DB25 cable. Connect the interface to the base of the robotic arm.
Keep the interface off for the time being. If you turned the interface

port may cause the robotic arm to begin performing a function.

Start the program by double clicking the Images icon in the Start
menu. The program’s opening screen is shown in Fig. 15.9. With the
program running, the red LED on the interface should be blinking.
Note: The interface does not have to be turned on for the LED to

in your computer. The blinking light from the LED may be very
dim; you may need to block some room light to see it by cupping
your hands around the LED. If the LED is not blinking, the program
is probably set to the wrong printer port address (LPT port). To set
