Full Systems
The Full System product is an option available as a retrofit kit or factory installed equipment
on The Advantage Series, Multi Product Dispenser (MPD-3), Encore, and Eclipse lines of fuel
dispensers. The TRIND device is connected to the CRIND through a gateway or serial
interface board. In this application TRIND is a software slave to the CRIND and the associated
POS controller/host. This means that a properly working TRIND system will look for and read
tags, but only when told to by the controller, through the CRIND application.
This system is to be installed in accordance with all Underwriters’ Laboratory (UL), Federal
Communications Commission (FCC), federal, state, and local regulations associated with it.
The following illustrations depict the system component used in the Original, The Advantage
Series, MPD-3, and Encore Full Systems.
