[EXT.TERM-ON/OFF] Terminal On/Off
14
Switch of External Synchronization
Signal
This is a terminating ON/OFF switch for
the external synchronization input signal.
When this is switched ON, termination is
executed via a 75 resistor.
ON: terminates at 75 .
OFF: does not terminate at 75 .
(ON: At time of factory shipment)
[INT/GL, LL] Selector Switch for
15
Synchronizing System
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 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)
(INT/GL: At time of factory shipment)
[DUPLEX, SIMPLEX] Selector Switch
16
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).
E-10
SIMPLEX:
This switch sets to SIMPLEX when the
transmission between the camera and a
remote control unit is in a simplex system
(one-way).
(DUPLEX: At time of factory shipment)
[RX.TERM-ON/OFF] RX Signal Terminal
17
ON/OFF Switch
This sets whether or not the signal
between RX + and RX – on the back
should be terminated at the value of
110 resistance.
ON: Terminated.
OFF: Not terminated.
If the system including the camera is the
M.DROP (Multi-drop, RS-485) system,
only the last camera mounted along the
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. (
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

[AUX, GND] Auxiliary Input/Output Terminals
21
If there is any change in the area set on the
MOTION DETECT screen, these terminals
output the corresponding signals. (
These terminals also output the B&W/
COLOUR signal. (
[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. (
[B&W: make; COLOUR: break]

25
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
Page 30) connector, the camera operation is
automatically synchronized with the
external sync signal.
To terminate this connector at 75 , turn
ON the EXT.TERM switch
