clrcon
This command opens or de-energizes all device under test (DUT) pins and instrument matrix relays,
disconnecting all crosspoint connections.
Usage
int clrcon(void);
Details
The clrcon command is called automatically by the devint, pulse_output (only for RPMs), and
execut commands. The first in a series of one or more connection-type commands automatically
calls a clrcon command. Because this command is automatically called, it is not normally used by a
programmer.
If any sources are actively generating current or voltage, the devclr command is automatically
called before the relay matrix is de-energized.

conpin
This command connects pins and instruments together.
Usage
int conpin(int InstrTermID, int connect1, [connectn, [...]] 0);
The instrument terminal ID, such as SMU1, GNDU, or PMU1CH1
A pin number or an instrument terminal ID
A pin number or an instrument terminal ID
Details
conpin connects every item in the argument list together. If no connection rules are violated, the pin
or terminal is connected to the additional items, along with everything to which it is already
connected.
The first conpin or conpth after any other LPT library call clears all sources by calling devclr and
then clears all matrix connections by calling clrcon before making the new connections.
The value -1 is ignored by conpin and is considered a valid entry in the connection list.
With the row-column connection scheme, only one instrument terminal may be connected to a pin.
