The following diagram depicts an incident response Relay Output scenario using a Normally Open
configuration for an automatic road barrier.
External device is triggered on the event of intrusion in a detection zone
Caution
Consideration and care needs to be given regarding how the security officers will reset,
command, and override incident responses. For example, if the system detects someone
walking in a detection zone and automatically executes a lockdown, security officers may
need a bypass for the lockdown.
Overview of RS232 and RS485 Connections
The RS262/485 connections made to the ioibox via its serial ports that can be split-out for two up
to two connections (RS232 and RS485 support). Dual connections split from one port to provide the
ability to connect two devices, such as a PTZ camera. Primarily used for connecting PTZ control
wires.
For more information on the pin-out, see the
section (page 64). The
RS232/RS485 connections can be utilized from custom programs that use the ioimage-API
(application program interface). For more information, refer to the ioimage-API User Guide.
Note
: An adapter cable RJ45 to 2 x RS232 DB9 + 1 RS485 lead wires can be purchased as
a separated accessory
Warning
: The RS232 standard specifies a maximum open-circuit voltage of +/-25 volts.
Exceeding this voltage can cause permanent damage to the unit.
Warning
: The RS485 standard specifies a maximum voltage of +12 V and -7 volts.
Exceeding this voltage can cause permanent damage to the unit.
