Video Relay Bypass
The mechanical video relay bypass option (VRB-HD-001) may be fitted
which routes the main HD-SDI input source through the system in the event
of a power failure.
BNC no. Signal Name
IN HD-SDI Input
>A To A input
>PGM From PGM output
OUT HD-SDI Output
The board should be placed in the
spare slot next to the output card as it derives
its power from this card.
Connection of Analogue Faders
Analogue faders may be used to control a main fade, a fade to black and the
levels of transparency, gain and clip. A resistive linear potentiometer (a
"pot") of at least 10KΩ should have its fixed terminals connected between
pin 7 (+5V) and pin 15 (Ground). The variable output of the pot should
connect to the appropriate fader input pin.
Screened cable should be used to connect the fader to the Imagestore HDTV.
The screen of the cable should be connected to ground only
at the Imagestore
HDTV end of the cable to avoid "earth loops" and restrict extraneous signal
levels to less than 1 mV.
