AUTO - the primary unit will automatically connect to the previously discovered secondary units at
power-on.
MANual - the primary will connect to the previously discovered secondary units when it receives a
connection command from the front panel or from

After the secondary unit address configuration, run "Discover" on the primary unit to initiate
communication with all secondary units. After initial discovery, the discovery process does not need to
be run again unless the primary/secondary configuration changes.

Primary/Secondary Programming Considerations
Program the output voltage and current settings of the primary unit the same as you would an
individual unit. Refer to
units are locked; you cannot program the settings of the secondary units.
Set both positive and negative current limits high to allow for up/down programming transient
dynamics. Transient dynamics are mainly a result of DUT capacitance charging currents. Note that the
primary unit's current limit and current setting are automatically proportioned among the paralleled
group according to the current rating of each unit.
Reduce the slew rates to mitigate imperfect voltage programming synchronization. By default, the
slew rates are set to their maximum values.
In current priority mode, set the output current of the primary unit to the desired
value. Set the voltage limit to a higher value than the expected operating voltage of
the unit.
