with a nominal value of 1K to 10K, are placed on the SCL and SDA communication lines coming from pins
two and three of the Data / Power Connector respectively. Data responses by the module are automatically
output via RS232, in case the host will be querying the module, it is necessary for the host to inform the
module that its responses are to be output via I

• Finally, you may reset the display to it’s default settings using the Manual Override Jumper, see
• The cause of this is often that no font has been loaded onto the display. To load a font onto the display
• Another common cause may be that the contrast settings have been set to low. The solution to this
• First, ensure that you can communicate to the display. A good test is to use a PC, with MOGD#
• Second, unsure that the File System Lock Jumper has not been set. See Section 2.6 on page 9.
• Third, please ensure that the display module’s memory is not full. The GLC24064 has 16 Kb of
