DI/DO functionality can be set to either Normal Open or Normal Closed type as follows.
• Normal Open Type: Normal is OPEN, and goes CLOSED when triggered by an event.
• Normal Close Type: Normal is CLOSED, and goes OPEN when triggered by an event.
5.4.1. DI/DO for FW-3450/5450/5470
There are 4 serial Input ports and 4 output ports in FW-3450 and FW-5450. A good example of the
Input and Output usage is, an external sensor can be connected to the Input port, and a warning
light is triggered by the Output port.
DI/DO Setup
Each Input and Output port can be assigned unique name respectively, so that you can easily
distinguish every Input and Output ports from others by those names. This can be very useful in case
of managing multiple sites with separate Costar Video Servers, where you can quickly and correctly
identify which Sensor Input is detected or determines which Alarm Output needs to be activated.
You can define Sensor Input Name and Alarm Output Name as you want, which should be up to
31 alphanumeric or up to 15 Unicode characters.
DI/DO Control
These models have 4 output ports and they act like a push button. When you click On button, it
works like the push button pressed. When you click Off button, it works like the push button is
released.
With DI (Sensor Input) Status, you can find out the status of the Alarm Input port. If the
checkbox of Check (On) is displayed as checked, that means the alarm is activated. If not checked,
that means no alarm is activated.
Note: Make sure the type of the sensor and use it correctly to the type. If a Sensor Input
is not used, it must be set to Normal Open Type to avoid a false input.
