TECHNICAL FEATURES
Appointment
L2D converter converts from IFSF protocol with LON interface to any dispenser, which supports DART
protocol with RS-485 interface and backwards. It allows POS systems and forecourt controllers, which use
only IFSF-LON, to communicate with any dispenser using DART communication protocol. L2D device is
absolutely transparent in communication providing only conversion of the protocol and interface, so the
POS system thinks that it communicates with IFSF-LON dispenser, no changes from POS are needed.
L2D interface converter can be applied with any POS system able to work with IFSF protocol LON interface
for provision of control over dispensers.
L2D converter is an embedded device that successfully transforms IFSF-LON communication from POS into
DART protocol. It is designed to connect any type of IFSF-LON compatible POS to a non-IFSF dispenser.
