conpth
This command connects pins and instruments together using a specific pathway.
Usage
int conpth(int path, int connect1, int connect2, [connectn, [...]] 0);
path
Pathway number to use for the connections
connect1
A pin number or an instrument terminal ID
connect2
A pin number or an instrument terminal ID
connectn
A pin number or an instrument terminal ID
Details
You can force the system to use a particular pathway by using conpth instead of conpin. This
might be done to provide additional electrical isolation between two connections. The eight pathways
are numbered 1 through 8.
The first conpin or conpth command after any other LPT library call clears all sources by calling the
devclr command and then clears all matrix connections by calling the clrcon command before
making the new connections.
The value -1 for any item in the connection list is ignored by conpth and is considered a valid entry
in the connection list.
The conpth command is not valid in the row-column connection scheme. When the matrix is
configured for remote sense, the only valid path values are 1, 3, 5, and 7.
