q Operate Indicator (OPERATE)
Is on when the power of the WJ-SX850 Matrix Switcher
Card Cage is turned on.
Note: The power switch of this cage is located under-
neath the front panel.
Remove the front panel by removing two screws on
the panel.
w VS/VD Input Connector (VS/VD IN)
Accepts either the VD (Vertical Drive) pulse or the VS
(Video Sync) signal for synchronizing the system.
Notes:
• This input is looped through to the VS/VD Output
Connector.
• When the VD (or VS) signal is supplied to the VS/VD
Input Connector, turn the VS/VD selection switch
(SW7) on the circuit board to the VD (or VS) posi-
tion. The factory default setting of the VS/VD selec-
tion switch (SW7) is VD. Ask qualified service per-
sonnel about setting up this switch.
• The external sync signal should meet EIA RS-170
specifications and should not contain any jitters,
such as a VCR playback signal.
e VS/VD Output Connector (VS/VD OUT)
Outputs either the VD (Vertical Drive) pulse or the VS
(Video Sync) signal for synchronizing other system
components.
Note: The input at the VS/VD Input Connector is looped
through to this output. These inputs and outputs are
connected internally.
r VD Output Connector (VD OUT)
Outputs VD (Vertical Drive) pulses for synchronizing
other system components.
Notes:
• The internal VD pulse or the looped-through exter-
nal VD pulse is provided at this connector.
• When the VS signal is supplied to the VS/VD Input
Connector, the VD output signal from the VD Output
Connector will be delayed by approximately 15 µs
with respect to the V-sync of the VS input signal.
