IO Connectors
The LiMa has two I/O (Inputs/Outputs) which can be configured as either
output or input. Each I/O is available for connection to a PIR (movement)
sensor, keyboard lock, relays or for other compatible uses. The ports are
not potential free; you may need external relays to prevent ground loops
depending on your application.
When used as outputs, the I/O ports are active low. When activated, the
I/O ports are tied to GND through a FET transistor (also called open drain/
collector function). Each I/O can draw up to 24VDC/500mA.
When used as inputs, the applied voltage must be below 1 VDC to be
accepted as LOW, and above 4 VDC (but below 24 VDC) to be accepted
as HIGH. The inputs are default HIGH and must be connected to ground in
order to change state.
LAN Connector with PoE functionality
The LAN connector is used to connect the LiMa to the local area network.
The LiMa has Power over Ethernet functionality built into the LAN interface
connector.
You must connect the LiMa to your LAN if you are using any of the LAN
features of the product. The port features auto MDI-X which means that
you can connect the LAN port directly to other devices without the need
for a LAN switch.
The connector marked with PoE IN is used to power up the
entire control system. To power the LiMa, use a PoE enabled
switch which complies with IEEE802.3af. Or you can use the
PoE Injector (Part number 302-000508).
There are two LEDs on the connector with the following indication:
