CD VS/VD Input Connector (VSA^D IN)
Accepts either the VD (Vertical Drive) pulse or the
VS (Video Sync) signal for synchronizing the sys
tem.
Notes:
• This input is looped through to the VSA/D Output
Connector.
• When the VD (or VS) signal is supplied to the
VSA/D Input Connector, turn the VS/VD selection
switch (SW7) on the circuit board to the VD (or
VS) position. The factory default setting of the
VS/VD selection switch (SW7) is VD. Ask quali
fied service personnel 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.

(3) VS/VD Output Connector (VS/VD OUT)
Outputs either the VD (Vertical Drive) pulse or the
VS (Video Sync) signal for synchronizing other sys
tem components.
Note: The input at the VS/VD Input Connector is
looped through to this output. These inputs and
outputs are connected internally.
(4) VD Output Connector (VD OUT)
Outputs VD (Vertical Drive) pulses for synchronizing
other system components.
Notes:
• The internal VD pulse or the looped-through
external 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 ps with respect to the V-sync
of the VS input signal.
