V (vertical) sync signals in addition to the RGB outputs. This results in a total of five signals (RGB/HV). For many configurations, these five signals will be part of a single VGAVGA output cable and there will be no need to worry about the individual signals. For some devices you may need to connect all five of these signals to individual BNC or possibly RCA type connectors. See Table 1 below for more specific connection info.
Some display devices require that the two H and V sync signals be combined into a single “composite sync” signal, resulting in a total of 4 signals (RGB/S). Devices requiring composite sync typically accept the three video signals as well as the composite sync signal on BNC type connectors.
Other devices require that the composite sync signal be further combined with the RGB Green signal. This is referred to as “sync on green” and is typically connected to the device using 3 BNC connectors, though 3 RCAs may also be used.
If your output device falls into either of these last two categories – composite sync or sync on green – the iScan Plus v2 will need to be internally configured to output the appropriate type of sync signal. To do this you will need to follow the directions in Appendix A.
