Global Caché Flex Link Relay & Sensor Cable (GCFLCRS) — Quick Start Guide

Quick start guide for the Global Caché Flex Link Relay & Sensor Cable — an accessory cable for the iTach Flex series that adds relay outputs and sensor inputs, configurable through a browser-based interface.

Getting Started

Once the iTach Flex is connected to the network (see the iTach Flex Quick Start guide), plug the Flex Link Relay & Sensor cable into the Flex Link Port.

To configure the Relay & Sensor cable: right-click on the unit's entry in iHelp and select Configure. Alternatively, access the setup pages manually by typing the unit's IP address into a web browser.

To access the Relay & Sensor cable settings, select Flex Link Cable, then Relay/Sensor. The page updates to display the current saved configuration, or default settings if the cable hasn't been configured yet. The webpage provides a basic configuration and control interface to demonstrate and test relay and sensor functionality.

Relay Outputs

Relay outputs can be configured as various relay types for controlling a wide range of devices. To configure a relay:

1. Select the desired mode using the Relay Type dropdown menu on the webpage
2. Install the hardware jumpers as indicated by the webpage's conceptual diagram for the selected relay type
3. Press Save Changes to apply the new settings
4. Connect your device to the connector terminals as indicated

Relay outputs can then be controlled using the Current State toggle buttons and pressing Save Changes. Note that relay output states are not automatically updated if changed by a different client — press Refresh to update the displayed current output states.

Sensor Inputs

Sensor inputs can be configured to sense the presence of AC or DC voltage/current, or dry contact closure. Each sensor input uses a pair of pins on the terminal block connectors.

• Voltage sense mode: set jumpers at the positions nearest the connector terminals, then connect the voltage/current source to the pair of adjacent pins (e.g. pins 1–2)
• Contact closure mode: set jumpers at the positions farthest from the connector terminals, then connect the contact closure switch to the two adjacent corresponding pins (e.g. pins 3–4)

The state of the sensor inputs is shown by the Input States toggle indicators, located just below the Relay outputs section.
