J19 TFT Digital Interface connector pinout
For physical correspondence with the J19 connector pins, please refer to Figure 1.
The purpose of the information shown herein is to help the user properly build the cable for connecting the
digital interface of the CPU-1232 with a TFT LCD Panel.
Reducing the cable length will reduce interferences to the TFT LCD digital signals.
