9. Help Section
• Can I control more than one sign from a central location?
Set different ID addresses. The software will allow you to control up to 255 signs.
• How do I remove the demo message on the sign?
The demo message is permanently programmed into the sign and is designed to run automatically when there
are no other messages programmed by the user. When you program a message onto a page, the demo message
will no longer show.
• How much text can I program onto one page?
You can program up to 210 characters per page. There are 26 pages and 16 graphic pages.
• Will I lose my messages after I remove the power from the sign?
No, there is a built-in battery.
• After unplugging the LED board, I lose TIME and DATE settings. Why?
The battery on the CPU is gone. Replace with a battery with the same specifications.
• I plugged in the sign but nothing appears.
Unplug the power to the LED board and plug it in again. Make sure the power adapter is firmly plugged into the
LED board. Try using another wall outlet. Try resetting the system.
• The sign does not show any message after setting the display by schedule.
Clear the display by schedule and reset the system.
• The software is not communicating with the sign.
Refer to sections “Setup” and “Sending a Message”. Do not extend the 9-pin connection cable with another
cable.
• I receive an “Open COM Error”.
This means the COM port you selected is not available or being used by an internal device in your computer.
Please refer to your computer’s user manual or contact the computer’s manufacturer for more information.
• My laptop computer does not have any COM ports and only supports USB devices.
Some newer laptops do not have COM ports and only support USB devices (refer to your computer’s manual to
check). You will need to purchase a USB SERIAL ADAPTER, a device that will convert one of your available USB
ports into a working COM port. However, Velleman do not guarantee that this device will work with all laptops due
to other devices installed by the user and varying manufacturers’ equipment. Contact the laptop’s manufacturer
directly for questions regarding installation operation.
