clrcon

This command opens or de-energizes all device under test (DUT) pins and instrument matrix relays,

disconnecting all crosspoint connections.

int clrcon(void);

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

If any sources are actively generating current or voltage, the devclr command is automatically

called before the relay matrix is de-energized.

pulse_output

This command connects pins and instruments together.

int conpin(int InstrTermID, int connect1, [connectn, [...]] 0);

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

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.
