Configuration and Operation
To begin using your MX1ADS LCD module you must connect the 34 conductor
ribbon cable (RE11057C) that came with your MX1ADS between connectors
J11 on the LCD module and P8 on the MX1ADS main board.
Warning: Be sure input power to the main board is disconnected or switched
off before the LCD module is connected. Connecting the module with power
applied could damage the LCD module and/or the main board.
Your TFT LCD module has two variable resistors that allow users to vary the
contrast, sometimes described as view angle, and the brightness of the FL
backlight. Adjustment of VR1 will change the contrast and VR4 controls the
backlight brightness. These potentiometers are recessed below the Plexiglas
cover. You will need to use a suitable flat head or phillips head screwdriver to
adjust them. This may be done with power applied but caution is advised when
using a metal tool. A plastic bladed tools is recommend. While these controls
were set at the factory, adjustment may be required to suit the user’s
preferences.
2.5.2 Using a SODIMM Card
This connector provide a way to add new circuit boards that may be developed
in the future. Users can also develop compatible DIMM cards as well.
Caution should be used when developing such boards to avoid addressing
conflicts with peripherals that already exits on the main board.
Warning: To avoid circuit damage, do not plug in SODIMM cards with power
applied to the board.
2.5.3 Using a SIM, SD/MMC, or Memory Stick Card
The users must obtain their own compatible cards for use with these connectors.
Please note the power is connected to VCC which is 3.0-volts when using the
power supply provide with your kit.
Warning: To avoid circuit damage, do not plug in SIM, SD/MMC, or Memory
Stick cards with power applied to the board.
