Communication Devices

InvisiLink™ Wireless Radio

InvisiLink™ is a wireless radio solution for devices that communicate via RS-485 or RS-422. A radio is connected to both the measuring device, like a Yo-Yo or controller, and the receiving device, like an ORB. Then the InvisiLink radio sends data back and forth between the devices. This system eliminates the need for cables and conduit connecting a measuring device to a device collecting data. It is also possible to have a single device receive multiple data streams from ‘send’ devices.

Wireless Solution for RS-422 and RS-485 Devices

Eliminates the need for cables and conduit connections between sensors and data collection devices. Standard InvisiLink radio communicates via RS-422 or RS-485 protocols. The 4-20mA converter from Bindicator can be used to allow wireless communications with 4-20mA sensors.

Flexbility with Options

Choose from a standard or extended range antenna for optimal strength of the communication signal. Available as a single radio or incorporated into the Bindicator 4-20mA Input Box to expand connectivity options.
