This switch sets the synchronizing system

 

for the camera.

 

INT/GL:

 

This is set for internal synchronization

 

(INT) or external synchronization (GL).

 

LL (Line Lock):

 

The camera’s vertical synchronization is

 

locked to the AC 24V power line frequency.

 

When switching between multiple

 

cameras using a switcher, selecting this

 

mode and adjusting the vertical phase

 

can reduce the monitor sync disturbances

 

occur that when the camera image is

 

switched. (This cannot be used in regions

 

where the power frequency is 60 Hz)

[DUPLEX, SIMPLEX] Selector Switch

 

for Transmission System

 

If the setting is changed, be absolutely

 

sure to switch on the power again.

 

DUPLEX:

 

This switch sets to DUPLEX when the

 

transmission between the camera and a

 

remote control unit is in a duplex system

 

(two-way).

control signal cable is set to “ON” and the other cameras are set to “OFF”. In case of the M.DROP system, it becomes necessary to set the Machine ID. ( Page 35) If the system including the camera is the P TO P (Point to Point, RS-422A) system, set this switch of all the cameras to “ON”. The item STYLE on the COMMUNICA- TION screen sets M.DROP or P TO P ( Page 35) (ON: At time of factory shipment)

NOT USED This cannot be used. Do not switch.

[TX+A, TX-B, RX+C, RX-D] Control

 

signal connection terminals

 

Terminals for inputting signals with

 

electrical characteristics conforming to

 

the EIA/TIA RS-422A or RS-485 standard.

[AUX, GND] Auxiliary Input/Output

 

Terminals

 

If there is any change in the area set on

 

the MOTION DETECT screen, these

 

terminals output the corresponding

 

signals. ( Page 34)

 

These terminals also output the B&W/

 

COLOUR signal. ( Page 30)

 

[Open-collector low signal. Maximum

 

voltage 30V, current 30mA.]

 

When carrying out B&W/COLOUR

 

switching using the control signal, the

 

signals are input through these terminals.

connector

 

This BNC connector outputs a composite

 

video signal. Connect this to the video input

 

connector of a video monitor, switcher, etc.

24

[POWER] Power indicator lamp

 

This lamp lights when power is supplied

 

to the camera.

25

[SYNC IN] Sync signal input connector

 

This BNC connector accepts the input of

 

an external sync signal such as a composite

 

video (VBS) or black burst (BB) signal.

 

When a sync signal is input into this

 

connector, the camera operation is

 

automatically synchronized with the

 

external sync signal.

 

To terminate this connector at 75, turn

 

ON the EXT.TERM switch 14 .
