000-2072 1250-LTC Installation and Programming Manual
Procedure:
1. Place the CD into the CDROM drive.
2. The installation Wizard should automatically begin to install the program. Click the “Next”
button.
3. Check the installation path. You may change it if desired by clicking the “Browse” button.
Click on the “Next” button.
4. When asked if you are ready to install the application click the “Next” button. Answer the
occasional prompts appropriately. The program will be installed. Click the “Finished”
button when the installation is done.
5. Prepare the 1250-LTC to be programmed through the serial port by entering the
Program Mode:
A) Press the MENU until the display goes blank, then press the SELECT/ENTER
button.
B) Scroll up to OP 51 by pressing the UP button then press the SELECT/ENTER
button.
C) Press the UP button to change the value to “4” then press the SELECT/ENTER
button.
D) Exit the Program Mode by scrolling to OP 0 then press the SELECT/ENTER button
twice.
6. Connect Serial Adaptor Cable provided to the1250-LTC’s Auxiliary connector at the
top-rear of the instrument. The red stripe of the cable must face the outside edge of the
connector. Connect the Serial Adaptor Cable to the computer’s serial port cable. A null
modem adaptor or “nulled” serial cable will be needed. If the computer’s serial port cable
ends with a 9 pin connector, a 9 to 25 pin adaptor will be needed.
7. To run the 1250-LTC Serial Programming Interface, you may create a shortcut to the
program, browse to the file “1250-LTC Serial Programming Interface Rn.nn.exe” with the
Explorer, or select the program from the Start button under the “Programs” folder.
