CONNECTION
CONNECTIONS TO THE ALARM IN AND RS232C/RS485 TERMINALS
[A] RS485 (RJ-11) terminal connection
Make the connection to the RS485 control terminal using a
modular cable (sold separately).
•
If using a straight type cable, connect it between the A
terminals, or between the B terminals (see illustration below).
•
If using a crossed type cable, connect it from the A terminal
to the B terminal, or from the B terminal to the A terminal (see
illustration below).
[B] Using the push-lock terminals
Make the connections to pins A, B, C (earth) of the CONTROL
terminal using a twisted-pair cable (sold separately). Then,
connect signal A to A, and signal B to B.
[C] SENSOR ALARM OUT terminals
When the unit internal video sensor send a trigger, it will be
output at the SENSOR ALARM OUT terminals. By connecting
indicator lamps switching circuits to theses connectors (Fig. 1),
an indication can be generated when the video sensors send a
trigger.
For example, the video sensor alarm indicator lamps could be
laid out on a factory floor plan to give accurate indication of
trigger location. The terminals are normally open (NO). A trigger
at the video sensor for one of the cameras, will switch the signal
to LOW.
Connect a 9-pin D-SUB cable (sold
separately) from the RS232C terminal on the
rear panel to the computer serial connector.
