1.  

AC/IN

Input for power cord connected to electrical 
outlet. 

2.  

Y/C IMPEDANCE Switch

The Y/C IMPEDANCE switch selects
the S-VIDEO impedance.

Set the switch to the 75

position

when only one monitor is used, or
when the monitor is used as the last
monitor in a chain.

Set to HIGH when another monitor is
connected to the Y/C OUT connector
for loop-through operation.

3.  

Y/C Connector

There are two MINI DIN type
connectors for the Y/C IN (Input)
/OUT (output) for looping through 
to other video monitors.

Y/C PIN DESCRIPTION: 
S-VIDEO (Separated Y/C signal IN/OUT)

4.  

AUDIO Connector

There are two RCA phone type connectors for the
AUDIO IN (Input) / OUT (output) for looping
through to other video monitors.

NOTE

: The AUDIO IN/OUT is not dependent

upon the VIDEO input.

5.  

VIDEO A/B (IN/OUT) Connector

There are four BNC connectors for the composite
VIDEO A/B inputs and outputs.

NOTE

: The impedance is automatically set to 75

by the input of a signal on the input connector
while operating in a single connection mode.
However, if a cable is connected to the output
connector, the connection is placed into the open
status by the multiple connection and high 
impedance automatically selected.

CAUTION

: Do not leave an unused cable

connected to the monitor. If a single cable is used, 
it must be connected to the input connector for the 
75

auto-termination selector to function properly.

MAINTENANCE

Preventive maintenance allows detection and
correction of minor faults before they become serious
enough to cause equipment failure.

Every three months, perform the following

:

1. Inspect all cabling for deterioration or other damage.

2. Clean the components with a damp, clean cloth.

3. Verify that all mounting hardware is secure.
