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”: W hen the alarm input
signal is “ Low ”, the unit starts to record and buzzer.
When “MENU -> CAMERA -> ALARM” is set to “High” : W hen the alarm input
signal is “ High ”, the unit starts to record and buzzer.
7EXTERNAL
ALARM NC Under the normal operation, COM connects with NC and disconnects from NO.
But when any alarm is triggered, COM disconnects with NC and connects with
NO.
Attention: The voltage restriction is under AV/DC 30V.
8EXTERNAL
ALARM NO. Under the normal operation, COM disconnects with NO. But when any alarm is
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
ALARM COM Under the normal operation, COM disconnects with NO. But when any alarm is
triggered, COM connects with NO.
Attention: The voltage restriction is under AV/DC 30V.
16~17 GND Earth GND
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.
