Shimadzu CBM-20A - Allocation with [Auto] Selected; Allocation with [Fixed] Selected

3. Preparation
3-12
CBM-20A/20Alite
 Allocation with [Auto] Selected
The pumps are given letters A, B, C, and D in order of increasing link address. The detector
and oven names are also assigned in the same way. If the CBM-20Alite is incorporated in an
LC-30A/20A-series solvent delivery module, this delivery unit will always be pump A.
 Allocation with [Fixed] Selected
Select [Fixed] to fix the relationship between all the components in the system. For example,
with [Auto] selected, if there are 2 detectors and the power to detector A is turned OFF, then
detector B is automatically recognized as detector A. In the same way, if there are 3 pumps
used and the power to pump A is turned OFF, then pumps B and C are automatically
recognized as pumps A and B. This makes it necessary to change existing parameter and
program settings.
With [Fixed] selected, however, detector B continues to be recognized as detector B even if
the power to detector A is turned OFF. In the same way, pumps B and C continue to be
recognized as pumps B and C even if the power to pump A is turned OFF. The oven names
are also assigned in the same way as pumps or detectors.
The default setting is [Auto].
