2.4 General Purpose Outputs
General Purpose Output, which can provide up to 20 mA of current and +5Vdc from the positive side of the
GPO. If the device, which is being driven by a GPO, requires a relatively high current (such as a relay) and
has an internal resistance of its own greater than 250 ohms, then the 240 ohm resistor, which is associated
with the GPO may be removed and replaced with a Jumper.
2.5 Manual Override
particularly helpful if the display module has been set to an unknown baud rate or I
you are no longer able to communicate with it. If you wish to return the module to its default settings you
must:
Matrix Orbital
1. Power off the display module.
2. Place a Jumper on the Manual Override pins.
3. Power up the display module.
4. The display module is now set to its default values listed below in
5. Edit and save settings.
A unique feature of the LCD2041 is the ability to control relays and other external devices using a
The Manual Override is provided to allow the LCD2041 to be reset to factory defaults. This can be
WARNING If connecting a relay, be sure that it is fully clamped using
a diode and capacitor in order to absorb any electro-motive force (EMF)
which will be generated.
