16 Application Note
Chapter 3 Connecting the TFT-LCD to the CPU-1232
This section contains a brief checklist of the actions to perform before connecting a TFT–LCD display to the
CPU-1232.
First of all, download all information about the TFT-LCD module and its inverter selected;
Verify that the resolution of the TFT panel is compatible with and supported by the resolution shown in
Table 1 of this application note;
Read carefully the TFT-LCD datasheet,in particular the Electrical Characteristics that must be
compatible with the electrical interface of the CPU-1232 TFT LCD interface referred to in Table 4;
Consulting the TFT-LCD datasheet and the Table 3 CPU-1232 connector pin-out, write a table with the
connections between the J19 CPU-1232 connector and the TFT-LCD selected; this may be useful when
building the connection cable;
Consulting the TFT-LCD inverter datasheet and Table 3 CPU-1232 connector pin-out, make the proper
cable.
Refer to the TFT-LCD input signal timing datasheet section to detect the parameters to insert into the
CPU-1232 BIOS Flat Panel section and calculate it as described in the Chapter 2 BIOS Setup.
To connect the system, first carefully verify the connections cable, the BIOS settings and all the
information to prevent erroneous damages to the system.
After verifying the information, power up the system verifying all information is properly displayed on the
TFT-LCD module. Try some graphical test programs to detect the functionality of the images.
