USB and FireWire (IEEE1394) are recommended and widely used computer connections. Both USB and FireWire connections are currently considered fast and inexpensive industry standards and found on many cameras and monitors.
\r\nAnalog (composite or component) allows you to connect your microscope to analog video cameras, directly to a video conferencing system or VCR.
\r\nRS-232 standard refers to serial cable connectors on microscopes used to connect to computers and visual displays; this is an older computer standard then USB or FireWire.
\r\nS-Video (Separate Video) is a physical video interface signal much the same as the composite video. S-Video signals are considered of a better quality than composite video; because the signal carries the luminance and chrominance information separately.\r\n
