Why can't I seem to communicate with COM 3 or COM 4 on my 2800 Series POS system?
- If you have changed any settings that relate to COM 3 or COM 4, it may affect the functionality of these ports. If you return the settings to the original configuration and you are still having problems please contact email@example.com.
- If you have reloaded or changed the Windows operating system, Windows will default the COM port on the PCI serial expansion card to COM 3. This then causes the COM 3 port on the 2800 to be mapped as COM 4, so the physical Windows/hardware mapping would then be:
- COM 3 in Windows is actually COM 4 on the logic module
- COM 4 in Windows is actually COM 3 on the logic module
- You can easily reverse this by going into the device manager properties for each of these ports and then manually change the port assignment in Windows to match the hardware.
Why doesn't the number pad section on my M700 seem to function?
- What typically happens in this case is Windows will remember the last state of the keyboard when booting up. If "Num Lock" was not enabled the last time the unit was powered up it will appear that the number pad on the M700 is not functional.
There are two ways to fix this:
- You can simply hook up a standard PC keyboard to the 2800 and cycle the "Num Lock" key until the LED comes on. When the LED turns on, you can shut down the unit, remove the PC keyboard, and re-connect the M700 series keyboard. Power up and you should have restored your number pad functionality.
- The second solution is to use the Ultimate Technology ULAP application. This software allows you to program any key to do any function on your M700 series keyboard. With a standard PC keyboard in place you can copy the "Num Lock" function and program it onto your M700 series keyboard. You can download this utility here.
