CONNECTIONS

Power Cable

1. Keep the power of this monitor to the OFF position
during connection.

2. Connect the Power Cord to a 60F!z grounded elec

trical outlet 120V AC.

Video Cable
Note:

• Always set the last monitor’s Video Termination
Switch to 75 ii, and set the Video Termination
Switch of Intermediate monitors to Fii-Z.

Camera Coax.

Use the RG-59/U (3C-2V), RG-6/U (5C-2V), RG-

11/U (7C-2V) or RG-15/U (10C-2V) coaxial cable.
Up to 10 monitors can be hooked up in this config
uration before signal loss occurs. Total cable
length should not exceed 150m (500 feet)

2. Wiring Precautions :

• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times its diameter.

• Never staple the cable - not even with circular sta
ples,

• Never crush or pinch the cable.
All these will change the impedance of the cable
and cause poor picture quality.

External Sync

When a non-composite video signal is connected to
the monitor, it will be necessary to connect an external
composite sync signal to the monitor.

1. Connect the Sync Input Connector (17) on the

video monitor to the sync signal source by means
of a 75 Q coaxial cable.
Set the Sync Selector Switch (16) to the EXT posi
tion.

SYSTEM CONNECTIONS

2. Muitipie Monitor Connection

1. Single Monitor Connection

• Connect the Video Input Connector (11) on this
monitor to the Video Output Connector of the cam
era with 75-ohm coaxial cable.

• Set the Video Termination Switch (13) to the
75ii position.

• Set the Sync Selector Switch (16) to the I NT posi
tion.

First Video Monitor

Conneci the Video Input Connector (11) on this
monitor to the Video Output Connector of the cam
era with 75-ohm coaxial cable.

Connect the Video Output Connector (12) on the
first monitor to the Video Input Connector (11) on

the second monitor with 75-ohm coaxial cable.
Continue until all monitors are connected.
Set the Video Termination Switch (13) of the first

and intermediate monitors at Hi-Z position. Then

set the Video Termination Switch (13) of the last

monitor to 75ii position.

3. When used with External Sync

When a non-composite video signal is connected

to the video monitor, an external composite SYNC

signal must also be connected to the video moni

tor.

• Connect the Video Input Connector (11) on the
video monitor to the Video Output Connector of the

camera with 75-ohm coaxial cable.

• Connect the Video Output Connector (12) on the
first monitor to the Video Input Connector (11) on
the second monitor with 75-ohm coaxial cable.
Continue until the video signal is connected to all

monitors.

• Set the Video Termination Switch (13) of the first
and intermediate monitors to the Hi-Z position.

last monitor to the 750. position.

-8-

Set the Sync Selector Switch (16) to the EXT posi
tion.
Connect the Sync Input Connector (17) on the
video monitor to the sync signal source with' 75­ohm coaxial cable.

first monitor to the Sync Input Connector (17) on
the second monitor with 75-ohm coaxial cable.
Continue until the sync signal is connected to all
monitors.
Connect the Sync Output Connector (18) on the

last monitor to the Sync Input Connector on the
camera with 75-ohm coaxial cable.
Set the Sync Termination Switch (19) of the moni
tors to Hi-Z position. The sync signal is terminated
with 75-ohm in the camera.

Height Control
This recessed screwdriver control should be
adjusted simultaneously to give proper vertical
height consistent with good vertical linearity.
Adjustment should be made to extend the picture
limits approximately 1/10" beyond the top and bot
tom edges of the mask at over scanning operation.

Vertical Linearity Control
This recessed screwdriver control should be
adjusted to give good vertical linearity.

Underscanning Operation

7.
Set the Scan Size Switch (3) to the UNDER posi
tion to obtain the underscanning.

DC Restoration

DC restoration circuit provides a stable reference
for the black level. Set the switch to the ON posi
tion to prevent excessive contrast and preserve
shadow detail.
