HSYNC and VSYNC signals are squared pulses of +5V, and the RGB signals take values in a continuous analog voltage range from +0V (absolutely dark) to +0.7V (maximum brightness).\\
=== Connection ===
H-Sync -- 68 Ohm -- Pin 03\\
V-Sync -- 68 Ohm -- Pin 10\\
R -- 470 Ohm -- Pin 04\\
G -- 470 Ohm -- Pin 05\\
B -- 470 Ohm -- Pin 06\\
