Switch and LED
The 4 switch’s (SW-1 to SW-4) is used to test the relay functions. The LED’s
are also used to indicate any fault modes that the software can end in (see
section: fault finding).
When powering the system by USB it is not possible to test the relays.
To get the unit into boot mode (used then using programming over RS-232),
the following needs to be done:
Press, and hold all 4 switch for 5 seconds (until all 4 LED flashes fast)
I/O Ports
The Neets Control – ZULU has 24 i/o’s onboard. They can be used for external
keyboard, PIR (movement) sensor, Keyboard lock, extra relays and so on.
The ports are not potential free, that means you will need external relays if
you need to prevent e.g. ground loops.
When used as output they are active low (when the software says activated
the pin are tired to GND thru a FET transistor also called open drain/collector
function). You can draw up to 24VDC/500mA
When used as input the voltage has to be below 1 Volt DC to be accepted as
LOW, and above 4 VDC (but below 24 VDC) to be accepted as high.
LAN
The network connector is for connecting the system to the local area network.
There are two LED’s on the connector.They have the following meaning:
Color:
Off
On
Blink
Yellow
No Link
