Operation Overview
5
This chapter provides an overview of the MDXII unit's operational functions and settings to
give you an understanding of their purpose and use before you perform the operations.
Information on using these functions and settings is described in other parts of this manual, as
follows:
• "Control Panel Interface" on page 6-2
• "User Port Connection" on page 9-1
• "Serial Port Connection" on page 7-1
Table 5-1 on page 5-22 is a reference summary of all the MDXII unit's functions and settings,
including page numbers where you can find out how to access and change or monitor these
operations from the control panel or through the User port or serial port interfaces.
Also read "First-Time Operation" on page 5-27 before you operate the MDXII unit for the first
time.

OUTPUT REGULATION

You can select the method of output regulation from any active interface—you do not have to
perform this function from the control panel menu.
You can choose one of the three methods of output regulation (power, current, or voltage) at
any time without disturbing the output level.
You can program an output level (up to the unit's maximum rated output) for power, current,
or voltage, depending on the method of output regulation you select. "Output Setpoint Level"
on page 5-3 explains how to program output level. Since setpoint levels are stored in
nonvolatile memory, you can use them to recover from input power interruptions and to ensure
repeatability from run to run.
If you switch from one method of regulation to another while output is on, the corresponding
setpoint level becomes the new setpoint. For example: if the MDXII unit is regulating power,
and the setpoint level is 1500 W (voltage level is 500 V and current level is 3 A), and you
select voltage regulation, the new setpoint will be 500 V.

Power

Select power regulation from the control panel by pressing the POWER switch.
Through the serial port interface, use Command 3 to select power regulation.
Through the User port interface, pin 6 (P REG.D) must be low and pin 5 (I REG.D) must be
high.
