanning, it remains closed during the
scan
•
All channels are opened on any bank that contains backplane relays that are involved in scanning
When this attribute is set to
scan.MODE_FIXED_ABR
, it is equivalent to setting
MODE_OPEN_SELECTIVE
, except:
•
All required backplane relays are closed before the start of the scan
•
These backplane relays are not opened or closed during the scan
•
These backplane relays do not open at the end of scan
Example
scan.mode = scan.MODE_OPEN_SELECTIVE
Sets the scan mode setting to open channels
that are used in the scan.
