3.3 Connections

Single monitor
See FIGURE 2 for 9in. & 12in. monitors, see
FIGURE 5 for 17in. monitor, and see FIGURE 8 for
20in. monitor.
Looped-through monitors
Up to three monitors can be connected in series by
using the VIDEO IN and VIDEO OUT connectors
(see FIGURES 3, 6 & 9).
While operating in single connection mode,
impedance is automatically set to 75Ω by the input of
a signal on the input connector. However, if a cable is
connected to the output connector, the connection is
placed into open status by the multiple connection,
and high impedance is automatically selected.
NOTE: Do not leave an unused cable connected to the
monitor. If a single cable is used, it must be connected
to the input connector so the 75Ω auto-termination
selector functions properly.
