meshI/O

An iMesh-compatible add-on which facilitates the transmission of volt-free contacts over a wireless link.

Product Overview

meshI/O provides an easy way to connect multiple remote, digital devices where cabling is not readily available or ducting is prohibitvely expensive.

Typically used to connect upstream vehicle detectors to a junction signal controller, a single meshI/O unit will support up to 6 bi-directional digital inputs from inductive loops or other devices such as TrafiCam®, RADIX® magnetometers and Heimdall® detectors.    A second meshI/O unit installed at the controller end of the link converts the wireless transmission back to a digital output for presentation to a controller via screw terminals.  From the controller's perspective, the detector appears to be wired directly in.

Features and benefits

meshI/O is compatible with any detector which has relay or opto-isolated/switched outputs. It is fully bi-directional with a latency of just 3mS. In-built fault detection will automatically set a UTC controller's fault bit in the event of a dropped link.

meshI/O is available in two enclosure formats as shown in Figure 1 above:

An external-grade meshI/O unit built into an iMesh router powered by mains, dc or power-over-ethernet.

A cabinet-grade router where the meshI/O electronics is installed in a roadside cabinet.  In this arrangement the meshI/O unit can connect to either a cabinet-grade iMesh router installed alongside or via CAT5 cable to an external-grade iMesh router installed on a nearby pole.

A 'chocolate-block' type connector on the back of the cabinet-grade meshI/O unit provides quick and easy connections (see figure 2).
