circuit the Input switches its state to "closed". The Input changes its state into "open" if no current
detected in the electric circuit.
NO (normally open)
NC (normally closed)

Output is a pair of contacts (normally-open and normally-closed) and common wire connected to
a relay. The relay may stay either on "active" or in "inactive" state. Active state means that the
current passes through the relay coil and the common contact is connected to the normally-open
contact. Inactive state means that no current passes through relay coil and the common contact
is connected to the normally-closed one.
Figure 3-11. Schematic of the outputs
The IO status is transmitted over an IP-based channel either by UDP or by TCP messages. Point-
to-Point and Point-to-Multipoint network scenarios are supported.
Detailed configuration examples can be found in the GigaFlex Configuration Manual.
3.3.5 LCT USB Connector
The Local Craft Terminal (LCT) Type Mini-B USB connector allows local access to the command
line interface of the GigaFlex models. If connected to a PC, a new serial port will be available for
communication with the device. Start your favorite terminal emulation program and select new
serial interface to initiate configuration session.
3.3.6 SD Card and USB Host
A Micro SD card and USB flash stick can be used for saving and restoring configuration and
firmware. Check the configuration manual for details.
3.3.7 Factory Default Button, Default IP Address
It is possible to restore the default configuration of a unit if the Factory Default (FD) button will be
pressed and held for 15 seconds during boot process. The IP address will be overwritten to the
default IP address 192.168.0.235.
NOTE:
The FD Button erases startup configuration, so the factory default values will be
loaded. Please note that FD button does
’t restore t e i itial firmware.
