Front USB Configuration
The USB port is used exclusively for configuring the LiMa from the Neets
Project Designer software. It can't be used to control any external devices.
The LiMa must be powered by PoE supply that complies with IEEE
802.3af and 802.3at, type 1 in order to configure it by USB.
The USB connector for connecting to the LiMa is "mini USB B 5P". You
can buy this cable on the web (select a USB A to Mini USB B 5P).
RS-232 Status Indication
The RS-232 status LED displays the current status of the RS-232 ports.
The LEDs illuminate when there is active communication on the port.
IO Status Indication
The IO status LED displays current status of the I/Os.
When an IO is configured as input, the yellow LED marked "in" will
illuminate when the input is high and turn off when the input is low.
The green LED marked "out" will remain off.
When an IO is configured as output, the green LED marked "out" will
illuminate when the output is high and turn off when the output is low.
The yellow LED marked "in" will remain off.
