TURNING ON THE MACHINE
NOTES
1) The machine should only be turned on after all connections are
completed and all source devices have been turned on. Do not
attempt to connect or disconnect any video signal to the
machine while it is turned on.
2) The socket-outlet should be near the equipment and should be
easily accessible. To fully disconnect equipment, remove the
power supply adapter from the mains socket.
9.1 Operation of the SDI to Analog Converter
Connect the SDI source to the "SDI IN" socket.
Connect the video acceptor/s to the appropriate output socket/s. The
SD-7401
allows the simultaneous
use of all outputs - RGB or YUV (Component video), Y/C (s-Video), and CV (Composite video).
Configure the DIP-switches at the back of the machine accordingly, as described below.
Operate the sources, the
SD-7401
and the acceptors.

Switch # 1
-
Selects whether the
SD-7401
outputs an analog form of the SDI input, or whether the
machine generates a 75% color bar. Note that the bar generator requires an SDI input in order to
operate correctly.
Switch # 2 - Selects whether a pedestal (7.5 IRE setup) is to be used for NTSC.
Switch # 3 - Selects the power-on configuration of the Component video output, i.e. RGB or YUV
(Y, B-Y, R-Y).
Switch # 4 - Selects the line standard. This switch must be set according to the line standard of the
SDI input.
10 TAKING CARE OF YOUR MACHINE
Do not locate your machine in an environment where it is susceptible to dust or moisture. Both of
these may damage the electronics, and cause erratic operation or failure. Do not locate your machine
where temperature and humidity may be excessive. Doing so may also damage the electronics, and cause
erratic operation or failure of your machine. Do not clean your machine with abrasives or strong cleaners.
Doing so may remove or damage the finish, or may allow moisture to build up. Take care not to allow
dust or particles to build up inside unused or open connectors.
11 TROUBLESHOOTING
NOTES
1. Please note that if the output signal is disturbed or interrupted by very strong external
electromagnetic interference, it should return and stabilize when such interference ends. If not, disconnect
power from the machine and reconnect again to reset the machine.
