Audio In/Out
– Out : Connect an amplifier to this port (line out).
This device does not feature a built-in audio
amplifier unit and therefore requires the user to
purchase a separate speaker system with a built-in
amplifier.
– In : Connect an audio source to this port. (line in)
•
Alarm In/Out
–
Out
: It is the BJT (Bipolar Junction Transistor) -
open collector output. If the voltage and current
exceed the specification limit (Max load: 50mA,
Max Voltage: 30VDC), the product could be
damaged. When connecting the device which
exceeds the specification limit, refer to the picture
(circuit) below.
If used with an external inductive load(e.g. relay),
a diode must be connected in parallerl with the
load for protection. Otherwise, the product could
be damaged.
–
In
: Connect an alarm-in device to this port.
(Mechanism: Choose between an NC (Normally
Closed) type or an NO (Normally Open) type)
→
Connect a mechanical or electrical switch to the
alarm in port and the GND (ground) connector.
Alarm in range is 0V to 5V. In order to detect alarm
input from an electrical switch, the signal must be
higher than 4.3V from an NC switch or less than
0.3V from an NO switch and must last for longer
than 0.5 seconds.
The table below shows the network cable specifications.
