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).

[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.

Computer

Alarm input terminal

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.
