Figure 1-2. CommVerter PCB - General View
The unit supports a combination of up to 8 serial links of various standards as required at the
forecourt, including: RS-232, RS-485 and current loop.
All links are carried to the station automation controller over one Ethernet port.
The specific protocol for each of these forecourt devices is part of the station automation while the
CommVerter unit is the physical serial interface for the specific devices.
One of the prime tasks of the CommVerter at the forecourt is to interface to the dispensers. The
specific protocol for every dispenser type resides in the “pump server” software module of the
station automation and is standard for all Gilbarco’s home base controllers.
The CommVerter unit is part of Gilbarco’s complete station automation solution and is not an
off-the-shelf standard product, but has a modular structure to enable flexibility for various petrol
stations’ configurations and size.
The CommVerter is a platform with plug-in units to address each specific installation.
