I have a DMC 4123 Box and am using it to drive a large linear actuator ( long movement times ).

My problem is this; Using Java, I am able to load programs ( move point A to point B ) and a small dmc program that interrogates the controller to find where the actuator is ( runs @IN[1..5] statements).

When I run the small program (location program), Java returns the result message quickly and accurately.

When I run a move program, I get a message on the java console "-1100 device timed out" - The following is my code before and after the "XQ" command;

gclib.GTimeout((short) 10000);
gclib.GCommand("XQ"); //execute program that was just downloaded
System.out.println("Executing program");
gclib.GSleep(1000);

I did include "UI" in the dmc code just before "EN"
