PC Input (HD15): Connect a PC’s VGA output to this port. Set the
HD/PC slide switch on bottom right corner to Right (PC) to enable this
input
PC Bypass (HD15): Connect a local VGA monitor to this loop-thru
output if needed (can be left unconnected)
HD Input (3 RCA): Connect a DVD, Satellite Receiver, or Set-top
Box HD component video output to this port. Set the HD/PC slide
switch on bottom right corner to Left (HD) to enable this input
HD Bypass (3 RCA): Connect a local HDTV to this loop-thru output
if needed (can be left unconnected)
S-V Output: This is the down converted S-Video output. This
connector and the composite video outputs are active at the same time
and you can use both if you with. However, the HD output and the
CV/SV outputs are mutually exclusive. This means that you have to
select the type of output that you want via the IR remote (Press the
“Output” key on the remote), or Serial port using the PC software.
C-V Output: This is the down converted Composite Video output.
This connector and the S-Video outputs are active at the same time and
you can use both if you with. However, the HD output and the CV/SV
outputs are mutually exclusive. This means that you have to select the
type of output that you want via the IR remote (Press the “Output” key
on the remote), or Serial port using the PC software.
YCbCr Output: This is the down converted Component Video output.
It is sometimes referred to as YPbPr. However, this output and the
CV/SV outputs are mutually exclusive. This means that you have to
select the type of output that you want via the IR remote (Press the
“Output” key on the remote), or Serial port using the PC software.
This output is available for pass-through when the Video Scaler is in
the PC Input (Bypass) mode or if unit is turned off.
RS-232: This is the serial control port. You can use the PC software to
control it from a PC, or write your own control software and control
the unit from any serial control device. Only RX and TX pins are used.
DC Power Input: Only connect regulated 5v DC to this 2.1mm input.
If you connect any other voltage it will damage the unit.
