9 / 13 page Test Circuits (Continued) Pin Descriptions Pin No. Pin Name Schematic Description 1 2 3 Red OSD Input Green OSD Input Blue OSD Input These inputs accept standard TTL inputs. Each color is either fully on (logic high) or fully off (logic low). Connect unused pins to ground with a 47k resistor. 4 Video/OSD Switch This input accepts a standard TTL input. H = OSD L = Video Connect to ground with a 47k resistor when not using OSD. DS012684-12 *Note: All video inputs must have a series 33 Ω resistor for protection against EOS (Electrical Over Stress). If the OSD input signals are external to the monitor, or these signals are present any time when +12V is not fully powered up, then the OSD inputs also require a series 33 Ω resistor. FIGURE 7.
