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

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,

	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).

	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)
18	NOT USED
	This cannot be used. Do not switch.

19	[DC 12V, AC 24V] Power input terminals
	(TK-C1480U and TK-C1480E)
	To input DC 12V or AC 24V power.
20	[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.

21	[AUX, GND] Auxiliary OutputTerminals
	If any change occurs in the area that was
	set on the MOTION DETECT screen, these
	terminals output signals. ( Page 31)
	[Open-collector Low signal. Maximum
	voltage 30V, Current 30mA.]
22	[Y/C OUT] Y/C output connector
	This 4-pin connector outputs the luminance
	and chrominance signal.

23	[VIDEO OUT] Video signal output
	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 75Ω, turn
	ON the EXT.TERM switch 14 .
