Global Cache FLC-RS Flex Link Relay and Sensor Cable
Getting Started
Once the Flex is connected to the network (see Flex Quick Starts), plug the
Flex Link Relay & Sensor cable (FLC-RS) into the Flex Link Port.
To configure the FLC-RS, right-click on the unit entry in iHelp and select
Configure, or enter the Flex unit’s IP address into a web browser to access
the Flex Configuration page.
To access the settings, select the Flex Link Cable tab. Then select Relay &
Sensor from the Change Flex Link cable field. The page will update and display
the current saved configuration or default settings if the cable is not yet
configured.
The setup webpage provides the basic configuration and control interface to
demonstrate and test relay and sensor functionality.
Relay Outputs
The four Relay outputs on the left side of the cable can be configured as a variety of relay types for controlling a wide range of devices. To configure a relay, select the desired mode on the webpage using the Relay Type dropdown menus. Then install the hardware jumpers as indicated in the diagram and press Save Changes. Connect your device to the connector terminals as indicated (the webpage displays a conceptual diagram of the selected relay type). The relay outputs can now be controlled by using the Current State.
Voltage Sense Mode
Set jumpers at the positions nearest the connector terminals, then connect
the voltage/current source to the pair of adjacent pins (pins 1-2 in the
example above).
Contact Closure Mode
Set jumpers in the positions farthest away from the connector terminals, then
connect the contact closure switch at the two adjacent corresponding pins
(pins 3-4 in the example above).
When Relay & Sensor mode is enabled, the sensor can be polled through the TCP
API or HTTP/RESTful API for each sensor’s state.
The Flex also supports iTach Sensor and iTach Sensor Notify compatibility
modes for iTach IP2IR sensor drivers, which allow drivers designed for iTach
to work with the Flex Sensor module.
These can be selected under Mode and be applied by clicking Save Changes.
