PRELIMINARY
Video Signal Routing
The input’s signal format (RGB, S-video, or composite video) determines where the
signal is output.
Composite video signals are always output on the Video BNC connector.
S-video signals (MLS 406 Series only) are always output on the Y and C (luma and
chroma) BNC output connectors.
RGB/computer-video input signals are sent to the RGB output BNC connectors,
but only if the input is configured as an RGB input.
See pages 2-4 through 2-6 for information on cabling. See pages 4-4 through 4-11
for information on video configuration.
Monitor Output modes
Which signal, if any, is output via the Monitor Output connector depends on the
selected input’s signal type and on the Monitor Output mode. Monitor Output
modes are selectable only via RS-232 control (see chapter 4, Serial Communication).
• Mode changes affect only how the Monitor Output is determined.
• Changing the mode does not affect the other outputs in any way.
Standard mode (mode 3)
• If the selected input is S-video or composite video, there is no Monitor Output.
• If the selected input is RGB, that input’s signal routed to the Monitor Output.
DA (distribution amplifier) mode (mode 2)
• If any configurable input (3 or 4 on the MLS 304MA and MLS 304SA;
4, 5, or 6 on the MLS 406, MLS 406MA, and MLS 406SA) is S-video or
composite video, there is no Monitor Output.
• If all the configurable inputs are set for RGB, the input 4 signal on the
MLS 304MA/MLS 304SA or the input 6 signal on the MLS 406/MLS 406MA/
MLS 406SA becomes the Monitor Output, no matter which input is selected.
RGB follow mode (mode 1)
• If all the configurable inputs (3 and 4 on the MLS 304MA and MLS 304SA;
4, 5, and 6 on the MLS 406, MLS 406MA, and MLS 406SA) are RGB, and
• the selected input is MLS 304MA/MLS 304SA input 1 or 2; or MLS 406/
MLS 406MA/MLS 406SA input 1, 2, or 3; the highest numbered (4 or 6,
depending on the model) RGB input’s signal is sent to the Monitor Output.
• the selected input is RGB, that signal will be sent to the Monitor Output.
• If the selected input is configurable and any configurable input is set for S-video/
composite video, there is no Monitor Output.
The table on the next page summarizes the modes.
