14[EXT.TERM-ON/OFF] Terminal On/Off 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 Ω resistor.

ON: terminates at 75Ω.

OFF: does not terminate at 75Ω.

(ON: At time of factory shipment)

15[INT/GL, LL] Selector Switch for Synchronizing System

This switch can set a synchronizing system of 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 occurring when the camera image is switched. (This cannot be used in regions where the power frequency is 60 Hz (50 Hz ( ):TK-C1480U) (INT/GL: At time of factory shipment)

16[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).

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)

17[RX.TERM-ON/OFF] RX SignalTerminal ON/OFF Switch

This sets whether or not the signal between RX + and RX – on the back 20

should be terminated at the value of 110Ω resistance.

ON: terminates.

OFF: does not terminate.

If the system including the camera is the M.DROP (Multi-drop, RS-485) system, only the camera mounted at the terminal of control signal cable is set to “ON” and the other camera is set to “OFF”. In case of the M.DROP system, it becomes necessary to set the Machine ID. ( Page 33)

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 33)

(ON: At time of factory shipment)
