Installing the Software

This section describes the installation and configuration of the 212-LC
driver with the MSWS control software and gives a brief overview of its
functionality.
The 212-LC System is controlled by MSWS over a single serial
connection. The PC is connected to Pump A, commands for Pump B are
routed through Pump A.
MSWS control does not use the native 212-LC method. MSWS 212-LC
Methods are executed in the driver, and simple flow commands are sent
to both pumps.
The 212-LC MSWS Method can contain up to 100 steps specifying flow
and composition, with a time resolution of 1 second. The method always
executes a linear ramp of flow and composition from one step to the
next.
Optional ramps on activation and completion specify a ramp duration and
a hold time. This can be used to avoid abrupt pressure changes and/or
provide an equilibration time after a composition change.
The user interface is similar to that of the Dynamax System driver. The
System Control driver provides a view of the composition program and
the pressure reported by each pump.
A GLP section is included in each data file produced by the instrument
containing the 212-LC. This section documents the pump serial
numbers, the firmware versions, the solvent names and compressibility
factors used, and a set of pump stroke counters for consumable items
with their service date.
The 212-LC Control Software is available for MSWS 6.60 SP1 and later
versions. For MSWS 6.7 and later, a 212-LC driver is already included
with the LC Module drivers, which are installed if you select the 500-MS
or 1200 LC/MS option during installation.
If the installed MSWS is 6.7 or later, skip the following step.
For a system with MSWS 6.6 SP1 installed, please proceed as follows
•
Close all MS WS applications including System Control,
Method Editor, and the Workstation Toolbar.
•
Insert the CD provided with the pumps, labeled "212-LC
Control Software Update for MSWS 6.6 SP1".
