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);
InstrTermID
The instrument terminal ID, such as SMU1, GNDU, or PMU1CH1
connect1
A pin number or an instrument terminal ID
connectn
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.
