1 - 3. Red, Green, Blue Inputs:
Connect the RED, GREEN, BLUE signals from the external video
multipliers to this jack.
4. H/C Sync Input:
When COMPOSITE SYNC is available, connect the feed from the external video
multipliers to this terminal. If separate horizontal and vertical synch are present, connect the
HORIZONTAL SYNC feed to this jack.
5. Vertical Sync Input:
If separate sync feeds are being used, connect the VERTICAL SYNC feed to
this jack.
6. AC Power Input:
Connect the supplied AC power cord to this receptacle.
7. The POWER LED
is a multi-purpose indicator:
When the LED is dark the AC power to the unit is turned off.
When the LED is flashing on and off, power is connected to the unit, this indicates that the unit is
in the standby mode.
When the LED is on the unit is powered on.
NOTE: Depending on the configuration of the “Auto Power” the unit may be in a “Stand By”
mode, awaiting signal information. ALWAYS REMOVE THE AC POWER CORD TO POSITIVELY
TURN THE UNIT OFF BEFORE MAKING ANY INTERNAL ADJUSTMENTS.
8. IR Sensor:
This window is the sensor for the HD-700’s remote control system. For best operation,
make certain that the sensor has a direct view of the screen so that remote commands made by pointing
the control at the screen will be bounced back to the sensor. If the sensor window is obstructed a
remote IR extension system should be used.
9. RS232C Port:
This DB-9 plug is used to operate the HD-700 directly from a compatible central
controller.
NOTE:
THIS IS A DATA PORT ONLY. DO NOT MAKE ANY VIDEO SIGNAL CONNECTIONS TO THIS INPUT!
10. RY1 and RY2:
These are two pairs of relay contacts for triggering an electric screen. RY1 is
assigned to Power On/Off. RY2 may be assigned to any one of sixty scan memories in the Video
Memory Set Up.
