1 AC power connector — Standard AC power connector attaches
the scaler to any power source from 100VAC to 240VAC, operating
at 50 Hz or 60 Hz.
2 Input connectors — BNC female connectors for RGsB (sync on
green), RGBS (composite sync), or RGBHV input. One set of
connectors is used for the input device, and one set is available for
a local monitor, if desired.
You must set the 75
Ω
/Hi-Z switch to correspond to the presence or
absence of a local monitor. See item 3 below.
3 75
Ω Ω Ω Ω Ω
/Hi-Z switch — Provides termination for computer video
input. Set the switch to 75
Ω Ω Ω Ω Ω
if no local monitor is attached to the
scaler, and install two BNC 75-ohm termination adapters, one on
the H/HV input BNC connector, and one on the V input BNC
connector, of the unused set of input BNC connectors. Set the
switch to Hi-Z if a local monitor is attached.
4 Output connectors — BNC female connectors for RGsB (sync on
green), RGBS (composite sync), or RGBHV output.
5 Sync selection switch — Allows you to choose how the sync
output signals will be routed:
H — If the switch is set to H, the scaler outputs separate
horizontal and vertical sync signals; only horizontal sync is
routed through the H/HV output connector.
HV — If the switch is set to H/V, the scaler outputs a composite
sync signal (H and V combined) on the H/HV output
connector.
SOG — If the switch is set to SOG (sync on green), the scaler
outputs a composite sync signal on the green video signal
via the G output connector.
6 VGA output connector — 15-pin HD female VGA connector for
the output projector.
You can connect only one output device. Do not connect two
output devices, or the scaler will be double-terminated.
7 RS-232 connector — 9-pin D female connector that allows you to
attach a computer or controlling device for remote control of the
DDS 100.
