Hand-held Only Tag System Overview
This product is an option available as a retrofit kit or factory installed equipment in The
Advantage Series, MPD-3, and Encore lines of fuel dispensers. The TRIND Enhanced
Gateway Board (T20678) manages RFID processing and provides simple, generic event
messages to the pump electronics via Transistor-Transistor Logic (TTL). In this application,
TRIND is a software slave to the CRIND and the associated POS controller/host. This means
that a properly working LF 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 UL, FCC, federal, state, and local
regulations. The following block diagram depicts the components for the Hand-held Only Tag
System.
