BLACK lead to GND.
NOTE The Manufacturer’s Warranty becomes void if the unit is subjected to over-voltage
or reversed polarity.
3. Connect the display to the PC using the serial cable and adapter if required.
4. Connect the power connector, making sure that the +5V goes to V+ as shown in the diagram.
5. Turn on the power: the backlight should come on.
1.7 Trying out the GLK12232-25-SM
Ensure the unit is connected to power and the PC and backlight are on.
1. Use the mogd.exe program to exercise some of the features of the display. This should provide an
indication of any malfunction.
2. To experiment with typing text, run a PC terminal program such as Hyperterm. Make sure it’s config-
ured to use the correct port. Set the baud rate to 19,200.
If characters are typed on the keyboard, they should now appear on the display screen. Please note that CR,
backspace, etc., won’t have any effect. Text will wrap around to the next line when the end of a line has been
reached.
