APPENDIX #2 – PIN CONFIGURATION

PIN	FUNCTION	DESCRIPTION
1	RS232-TX	DVR can be controlled remotely by the keyboard of PC by using RS-232 serial
		communication signals.
2	RS232-RX	DVR can be controlled remotely by the keyboard of PC by using RS-232 serial
		communication signals.
3~6	ALARM INPUT	To connect the wire from ALARM INPUT ( PIN 3 -- 6 ) to GND ( PIN 9 )
		connector, DVR will start recording and the buzzer will be on.
		When “MENU -> CAMERA -> ALARM” is set to “Low” : When the alarm input
		signal is “ Low ”, the unit starts to record and buzzer.
		When “MENU -> CAMERA -> ALARM” is set to “High” : When the alarm input
		signal is “ High ”, the unit starts to record and buzzer.
7	EXTERNAL	Under the normal operation, COM connects with NC and disconnects from NO.
	ALARM NC	But when any alarm is triggered, COM disconnects with NC and connects with
		NO.
		Attention: The voltage restriction is under AV/DC 30V.
8	EXTERNAL	Under the normal operation, COM disconnects with NO. But when any alarm is
	ALARM NO.	triggered, COM connects with NO.
		Attention: The voltage restriction is under AV/DC 30V.
9	GND	Signal GND.
10	RS485-B	DVR can be controlled remotely by the keyboard of PC by using RS-485 serial
		communication signals.
11	RS485-A	DVR can be controlled remotely by the keyboard of PC by using RS-485 serial
		communication signals.
12~13	PIN OFF
14	ALARM RESET	Connecting the wire from ALARM RESET (PIN 14) to GND (PIN 9) connector
		will disable alarms. An external signal to ALARM RESET (PIN 14) can be used
		to reset both ALARM OUTPUT signal and DVR’s internal buzzer. When any
		alarm has been triggered, the signal becomes “Low”, and all alarm activities will
		be stopped. Under the normal operation, the signal remains “High”.
15	EXTERNAL	Under the normal operation, COM disconnects with NO. But when any alarm is
	ALARM COM	triggered, COM connects with NO.
		Attention: The voltage restriction is under AV/DC 30V.

PIN Connection Application

When the magnetic contact is opened, the alarm will be triggered and the recording is on. At the same time, COM connects with NO and the siren with strobe starts wailing and flashing.

NOTE: Please go to MENU -> ADVANCE -> DETECTION -> DETECTION SETUP, and set ALARM to LOW on the local machine.
