Gasboy FuelOmat system 8 Popt Commverter - Manual (Page 15)

1.3. GENERAL DESCRIPTION
The CommVerter is a Communication Converter, interfacing serial Forecourt devices such as
pumps and tank level gauges to the station automation system through a standard TCP/IP Ethernet
port.
Unlike off-the-shelf Ethernet to Serial interfaces, the CommVerter is designed to function in the
harsh environment of the petrol stations; eliminating ground loops, power surges and other
RFI/EMI noise to maximize the performance and reliability of the station automation solution. Each
link is ‘floating’ and is DC isolated from all other links and has surge protection and enhanced
filtering.
There are two CommVerters configurations: one which is supplied as an enclosed unit which
includes an internal power supply (as shown in Figure 1-1) and the other as a PCB, which is
installed in Gilbarco's products (see Figure 1-2).
