with a test configuration that will cycle the air cylinder 10 times per second. Press the
Start button on the Control Unit to cycle the cylinder. Press Stop when satisfied that the
setup is functional.
To configure the LCTS to test your specific device, it must be connected to the personal
computer (PC) running the software application provided. Attach the 9-pin adaptor to
either end of the 20 foot serial cable with modular connectors (both provided). Attach the
other modular connector of the serial data cable to the serial data connector (figure 1) on
the back of the Control Unit. Plug the 9-pin adapter into any active RS232 serial
communications ports on your PC.
When the software application starts, it automatically starts searching for the LCTS on
all available serial channels between COM1 and COM8. There is a status bar of
information at the bottom of the main window for the application. While searching, the
information will indicate what channel it is testing. When the LCTS is found, there is a
brief message stating that the tester was found on a specific communication channel.
The status bar will then display the serial number, resistance test range and mode, as
well as the software version of the LCTS.
If the software cannot detect the LCTS, verify the serial data connection. Be certain that
the LCTS is powered (power indicator illuminated). If the LCTS still cannot be detected,
the serial communications ports on your PC may be suspect. Load the software on
another PC and test the setup.
This completes setup of the LCTS. Review Section 3 for an understanding of how the
LCTS tests switches. Read Section 4 to learn how to configure and use the LCTS using
the application software.
